x2goclient not mount the spool directory (Ubuntu 10.10)
by Mario OROZ 29 Aug '11

29 Aug '11

Helo guys. I'm trying x2goclient from Ubuntu (but the version Qt, where is the GTK version?) and I see that the print spool directory of the client is not properly mounted on the server. My server is a Debian 6.0 with x2goserver, from the corresponding repositories. I used the mount command to check the server as root, like said John Sullivan III I'm using the ppa repository (launchpad ppa: x2go/stable) to Ubuntu 10.10 Add the user to group fuse in Ubuntu 10.10. I do not see the fuse module loaded with lsmod but the command "sshfs usr @ server: dir local-dir /" works! Someone could indicate how to get sshfs to mount the client's spool diresctorio? Other questions: How to make the printer driver created with x2go, print raw? Without creating the postscript which then results in pdf, let me understand? Thank you. Mario

x2go sound on debian squeeze / SalineOS?
by Christopher Stark 20 Aug '11

20 Aug '11

Hi, I have a server running saline os (based on debian squeeze with xfce) and a client with kanotix (with kde4 and also based on squeeze). I tried to get audio from the server to the client but didn't succeed. I unlocked the audio ports in my router so it should work. Which Audio server would you suggest in my place and does anyone of you know by any chance how I could get sound? Best regards Christopher PS x2go is a great program. I really like it! -- www.neoliberalyse.de | www.klokunst.org | www.projektidee.org

Instructions for manual install from source tarballs on a less well-known distribution
by Ivan Kabaivanov 17 Aug '11

17 Aug '11

Hi all, I would like to switch from freenx to x2go, but I don't use a well known distribution. I have LFS, Linux From Scratch -- a source based distribution. I'm following the instructions from http://wiki.x2go.org/installing_x2goserver_tarball and INSTALL from the x2goserver tarball. but I fail to get it to work. Firstly, the server dependencies are listed as: perl-suid lsof openssh-client openssh-server libconfig-simple-perl makepasswd libdbd-pg-perl libdbd-sqlite3-perl xauth I've installed everything except for perl-suid as this is no longer part of recent perl versions. Not sure how critical this is. Then, I follow the installation details from x2goserver's INSTALL: ========== BEGIN QUOTE ============ TARBALL INSTALLATION OF x2goserver ================================== 1.) USER + GROUP for X2go ------------------------- Set up x2gouser account and its group if they do not exist already: $ addgroup --system x2gouser $ adduser --system --no-create-home \ --disabled-password --disabled-login \ --shell /bin/false --group --home /var/lib/x2go x2gouser 2.) INSTALL x2goserver FILES ----------------------------- Extract tarball and run $ make install in base folder of the extracted tarball. 3.) SUID GROUP -------------- Configure ownership, permissions and setuid user bit of x2gosqlitewrapper: NOTE: The described action have already been performed by the Makefile run, leaving this here for documentation only. $ chown root:x2gouser /usr/lib/x2go/x2gosqlitewrapper $ chmod 2755 /usr/bin/x2gosqlitewrapper 4.) DATABASE SETUP (SQLite only) -------------------------------- $ x2godbadmin --createdb 5.) INIT SCRIPT --------------- Create a simple init script that starts $PREFIX/sbin/x2gocleansessions on system start (runlevel 2-3-4-5). Alternatively, you can add a single line to /etc/rc.local: /usr/local/sbin/x2gocleansessions & ============= END QUOTE ================ Here, there's some debianism, these two commands, addgroup and adduser, must be some debian specific wrappers for groupadd and useradd. Can you please give me the regular groupadd and useradd command equivalents? Also, in some documentation files, I've see mention of a group x2gousers, while here the group name is x2gouser. Which one is it? Then there's the confusion of which packages I really need. So far I'm compiling the below packages in the following order: nxcomp nxproxy nxcompshad nxcompext x2goserver x2goclient I use git for pulling the source by the way. Then I do $ chown root:x2gouser /usr/lib/x2go/x2gosqlitewrapper $ chmod 2755 /usr/bin/x2gosqlitewrapper Then I run as roon x2godbadmin --createdb (I use sqlite) and finally x2gocleansessions Then from another computer I fire up the x2goclient, create a connection and try to initiate it. This is what I get in the console: $ x2goclient ONMainWindow constructor Can't load translator (:/x2goclient_en_us) ! Can't load translator :/qt_en_US ONMainWindows constructor finished, home Directory is: "/home/ivan" read 2 sessions from config file start new ssh connection setting SSH DIR to "/home/ivan/ssh" ssh connection ok continue normal x2go session "x2gostartagent 1024x768 adsl 16m-jpeg-9 unix-kde-depth_24 us pc105/us 0 D KDE" Agent output: "50 4e95e90f6adaf1f7288f53a489a4e605 2449 ivan-50-1312372325_stDKDE_dp24 30004 30005 30006 " starting nxproxy with: "nxproxy -S nx/nx,options=/home/ivan/.x2go/S- ivan-50-1312372325_stDKDE_dp24/options:50" " NXPROXY - Version 3.4.0 Copyright (C) 2001, 2010 NoMachine.

