Problems with x2go
by Chris 13 Sep '15

13 Sep '15

Hi, I'm a long-time VNC user trying out x2go after many people have recommended it, but I can't get it to work well when trying to set up x2go-sessions from Windows, so if anyone can help me out, I'd be grateful. Issue 1: First I tried "X2Go Client" and that one just keeps crashing on me. I only need to enter the "session preferences" dialog and as soon as I press ok (independent if I change anything or not), the program crashes and Windows tells me "x2goclient.exe has stopped working". Similar crash if I try to start a session. This with X2Go Client v. 4.0.5.0 (Qt - 4.8.6) on Windows 7. I tried an older version 4.0.2.x which did not crash so there seems to be something off with the most recent version. Known issue? Issue 2: So I installed PyHoCa-GUI instead. That one is stable and mostly works. But when I choose "custom command" as the session, it refuses to run any command with an absolute path and only accepts things in places like /usr/bin/. Perhaps it is some path-issue, but it also does not accept things in /home/myname/bin/, which is in my $PATH from the shell. Note: I'm using zsh as my login shell. Is this a bug or am I not supposed to be able to run things with absolute paths? (note: I have double-checked file permissions and the things I'm pointing to under /home are +rw for everyone). I don't want to have to put my session script in /usr/bin/ Question 1: No matter if I use the "X2Go client" or "PyHoCa-GUI", I don't get the keyboard behavior I would like. Using VNC, it will just map each keypress from Windows and pass those symbols into the server, which is important since I use a custom keyboard definition. That doesn't seem to work with x2go as I get pc104/us both if I tell it to "do not set" or "automatically detect". And if I choose "use custom keyboard", I can only select a "standard" keymap, I have no idea how to tell it to use a custom keymap. Is it so that x2go can't handle user-defined keymaps and only handles standard keymaps? Question 2: Font handling. I don't get the same set of fonts when I run through x2go as I get when using VNC as some directories are missing from the font path. Trying to manually add those from inside the x2go session ("xset +fp /some/path/that/works/in/vnc/") gives an error. Is there something special with the font handling in x2go that is not compatible with all X11 fonts? Running the same xset command from inside VNC succeeds without problem on the same machine. Version info: the server is running on a Ubuntu machine (14.04) with these x2go libs: x2goagent: 3.5.0.32 x2goserver: 4.0.1.19 x2goserver-extensions: 4.0.1.19 x2goserver-xsession: 4.0.1.19 TIA, Chris

Hi dears, I'm new to XGO TCE and following this tutorial http://wiki.x2go.org/doku.php/wiki:advanced:tce:install and everything works fine from the installation of the X2GO server and X2GO PXE server to the boot process of the thine clients BUT after the thine client boots its asks for a username and password. I'm NOT using LDAP for authenticating the thine clients so i tried to create a session for the thine client by editing the file " x2gothinclient_sessions " BUT i do NOT know which parameter i need to change to set the username and password for the thine client authentication and how to associate this configuration with the client MAC address ? so can someone explain that please....Thanks in advance...

x2gobroker suspend mode
by CORDIER Nicolas NEURONES IT 07 Sep '15

07 Sep '15

Hi, Sorry to my English .. I just finish a x2gobroker configuration with 2 x2goserver under RHEL 6_x64 associated with postgres databases. Broker works well to connect on each other but when we use "suspend mode" , x2goclent close windows and we can't access to suspended sessions. If I look in the databases the session status is ok on "s" , and a x2goclient direct access ( without broker) show me suspended session. What wrong , do I need to add options agent on the x2gosbroker-agent configuration ? Thanks Nicolas. Nicolas CORDIER Infogérance CEA CADARACHE Equipe Unix-Linux 0442257952

Running application for multiple users
by Peter Schulz 05 Sep '15

05 Sep '15

I have set up x2go on an Ubuntu 14.04 machine, and it connects and creates a new session fine. However, when I have the first session running an application like Firefox or Thunderbird, then have a 2nd user log in, the 2nd user cannot run Firefox. He gets a message "Firefox is already running". I thought I can connect with multiple users to the same host? It would not be useful if I can only have one connection. Or do I need a session broker for that? Regards Peter