In the debian installtion, I see you use sudo but in the INSTALL file this step is missing. I've install sshfs anf fuse and I believe all the other dependencies. My questions are: 1) Any way to enable debugging on the server side 2) Any way to enable debugging on the client side 3) Do I need to install and use x2goagent Any help/hints/useful links you offer will be greatly appreciated. When I get everything working, I will contribute a nice write-up for use on the wiki. Modesty aside, I believe I write pretty clear and good documentation. As I'm working on my own LFS-based distribution, I will be following the new releases of x2go and will be updating the instructions too. Thanks, IvanK.

Javascript client?
by Daniel Quiroga 17 Aug '11

17 Aug '11

I´ve been thinking about it a lot and, the best way to port x2go to any plataform will be to build a javascript client. i tried the firefox client but it´s not what i am thinking about, i can put my team to work on it but, ¿how will it work? will i need to make some weird crazy x11-javascript port? if i can get the necesary documentation i will build the javascript client for my project but i can make it available for everyone (why not opensource it).

I will comment your description about setup and installation below, so please read the answers to this question there.

If you refer to x2goprint as separate X2go package then you are definitely using (very) old code. Unfortunately, the www.x2go.org site and our wiki.x2go.org pages to give ambiguous info, this should be fixed and brought in sync ASAP (ping@Heinz!!!). The x2goprint script has become part of the x2goserver package and has undergone some changes since then. Please make sure you use the nightly build packages for testing+debugging for now (this is a recommendation that is valid today, in the future we will bump sub-releases in shorter intervals, the x2goserver esp. is very due for such a nano release... Sorry for delays on this). > Q: In testing (where we simulate what we imagine the printing > process to be by doing each step manually) when we issue the .ready > command, why does that only seems to work sometimes as judged by the > x2go print client popping on the XP side?

Back to the lack of an id_dsa file? Again, we're not sure > that printing is invoking the right scripts to begin with. The print job files are stored on the client via SSHFS. The SSHFS file sharing uses a temporary pub/priv key pair, so for this mechanism it is not relevant if you can SSH to and from the server. The SSHFS mount is issued by the server and connects to the client (via a SSH tunnel). > Q: Assuming we get this working, we also assume that on the > Ghostview/Ghostscript side we shouldn't be having to put the name of > the file in the command line, nor actually having to use the command > line.

Yes, this should be so. Please test this with a Linux x2goclient first. If this works then check with the Windows x2goclient and report experienced differences. > Q: Should we be using Posgress instead of SQLite?

The latest X2go code is only available for Ubuntu >=10.04. For older Ubuntu versions you should be able to either o backport X2go from X2go Git o use the server-side packages for Debian lenny (no nightly builds, though): http://wiki.x2go.org/adding_the_x2go_repository_debian > all in all it works well) over Comcast or Fios connection (DSL too > slow).

Is this needed for x2goclient??? I do not think so... The Ghostscript stuff is needed on the client side... However, a PDF viewer will be helpful on the Windows client.

AFAIK /usr/lib64 is a symlink to /usr/lib. So no worries necessary about this. The only thing you should make sure is to have these permissions set on the cups-x2go backend: -rwx------ root root /usr/lib/cups/backend/cups-x2go This permission setting marks the backend in a way that CUPS knows it has to start it with root privileges. Otherwise it is started with user privileges and that will fail in this context. > 2) If we print from the server, we briefly see a job get created > both on the top (right) panel and if we are watching in the Print > Configuration window.