Ctrl+Alt shortcut does not pass into Linux
by Myrice Li 01 Sep '15

01 Sep '15

Hi All, I am using x2go under Windows 7 with the latest VcXsrv. I connect to an Arch server and mainly using Emacs. In Emacs there are shortcut keys like Ctrl+Alt+A and Ctrl+Alt+K. But it seems like Emacs does not aware of these keys. I found I need to change the default shortcut by changing the ~/.x2go/config/keystrokes.cfg So I changed them to the Ctrl+Alt+Fn key like: <!DOCTYPE NXKeystroke> <keystrokes> <keystroke action="close_session" Control="1" AltMeta= "1" Shift="1" key="F4" /> <keystroke action="switch_all_screens" Control="1" AltMeta= "1" key="F11" /> <keystroke action="minimize" Control="1" AltMeta= "1" key="F4" /> <keystroke action="resize" Control="1" AltMeta= "1" key="F10" /> <keystroke action="defer" Control="1" AltMeta= "1" key="F3" /> <keystroke action="ignore" Control="1" AltMeta= "1" key="F12" /> <keystroke action="force_synchronization" Control="1" AltMeta= "1" key="F5" /> <keystroke action="debug_tree" Control="1" AltMeta= "1" key="F6" /> <keystroke action="regions_on_screen" Control="1" AltMeta= "1" key="F9" /> <keystroke action="test_input" Control="1" AltMeta= "1" key="F1" /> <keystroke action="deactivate_input_devices_grab" Control="1" AltMeta= "1" key="F2" /> <keystroke action="fullscreen" Control="1" Shift="1" AltMeta= "1" key="F10" /> <keystroke action="viewport_move_left" Control="1" Shift="1" AltMeta= "1" key="Left" /> <keystroke action="viewport_move_up" Control="1" Shift="1" AltMeta= "1" key="Up" /> <keystroke action="viewport_move_right" Control="1" Shift="1" AltMeta= "1" key="Right" /> <keystroke action="viewport_move_down" Control="1" Shift="1" AltMeta= "1" key="Down" /> </keystrokes> Even after doing this, the Ctrl+Alt+A does not work still. But it seems this file actually take effects. Because the Ctrl+Alt+F does not work like before. Can you give me some hint for this?

Hi, since x2goclient-4.0.3.1-* there is a 'Path' line below the icon at X2Go client -- Session preferences -- Session -- Path What is this line and the corresponding button used for? Neither could I find any documentation about it nor does the source code help me understand its purpose. Thanks a lot for enlightenment. -- Kind regards, René

restricting x2go to published applications
by Andy Balholm 28 Aug '15

28 Aug '15

I would like to set up an x2go server where users can use only one application; they shouldn’t be able to get a full desktop session. I assume I would set up that application as a published application, but how can I disable full-session logins? Andy

by "BOTZ Franck (Administrateur Systèmes et Résea ux) - DDT 67/SIDSIC/Pôle Infra" 25 Aug '15

25 Aug '15

Hi ! I use thinclients (HP T620) with the embedded OS (HP ThinPro) I install the x2goclient (4.0.1.1) on it. My broker (ubuntu server 14.04, x2gobroker : 0.0.3.1) works fine and my server (xubuntu 14.04, x2goserver : 4.1.0.0) too (PPA nightly build). I can open session trough winbind authentification and everything works well. Next step is to allow the possibility of plugging a usb mass storage on the thinclient and connect it on the session wich is open on the x2goserver. It is possible ? If yes, how ? Thanks a lot for your anwer Regards. Franck

X2Go on multiple screen Windows system
by Rob Janssen 21 Aug '15

21 Aug '15

I have used X2Go for some time, server is an openSuse 13.1 system, client is a Windows system. For now it is running Vista, I am trying to replace it with Windows 8 embedded (a HP thin client). The Windows system has two screens. I want to use screen 1 for Windows, screen 2 for a fullscreen Linux desktop. So I configured this in the X2Go client. (use whole display, select display number 2) However, I find that it does not work reliably. This already occurred on Vista, where it initially opens the session in a window and then quickly switches it to fullscreen. Unfortunately the initial small size is sent to the Linux session which adapts by resetting the desktop size, then the full screen size is sent a fractional second later. The result is that my window placement is all messed up. However, after switching to the newer Windows 8 the issue becomes more pronounced, the window now initially appears on screen 1 which is slightly smaller (because of the taskbar) and is then moved to screen 2, at which time the vxcsrv just crashes. I can work around it by starting a new session but it will not be full screen, there is an unused area the size of the taskbar. The server also does not crash when I select Fullscreen as the display mode (without Xinerama), but then I get the fullscreen mode on screen 1 instead of screen 2 as I desire. I see nothing about these problems in the documentation, do other users see those issues and/or is there something I am missing and can use as a workaround? Rob