PyHoca: no x2go session
by Paul van der Vlis 15 Aug '11

Hello, I've installed PyHoca-GUI to test it, installation on Debian Squeeze with Gnome was no problem. After starting it, I found an applet. I've started a connection and I got a form where was asked for the password. After giving the password I saw a message that authentication was successfull. But, that was it. I don't see a remote desktop. When I do a mouse-over on the PyHoca-gui applet, I see (translated in English): "Connecting to remote X2go server". Not sure what's happening here. With X2goclient I can connect. What's different? I am wondering the logfile says "WARNING! Connected to remote version 3.4.0 with local version 3.5.0.". I will attach it the file. I will also add the output of pyhoca-cli -d. With regards, Paul. ---------- NXPROXY - Version 3.5.0 Copyright (C) 2001, 2011 NoMachine. See http://www.nomachine.com/ for more information.

Hello, I have customers with x2go installations in a local network behind NAT (fat clients), and I am looking for a way how to connect easy to them. Of cause I can make a port forwarding, or an SSH tunnel from the fat client to my computer, but maybe you have a better and more flexible idea? In earlyer times I used TightVNC. There was the great "-via" command, something like: vncviewer -via henk(a)server.henk.nl 192.168.0.33 Any ideas how to be flexible behind NAT with X2go?

Okay, I will try to find the latest releases (altough I am pretty sure we have that already installed) and install these. But excuse my doubts, the thing is that this problems happens regardless whether the server is v2 or v3. It appears with x2goclient v3 but not with x2goclient v2 connecting to the same server (the same session even)... Have fun, Arnold

Local share appears as a text file in $HOME/Desktop - cluttering the desktop
by Milan Knížek 14 Aug '11

14 Aug '11

Hello, I was finally able to get x2goserver et al working on Arch linux (thanks to all the devs!) and would like to resolve some other matters (some already existed with stable versions of x2go). When sharing a local directory, x2goserver creates a sshfs mount in /tmp, which is linked by $HOME/media/disk/... So far so good. Additionally, there is a file created in $HOME/Desktop: $ cat _home_mu$sshfs-disk$ /tmp/mu_media/disk/_home_mu mu-52-1313337646_stDmk-remote-session.sh_dp24 Is this file (_home_mu(sshfs-disk)) supposed to be clickable and lead to opening of that mounted directory in a file manager? Which file/desktop manager supports that format? (I use PCmanFM in LXDE on Arch linux for managing the Desktop and that file is just displayed as any other ordinary text file.)

Slow internet connection and background personalization
by Daniel Quiroga 14 Aug '11

14 Aug '11

Hi. i have been playing with x2go and i have to say it, it is an awesome piece of software. I want to use it through really slow connections, wich are the better settings with -q and --pack for it? It is possible to personalize the background of the pyhoca-cli? (when the connection is about to show up it shows a background that says "x2go" and i want to put some another image in there.

x2goclient X-forwarding-problem
by Stefan 10 Aug '11

10 Aug '11

Hi all, I've the following setup: * a remote Xserver-session on a client via xdmcp and gdm3. * In this session I want to use x2goclient to access a remote server Starting a X2go-session with x2goclient I get the following error: ... ... Info: No suitable cache file found. Info: Forwarding X11 connections to display '192.168.0.50:0.0'. Session: Session started at 'Thu Jul 14 12:12:50 2011'. Warning: X connection failed with error 'Invalid MIT-MAGIC-COOKIE-1 key'. Session: Session started at 'Thu Jul 14 12:12:16 2011'. Warning: X connection failed with error 'Invalid MIT-MAGIC-COOKIE-1 key'. Obviously there is a problem with the access to the xserver. Using kdm (kde4) instead of gdm3 it works (partly). Maybe the difference is, that gdm3 doesn't use ~/.Xauthority any more. See here: http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=586685 Maybe the proposed workaround helps here. I'll try. regards stefan

Keyboard and X2Go v3
by Arnold Krille 08 Aug '11

08 Aug '11

Hi all, first time on this list. We are using X2Go in our business and encountered a strange problem: With the new x2goclient of version 3.something the keyboard is acting funny. Sometimes Ctrl or Shift hang, much more often Ctrl+Shift hangs. And AltGr always hangs. (Yes, we are germans with german layout:) That means after entering | all the following keys of 'less' become 'ł€ſſ' for example. Suspending the session and logging in again unsticks the keys but thats not really a solution to tell our users and customers... Needless to say that the old v2 works without problems in this regard. Is this a known problem? Is this perhaps even fixed in the development-version? Or is this better to report on the developers mailinglist? Thanks, Arnold

I created a couple of files in the directory that appears when you run the mount command (mentioned by John in the other thread on the list), a pdf file (/ tmp / [remote user's spool directory] / x.pdf) and another named x.pdf.ready (/ tmp / [remote user's spool directory] / x.pdf.ready). Immediately a window appears asking, in the client PC, howprint the file received! That's all, so no problems with the client side, in x2goclient for windows. I do not think the problem is in mounting the user's spool directory. There may be a permissions issue, related to the user x2goprint, which the documentation is added to the file / etc / sudoers, but in the installation on Debian systems is never created. The questionis; to make a debugging or rewriting the scripts cups-x2go and x2go2print (the latter is called by cups-x2go), Having clear which is the road that runs when selecting a printer in cups, the files involved in a print job, directories involved in tehe print job, and what the directory structure that handles x2goserver when a particular user is connected, you could have more knowledge what does the scripts mentioned. I mean the specification of the operation of printing on x2go instalation. Maybe we can find this information on the development list? And know some Perl! :-) regards Mario.

I've got the same problems with the keyboard mapping (I'm also swiss and I use the french variant) with my Windows and Linux x2go client... When I use the Windows client, forcing the keymap in the X2Go client does not map the keyboard at all. When I let it be the defaut, the keyboard is also not mapped (configured with Gnome keyboard setting as fr_CH). This is under Windows 7 64. When I use the Linux client (qt), the keyboard is not completly mapped. The cursor keys does not work, and the "delete" key starts the gnome screen shooter (but it's not configured in the shortcuts in gnome). The good news is that if a switch to the german version (de_CH) than almost all keys are correclty mapped. This is under debian squeeze. Have you tried to configure the keyboard in your X11 session (gnome settings or kde...), not at the X11 level ? <snip> No, I didn't change the X11 settings on my two linux machines. After reading the mail, I changed it in the x2go session on the linux machine (ubuntu, gnome). First I choosed the swiss german mac layout to no avail. Then I changed the keyboard model to all variants but also to no avail. Bad news... Thanks anyway for the help. Tomorrow, I'll try to change to the french layout. If I'm lucky, this helps as described vice versa (priciple of hope...). I keep you informed. Markus

Hi all, Sorry to bother you with my minor problem... I'm using x2go between my Linux machines without any problems, great piece of software. Thanks for this to the developers! The only problem: when I'm connecting from my Mac to the Linux machines, the keyboard is mapped incorrectly. I also tried changing the keyboard settings in the x2go client and X11 on the Mac, to no avail. The mouse is working correctly. On your mailing-list, I didn't found a similar problem nor a solution for my problem nor on the dev mailing-list. My environment: Mac: OS X 10.6.8 (Snow Leopard) x2go client: 3.01-4 / Qt 4.4.3) X11: XQuartz 2.3.6 (xorg-server 1.4.2-apple56) Linux: Ubuntu 10.04 LTS (Lucid) x2go server and client: 3.0.1 As a swiss guy, I'm using swiss german keyboard layout on all machines Any tips to adjust the keyboard setting on the mac client? Thanks in advance. Markus -- Markus PETER Schönenbachstrasse 37 CH-4153 Reinach powered by linux

x2gousers is missing?

Hi all! :-D <blah> Recently i'm taking my time to get my Personal Computers in a more useable and productive state. A very important part of this process/project is getting X2go to run on my systems. </blah> After installing X2go on my main machine (details: see below) i wanted to use it, of course. But when trying to start a session via x2goclient i get no further than while connecting an error dialog appears with this messeage: "Please install this program as SUID x2gouser!" So i thought: maybe there is an issue with the installation process of the packets, and some rights have to be adjusted manually afterwards. But the problem seems to be that a file called "x2gouser" is missing at all!? $> dpkg -L x2goagent x2goclient x2goserver x2goserver-extension \ | grep x2gouser ...gives nothing. Any help/hints on this is very much appreciated. Best wishes, happy hacking and greetings to Treuchtlingen & Kiel! Patrick ps: I `frankensteined´ the "perl-suid" package from "squeeze" using "Depends: perl (>= 5.10.1), libc6 (>= 2.4), libperl5.10 | libperl5.12 | libperl5.14" and installed this manually to get "x2goserver" installed on wheezy/sid.