20 Aug '15

Hello, I'm using PXE thinclient in a gigabit LAN for a GNU/Linux KDE session. I have a two questions/issues: 1) Which is the best compression method? There are a lot of alternatives like "4k-png", which one may I choose? and may I use the "LAN" option? 2) sometimes the "Shutdown system button" in thinclient, doesn't work. I press it but nothing happens. thanks, -- Saludos!! Luciano Andino GNU/Linux user #185103 Santa Fe - Argentina -----------------------------------------------

Hi, I have just succesfully installed x2go 4.0.1.19, both server and client are Debian Linux machines. According to the documentation Mate (which I run on server) is fully supported, however the drop-down field Session Type on client has no Mate entry. How can choose it? Thanks, Tad

Graphical apps stalling in suspended session
by Matthew L. Dailey 17 Aug '15

17 Aug '15

We ran into an odd issue recently that feels like a bug, but I wanted to throw it out to the community to see if anyone else has seen this or has any ideas. When we run a graphical app in xfce via X2Go and then suspend the session, the app continues to run, but significantly slower than if we remain connected. If we resume the session while the app is still running, it resumes its normal speed. This issue seems identical to bug 673 (<http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=673>), but this was closed because it was not reproducible. The simplest way I found to reproduce this is to have gnuplot plot in a loop, so it takes a while. If I use this input file: do for [a=1:200] { plot sin(x+a) } It runs in a reasonable amount of time while logged into an xfce x2go session: $ time gnuplot plot.txt real 0m6.059s user 0m1.348s sys 0m0.124s If I use a sleep first and suspend so gnuplot runs in the suspended session, it takes much longer: $ sleep 5; time gnuplot plot.txt real 2m24.365s user 0m1.516s sys 0m0.176s Another way to reproduce is to run glxgears and then suspend and resume. You’ll see that while suspended, the frame rate is significantly lower, but then resumes normal speed when the session is resumed. Here are the particulars of the server: OS: Xubuntu 14.04.3 (built this to test - we’re primarily seeing this on our Ubuntu 14.04.3 systems with xfce) x2goagent: 2:3.5.0.32-0~668~ubuntu14.04.1 x2goserver: 4.0.1.19-0~1064~ubuntu14.04.1 x2goserver-extensions: 4.0.1.19-0~1064~ubuntu14.04.1 x2goserver-xsession: 4.0.1.19-0~1064~ubuntu14.04.1 Thanks for any help you can provide. Let me know if you have questions or need any other information. -- Matthew L. Dailey Senior Systems Engineer Thayer School of Engineering Dartmouth College

X2Go Centos 6 BROKEN
by Robert Dinse 17 Aug '15

17 Aug '15

I have a number of CentOS 6 boxes still in service. Today one ate a disk so I re-installed it. But the X2Go RPM on ElRepo does not work, it's missing a bunch of things that are neither present in the CentOS repository or the ElRepo repository. Even if I chase them down with rpm.pbone.net and install the missing components it still doesn't work. I don't have time to troubleshoot further, I'm upgrading that machine to CentOS 7, but someone might want to look at this as others may not have that option because it will break something else. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Client folder sharing not working with Windows x2go client
by Peter Schulz 16 Aug '15

16 Aug '15

I have checked the forum for similar threads, and applied the solutions given there, but it does not solve my problem. *The Problem: * I installed x2go server on a Ubuntu 14.04 VM running in XenServer 6.2. Using LXDE desktop, installed LXDE desktop bindings. Using regular Windows x2go client from Windows XP. No problem to create a session and run it. Added a shared folder for c:\Documents and Settings\Admin. The shared folder does not appear in the x2go session. On the server, using "df -h" to display the various disks gives the message: df: '/tmp/.x2go-sysadmin/spool/C-sysadmin-50-1439738979_stDLXDE_dp16': Transport endpoint is not connected sysadmin is the user name on the Linux Ubuntu 14.04 server used to log in to the session. It is the default user of that installation, no other user created. Curiously, when I re-issue the "df" command in the session a few times, the above error does not show again. It only shows the first time, and only if I do not use use sudo to issue the command. On earlier attempts, the path was different and contained "cygwin" somewhere in the middle of the path. But there was also no folder to connect to. *What I Tried: * Client and server can ping each other. I can log in with putty (SSH) to the server. Therefore, basic communications seem to be allright. Tried to disable strict host key checking on the server in the ssh config file. No result. Uninstalled desktop binding package and re-installed it a few times. No difference. I also installed MATE desktop, and installed XFCE. Same result. I understand that XFCE has no desktop binding package (if that package really has anything to do with that). At least, it did get the exact same error. At this point, I would need advice what I can check further, or what logs I can look into, as I do not know what to look for. ML Peter