x2go Mac OS X Lion 10.7
by Neil Hunt 29 Jul '11

29 Jul '11

Bad news to x2go users who have reliance on a mac client. I upgraded to Lion, which has finally left Rosetta/PowerPC emulation in the dust since Apple has begun moving away from it six years ago, and when I went to connect to my x2go server, I immediately get the error: "You can't open the application nxproxy because PowerPC applications are no longer supported." NoMachine NX 3.5 runs strictly on PowerPC and Rosetta emulation and thus is no longer compatible with Lion. NX4 runs on Intel natively and will run on 10.7 Lion. There is the OpenNX client for Mac which I've tested on Lion and connects to my FreeNX server no problem. So the nxproxy library must somewhere be ported to Intel-based Lion architecture? Please advise, we have quite a few users who use x2go mac client and I need to have a support plan for Lion migrations. Thanks, Neil

Hi devs, today I had a chat with Alex about x2goclient, the versioning, the next major version (Baikal) of x2goclient, etc. o we have bumped the version to 3.99.0.0 in Git o the next major stable release will be 4.0.0.0 (x2goclient/Baikal) o Oleksandr will build a Windows x2goclient with that same version number Packages for Debian are building currently, they will enter the nightly builds repos as well as the ,,main'' repos. Please go ahead and test these new versions, please. Report issues to the x2go-dev mailing list, so that we get as many issues fixed before calling the thing 4.0.0.0.

core dev-team testing x2goclient during next week
by Mike Gabriel 22 Jul '11

22 Jul '11

Hi all, thanks to everyone (esp. to John) for taking such a meticulous look at the latest x2goclient 3.99.0.0 (Win32 version). There obviously seem to be quite some open issues that we have to cross-check on our own development/testing systems. Alex (the core developer of x2goclient) will do that ASAP, we hope to come up with some feedback, patches, comments by the end of next week. If that gets delayed, I will let you know about the delay and come up with another timeline. Unfortunately, as X2go is not a commercial project, this cannot be any quicker. We apologize for this!!! If there are people out there you can read/write C code, please feel free to clone git://code.x2go.org/x2goclient.git and cross-read the code. Some other problems, however, may arise from x2goagent, as well. So you might use git://code.x2go.org/x2goagent.git for lecture as well...

RDP packing
by John A. Sullivan III 21 Jul '11

21 Jul '11

Hello, all. We are still trying to address the very poor performance of rdesktop sessions transmitted over NX - much slower than native RDP although we were expecting it to be much faster. In reading the NX documentation, we saw that they have a packing algorithm especially for RDP. However, whenever we enable this packing algorithm, the session aborts. Has anyone successfully used it? How do we troubleshoot this issue? Thanks - John

Fairly severe problems for our Windows users
by John A. Sullivan III 20 Jul '11

20 Jul '11

Hello, all. Internally, we are almost exclusively a Linux desktop shop and our experiences with X2Go are simply amazing. We architected a very powerful back end and the applications just explode on the screen even though all of them are across WAN connections. The X2Go performance is generally much better than our local systems. However, most of our initial clients are Windows users (for the X2Go client) and they are continually complaining about bad performance to the point we have stopped major new rollouts. We bit the bullet and installed Windows on our local systems and . . . they are right. The Windows client performance is much worse. I'll outline what I have seen but I have seen it consistently in 3.0.1-4, 3.0.1.18 with Xming, and 3.0.1.18 with vcxsrv. I also tried Pyhoca (0.7) but it kept mangling my authentication so I cannot report on it. There are two different types of problems. The first is generally laggard response. Typing, screen refreshes, scrolling - everything is generally slower. I would guess this is simply because we must shim a local X server between NX and GDI and it may simply be the way life is. I was hoping it would not be so noticeable. The second problem is far worse, however. It seems that sometimes screen painting of the active application stalls. Again, we've seen this on all three platforms described above. We most often see this in Iceweasel (we are using Debian X2Go Servers). Users will have multiple tabs open and will switch from one or the other or from one widget in an Ajax application to another and nothing happens for literally a minute or two. They can switch to other applications and work there so this is not simply packet loss on the line. The application itself does not update the screen. After a minute or two, everything they typed or the results or their mouse clicks all appear. This is the killer issue right along with the disappearing mouse. We cannot have our users wait for a minute or two every few minutes while they are working on their applications. Again, they can move to a different application and work but their previously active application, usually Iceweasel, just pauses and then catches all events up a minute or so later. Any suggestions on how to troubleshoot and fix this? Thanks - John

My current test environment is 32 bit Windows XP. We have another user testing 64 bit Windows 7. Most of the complaining users are 32 bit Windows XP. The disappearing mouse pointer is an Xming bug. Moving to vcxsrv will solve that. I think 3.0.1.14 was the first to support that but I'm not sure. We are also using an old X2Go Server - 3.0.1-5 I believe. Thanks - John

DRI role in x2go
by Shanon Loughton 20 Jul '11

20 Jul '11

Hi Im trying to understand how DRI works with a linux server display device and x2go. Id like to get opengl rendering completely in software on an Ubuntu server and so far so good - ive installed libgl1-mesa-swx11 which in Ubuntu auto removes libgl1-mesa-glx, and 'glxgears' and 'glmark' run nicely through x2go, considering the HW limitations. For some more complicated applications inc wine im running into openGL errors and im curious if any part of the server's X is still trying to direct render anything? I read somewhere that in the xorg.conf I can locate the device and set "NoAccel" to true which disables DRI and forces ARB shaders or something. Would this be worthwhile? thanks Shanon

The next release (and also the code in X2go Git) contains a Makefile that you can use with make && make install so that x2goclient gets installed to /usr/local/bin. Two options: (a) wait for Wednesday/Thursday, then I will patch code from Alex into the current Git code and after that x2goclient will be releases as 3.0.99.0 (as tarball). (b) clone the current Git code: $ git clone git://code.x2go.org/x2goclient.git and then do $ cd x2goclient $ make && make install Greets, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

x2go und gpg-agent - no decryption of emails via kmail possible
by Stefan 15 Jul '11

15 Jul '11

Hi all, using x2goclient 3.0.99 on debian squeeze (client and server) together with kmail I run into a problem decrypting emails via gnupg. Unlike as with a Xserver-Session there seems not to be a startscript for gpg- agent in x2goserver. But if I start gpg-agent by hand using command "gpg-agent --daemon" still kmail can't decrypt emails. Starting the gpg-agent with the same command on a xsession initiated with "X -query SERVER" it works. One possible reason I guess in wrong environment variables for $DISPLAY - so the pinentry-qt4 gui (or any other pinentry-gui) could not start. So kmail ends up in "wrong passphrase". This problem allready went up in x2go on debian lenny. But the old kmail on lenny brought it's own frontend for decrypting mails without gpg-agent as a fallback - so it was at least possible to read encrypted emails - even if you had to submit your passphrase on every email again (because it's only remembered through gpg-agent). Any Ideas? Regards Stefan

Building X2GoClient from source
by John A. Sullivan III 12 Jul '11

12 Jul '11

Hello, all. I must be tired, brain-cramping, or clueless. I'm trying to put x2goclient onto a Fedora 15 installation. I compiled nxproxy and nxcomp fine once I figured out the dependencies and symlinked nxcomp-version to nxcomp so nxproxy could fine NX.h. But I then downloaded the x2goclient 3.0.1.18 tarball. I did not see a configure file, a make script, or any templates. I did notice several project files so I downloaded kdevelop to open the project files. I've not used Kdevelop4 before (dinosaur that I am). It only wanted to open the x2goclient-libssh.kdev4 project file. However, it cannot build it and there is nothing to create the configure/make files. How does one build this x2goclient from source? Thanks - John