x2go on RHEL7/CentOS7
by Paul Raines 05 Aug '15

05 Aug '15

We have been using x2go fairly successful on CentOS6 machines now for a while. We are investigating upgrading to CentOS7 and I am now looking at the x2go situation We get our x2go RPMS from EPEL x2goagent-3.5.0.31-1.el7.x86_64 x2goclient-4.0.3.1-1.el7.x86_64 x2goserver-4.0.1.19-3.el7.x86_64 x2godesktopsharing-3.1.1.1-1.el7.x86_64 So far we have not discovered 1) doesn't work at all with GNOME desktop giving the "Oops" screen. Web search seems to imply this is a known issue with GNOME3 with no real solution though I am suprised this is not mentioned in the X2Go wiki FAQ. I hate GNOME3 anyway so can live without it for X2Go 2) works partially with the KDE desktop. There is the kscreen issue that is mentioned in the FAQ. Really unusable unless one does disable kscreen. Need to investigate further what consequences that has on normal logins. 3) installed MATE from EPEL. On first login it looks and works great but when you "Logout ..." to terminate the session it just hangs on a blank background. If you "suspend" the session via force closing the window and then try to reconnect it fails or just takes you right back to the blank background. One can force terminate the session with x2goterminate-session to clear it out and then get a clean login again, but I don't really want my users having to go though this. So my question is really about the MATE issue which I would prefer to use. Anyone have any clues as to what might be going on or a fix? --------------------------------------------------------------- Paul Raines http://help.nmr.mgh.harvard.edu MGH/MIT/HMS Athinoula A.

Hello, I have been using an older version x2go client for a while now and I like it. This morning I tried to install the new version. I uninstalled the old version then tried to install version 4.0.4 (32-bit version) on a 64-bit Windows 7. The install completes however, there are no sign of installed x2go. I tied to install the older version (4.0.3) but the same results. I have turned off the anti virus and run the install as administrator. Any suggestions. Regards, --jh