Keyboardmapping <Alt Gr>-Key
by Stefan LAmbert 11 Jul '11

11 Jul '11

Hallo, leider reichen meine Englischkenntnisse nicht aus um den nachfolgend beschriebenen Fehler in Englisch zu beschreiben. Da jedoch, wie ich weiß, ein Großteil der Entwickler von X2GO aus Deutschland kommt, hoffe ich, dass mir trotzdem geholfen werden kann. Dafür möchte ich mich bereits im Voraus bedanken. Jetzt zum Grund meine Anfrage. Wir nutzen schon seit einiger Zeit X2GO und sind damit sehr zufrieden. Alles hat bisher sehr gut und problemlos funktioniert. Das hat sich jedoch leider geändert. Fehlerbeschreibung: Heute habe ich damit begonnen unsere Testserver von der "alten" x2go-Server Version (3.0.1-5) auf die neue Version (3.0.99.5-0~49~lucid1) umzustellen. Hierzu habe zunächst die alte Version gelöscht (purge) und dann die neue Version, wie im Wiki beschrieben, installiert. Beim Test des Servers habe ich dann folgenden Fehler festgestellt: Wird sich auf dem x2go-Server mittels x2go-Client angemeldet, eine Applikation wie z. B. Libreoffice gestartet und dort dann ein Zeichen unter Verwendung der <Alt Gr>-Taste wie z. b. | oder @ eingegeben, so ist ab diesem Zeitpunkt keine "normale" Texteingabe mehr möglich. Auf dem Bildschirm sind jetzt bei jedem Tastendruck nur noch "Hieroglyphen" zu sehen (Screenshots kann ich bei Bedarf gerne übersenden). Einzige Abhilfe schafft eine Ab-/Neuanmeldung am x2go-Server. Das beschriebene Procedere habe ich an mehreren x2go-Clients (Ubuntu 10.04 und 11.04) und mehreren Servern (Ubuntu 10.04 und 11.04) getestet. Der Fehler ist unabhängig von der x2go-Client Version (getestet mit Vers.3.01-5, 3.0.1.18-0~56~lucid, 3.0.1.18-0~56~natty), tritt aber nur bei der Serverversion 3.0.99.5-0~49 (lucid u. natty) auf. Die Tests habe ich an neu aufgesetzten Maschinen und an "upgedateten" Rechnern durchgeführt. Das Ergebnis ist immer das gleiche. Hier die installierten (x2go)-Pakete eines "Problem"-Servers: (dpkg -l | grep x2go) ii cups-x2go 3.0.0.2-0~33~lucid1 ii x2goagent 3.4.0.5-0~40~lucid1 ii x2gognomebindings 2.0.1.1-0~16~lucid1 ii x2goserver 3.0.99.5-0~49~lucid1 Hier die installierten (x2go)-Pakete eines funktionierenden Servers: (dpkg -l | grep x2go) ii cups-x2go 3.0.0 ii nxcompshad 3.4.0-1 ii pinentry-x2go 0.7.5-2 ii x2goagent 3.4.0-3-1 ii x2goclient 3.01-5 ii x2gognomebindings 2.0.1-1 ii x2goprint 3.0.0-1 ii x2goserver 3.0.1-5 ii x2goserver-home 3.0.1-1 ii x2goserver-one 3.0.1-1 Was mache ich falsch, bzw. was habe ich vergessen? Nochmals vielen Dank für die Unterstützung Viele Grüße Stefan Lambert

Kde4.6 x2goplasmoid
by Mirco Rohloff 06 Jul '11

06 Jul '11

Hello, i want to use the x2goplasmoidbindings on my Kubuntu with KDE4.6. So it is no problem to install the deb pakage. But i can't figure out how this will work. When i put the plasmoid on my Desktop i have a big box with a small toggle switch in. If I press it the session go to sleep. This works good but is not really nice. If I put the X2go Plasmoid in the Kicker-Taskbar i have resice it very high to see it in the bar. That is not usable. Screenshot: http://www.rohloff.de/fileadmin/rohloffde/tmp/kde_plasmoid.png Is there anybody who can give me some tips how this thing can be integrated in the Kde4.6-Desktop. Maybe like the X2go-Gnome Switch near the Logout button! Thanks Mirco

Mac client 'Can't connect to X-Server'
by Paul Northug 06 Jul '11

06 Jul '11

Thank you to the developers for make this excellent software. Many people at my work use x2go's Mac client. We have never been able to figure out how to resolve the 'Can't connect to X-Server' error without random acts (eg. rebooting). We are not sure why it comes up. This is what I do: 1. Start X11.app 2. ssh -X remotehost 3. xterm & So far this works, I get an xterm so there is nothing wrong with X11 4. Start X2Go client 5. Start a session (port 22, dsa authentication, Gnome...) 6. Client gives the error and hangs (Abort and Terminate don't do anything) and I have to close the application. The closest we got to figuring it out is that the X11.app possibly changes it's DISPLAY on restarts and perhaps the x2go client is expecting display 0. Is there any more debugging information that I could get from the client to see what exactly it is doing prior to giving the error message? We have tried some of the suggestions in the forums, such as changing permissions in X11.app (this is necessary), starting it manually before starting the client. We have also done things like messed with firewall settings, made sure hostname doesn't change on our laptops between work and home, deleted preference files, delete XAuthority files, etc. What seems to work is rebooting. Thanks, Pål

X2go backport packages for Debian lenny
by Mike Gabriel 04 Jul '11

04 Jul '11

Hi all, Dick Kniep from the Lindix company in the Netherlands has sponsored the backporting of X2go server-side packages to Debian lenny. As many of you still use lenny on the servers, I persuaded him to make this a contribution to the community. That is: you can use this APT line to install recent X2go packages on Debian lenny: deb http://packages.x2go.org/debian lenny main NOTE: we will not backport the client-side packages. This is only for the X2go servers. Unfortunately there will neither be a backport of x2gokde3bindings, which has not been moved into X2go Git.

Hi list, Unfortunately I can not speak English and have therefore used the Goolgle translator. The message appears, therefore, again in German, in the hope that it may be true but from someone gelsesen. I have a problem with the package x2gognomebindings (from https://launchpad.net/ ~ x2go) It generates on my system, Ubuntu 10.10 a Languagemix e.g. When right-clicking a desktop icon, there are three English entries: - Make Link - Move to Trash - Restore Icons Original Size In addition to trash even the entry - Empty Trash The possible deletion message appears completely in English. Nautilus has the entries Back - Forward - Up - Search in English, the rest is German. X2go I use daily and would be happy if it could be a solution of the problem. Sincerely, Mario Eberlein ###### deutsche Meldung ######## Hallo Liste, ich kann leider kein Englisch und habe daher den Goolge Übersetzer benutzt. Die Meldung erscheint daher auch noch einmal in Deutsch, in der Hoffnung das es so doch von jemanden richtig gelsesen werden kann. Ich habe ein Problem mit dem Paket x2gognomebindings (aus https://launchpad.net/~x2go) Es erzeugt auf meinem System Ubuntu 10.10 einen Sprachmix z.B Bei Rechtsklick auf ein Desktopsymbol finden sich drei englische Einträge: - Make Link - Move to Trash - Restore Icons Orginal Size zudem bei Mülleimer noch der Eintrag - Empty Trash Die eventuelle Löschmeldung erscheint vollständig auf englisch. Nautilus hat die Einträge Back - Forward - Up - Search auf englisch, der Rest ist deutsch. Ich nutze X2go täglich und würde mich freuen wenn es eine Lösung des Problemes geben könnte.

Problems with ssh keys and intermediate ssh hop
by Karsten Heymann 28 Jun '11

28 Jun '11

Hi (especially Mike :) ), we're currently evaluating x2go on debian squeeze (server) / ubuntu natty (client). Basic functionality works, but some of our users will need access via an intermediate ssh hop. Now if the x2go clients (I tested x2goclient and pyhoca-gui) would honour ~/.ssh/config, I could simply roll out a ProxyCommand line, but so I have to resolve to setting up the relevant tunnels manually. pyhoca claims to have some support for intermediate hops, but I was not able to use it in any understandable way. What's the recommended way to achieve this feature? Also, pyhoca-gui was not able to accept my rsa private key and claims it's a invalid dsa key (which is correct but not helpful ;) ). If any of this is wrongly adressed here, please point me to the correct place.

Mac client printing
by John A. Sullivan III 27 Jun '11

27 Jun '11

Hello, all. We suddenly have a number of Mac client users. We do understand that sound will not work because there is no pulseaudio for Mac. However, printing is not working either. We have gotten it to work in the past by enabling remote access (sshd in effect). However, we have done that on the last three Mac clients and it has not worked. We have gotten error messages that sshd is not running and yet we have started the service. As most of us here are Mac ignoramuses, any idea why this is not working and how we fix it? Thanks - John