I will need slotScDaemonError() later and the previous names were a bit of a misnomer. - x2goutils.{cpp,h}: add new show_RichText_Generic_MsgBox() main function designed to replace the show_RichText_WarningMsgBox() function. - x2goutils.{cpp,h}: make show_RichText_WarningMsgBox() use show_RichText_Generic_MsgBox (). - x2goutils.{cpp,h}: new show_RichText_ErrorMsgBox() function as a wrapper for show_RichText_Generic_MsgBox() with a critical icon. - onmainwindow.{cpp,h}: properly handle scdaemon errors with a message box and close the client. - onmainwindow.cpp: manipulate PATH and append /usr/lib/gnupg2/ to it when starting scdaemon. Fixes: #882. - x2goutils.h: add QMessageBox include, fixed compile error. - onmainwindow.cpp: fix typos leading to compile errors. - onmainwindow.cpp: add blocks to switch cases to fix a compile error. Also correctly append to informative_text on one occasion, instead of overwriting it. - x2goutils.cpp: correct typo to fix compile errors. - onmainwindow.cpp: drop a redundant variable and fix empty env check. - onmainwindow.cpp: add more newlines to scdaemon error output. Use trayQuit() method to really quit the client. - onmainwindow.cpp: add debugging output for new scdaemon PATH value. - onmainwindow.cpp: split up PATH value as printed in the error message box by a newline every 100 characters. Makes it look less ugly and fixes truncation issues. - sshprocess.cpp: export PATH variable when running commands. Otherwise, only the first one will respect the new PATH value. - sshprocess.cpp: wrap SSH command prelude and conclusion in double quotes. - sshprocess.cpp: wrap all remote commands with "bash" instead of the unspecific "sh". - onmainwindow.cpp: try to escape shell quotes correctly when using Kerberos/GSSApi when running the xmodmap keyboard sync command on OS X. - onmainwindow.cpp: also escape other shell quotes when using Kerberos/GSSApi. - onmainwindow.cpp: silence compiler warning by casting an int value to std::size_t. - onmainwindow.cpp: silence another compiler warning by not converting from string to int and back to string needlessly. Just use the string. No need for an OS X-specific variable anymore. - onmainwindow.cpp: fix compile error - use QString.toAscii () to get a valid C string representation for tr (). - onmainwindow.cpp: don't terminate if scdaemon exited with non-zero exit code. - sshprocess.cpp: don't use QProcess::start (QString). Qt is trying to be too smart and causes big trouble. Instead, use QProcess::start (QString, QStringList) and pass the arguments as a list. On Windows, Qt will automatically double quote the arguments and duplicate escaped double quotes or escape non-escaped double quotes. On UNIX-like platforms, each element of the list is passed as a unique argv element, so there's no need for quoting them (that's only a shell-internal thing to group arguments.) - sshprocess.cpp: add a bit more debugging - also print out the unmodified raw output of SSH commands. - onmainwindow.cpp: remove now-bogus double quote escaping. - sshmasterconnection.cpp: port QProcess::start () change. - sshprocess.cpp: whitespace/prettify only and a compile fix. - x2goclient.pro: reinstate old lrelease "search" behavior if qtPrepareTool() is not available. This should only happen on EPEL 6, which ships a broken Qt4 version... - onmainwindow.cpp: only set multidisplay mode for non-rootless sessions. - {ui/xsettingsui.ui,xsettingswidget.cpp}: add new "whole display" option for external X server configuration. Part of #883. - onmainwindow.cpp: rename "optionsmd" setting to "optionswholedisplay", which is more clear. - xsettingswidget.cpp: fix compile error: settings -> setting. - sessionmanagedialog.cpp: enable some debugging and make selected sessions configureable or deletable. Fixes: #909. . [ Mike Gabriel ] * debian/control: + Add alternative D for nxproxy: qvd-nxproxy. Allows parallel installation of X2Go Client and the TheQVD client (perl-qvd-client). .

Greyed out buttons in Session Management.
by Paul Raines 24 Jul '15

24 Jul '15

Well, I just realized I have the same greyed out button issue on my X2GO client on my Windows box at home. So this has nothing to do with domains or profile migration. Basically in Session Management all buttons on the right are greyed out except "New Session" no matter what session I select on the left.

Ctrl-S not recognized by x2go OS X client
by Alan J. Broder 23 Jul '15

23 Jul '15

I have a single Linux server that I connect to from x2go clients on both Windows and OSX computers. When I connect to the server from the Windows x2go client, ctrl-s is recognized just fine (for example, within emacs). When I connect to the exact same server, and same application on that server, from an OS X x2go client, the ctrl-s is somehow intercepted and is not received by emacs. Per a suggestion in a previous thread on this topic, running xev shows that the ctrl-s is really being received by X. Interestingly, when running KDE the ctrl-s doesn't work in emacs, however, when using LXDE ctrl-s does work in emacs (same server, same OSX client)! Anyone have ideas about what could be happening?

x2go client windows questions
by CORDIER Nicolas NEURONES IT 22 Jul '15

22 Jul '15

Hi, We want use your product x2goclient windows in a LVS system. We had test the load balancing between two servers from x2goclient , it works fine except for "suspend" task. It seem not abnormal. Could you suggest me better method to configure a LVS access from your client - if you know of course- ? Otherwise there is a method to disable suspend button from windows manager ? A simple solution would be to launch client windows in thinclient mode to hide windows manager and suspend button but it appears ( it works under linux client). Greetings Nicolas Nicolas CORDIER CEA CADARACHE System Admin Unix-Linux France.

where are settings stored on Windows
by Paul Raines 20 Jul '15

20 Jul '15

Where on Windows does x2go client store its settings? I removed the /Users/loginname/.x2go directory but when I start X2Go client I still see the sessions I defined. I also uninstalled X2Go and reinstalled but the old session settings are still there. We did a profile migration between domains on the user's files and after that was done x2go stopped working. we are trying to start with a clean slate on the user. Whe she tries to start a session it just hangs forever on status connecting with no text in the log/debug window. If you go into edit sessions several buttons are grayed out include delete so we cannot delete the old sessions. If I make a new session it still does not work. --------------------------------------------------------------- Paul Raines http://help.nmr.mgh.harvard.edu MGH/MIT/HMS Athinoula A.

Error resuming x2go "published applications" session from a different machine
by Prasad Annadata 18 Jul '15

18 Jul '15

I use two different client machines (both run ubuntu, one is 32 bit and one is 64 bit if that matters). X2goserver is running on a 32 bit ubuntu machine. I am trying to connect from client-1 an x2go published application session, suspend it and resume the same session from a client-2. I keep getting the following error. Failed to restore all the required screen depths. Can't resume the NX session on this display. I looked up the error, but I am not able to find a recent discussion on this error and suggested work-arounds involve giving up on the session and creating a new session, which beats my original purpose. I have verified that both client machines run at 24 bit color depth. Any ideas?

windows keyboard switch problem

17 Jul '15

Hi all! I'm new from x2go, and I install x2go server to the XFCE and client to the windows 7 I use latest package available on the repository for xfce and latest stable for windows. I have some problems: - When I connect with default properties I can't change my keyboard language from us to ru, but num lock panel work fine. - when I manually set language on the client side to ru I can't switch it to us and my nul loc panel dont work. What can I do about it? Maybe someone use another distro without this problem? Thank you for all reply! -- Best regards! Mishin Nickolay

[x2go][pyhoca-cli] - Reparent windows using xembed
by Antenore Gatta 16 Jul '15

16 Jul '15

Hi all, I'm one of the main Remmina contributors, a C/GTK application used to connect to a remote server using different protocols. We have an NX plugin, that I'm even not sure is working, so I decided to write an X2Go plugin. So far so good, I was able to implement a kind of wrapper around pyhoca-cli, but as I'm far to be a good developer, I'm having some hard time to try to embed/reparent, the X2Go windows inside our GTK container. This is usually achieved implementing the Xembed protocol, on both side and for what I can see/understand, X2Go, or at least Pyhoca-cli, doesn't. Am I wrong? In the case would it be possible to implement or are you aware of any other approach of doing it? Some references: https://github.com/FreeRDP/Remmina/tree/x2goplugin https://github.com/FreeRDP/Remmina/tree/x2goplugin/remmina-plugins/x2go The "xterm -into windowID" it's just to showcase the fact that the reparenting works. http://standards.freedesktop.org/xembed-spec/xembed-spec-latest.html https://developer.gnome.org/gtk3/unstable/GtkSocket.html Thanks a lot for your precious work and support!

I know you reported this a long time ago, but I'd actually need some additional information about this now, as the bug is reproducible on any system. The most valuable bit of information would be if resizing and Ctrl-Alt-R ever worked correctly. You say "[since] the latest x2goclient upgrade", which implies the behavior was different before. I don't know which version you were upgrading from/to (both would be interesting.) Also, you probably did upgrade x2goserver/nx-libs server side, too, right? Working vs. non-working versions would really be helpful here, too. Mihai

Re: [X2Go-User] x2goserver on Ubuntu Mate 15.04 with 4k monitor and high font-rendering DPI
by Simon Baev 05 Jul '15

05 Jul '15

I saw this setting but for some reason it didn't affect anything when I changed it to 96. Could it be caused by the fact that ongoing (not logged out) session was active on the server (physical console) while I was trying to remotely connect to it via X2Go? The only way I found to connect to that server with reasonable DPI was to create a separate user that runs default settings, but that doesn't seem to be a good fix. -- Simon Am 21.05.2015 um 20:05 schrieb Simon Baev: > > Hello, > > > > I'm looking for a way to run *x2goserver* on *Ubuntu Mate 15.04* > > which is living on computer with *4k monitor* attached.

Kerberos and X@Go Mac Client
by David Ritch 29 Jun '15

I’m having trouble with Kerberos authentication with a Mac client. I am using x2goclient-4.0.4.0-preview2 on a Mac running OS X 10.9.5, connecting to Ubuntu 14.0.4 running x2goserver-4.0.1.19. Here are the symptoms: 1) Connecting with kerberos and ssh works fine. I run kinit to get my tgt, and then ssh works without prompting for any sort of authentication. 2) When I tell X2Go to authenticate using kerberos, it connects without apparent error, but my keyboard mapping is bizarre (and pretty much useless). 3) When I tell X2Go to use the default authentication, it waits for some time (maybe 30 sec or 1 min), and pops up a dialog box, asking for a passphrase to decrypt a key. Whether I click OK or cancel, it then pops up a new dialog box, with the following text: "Received SSH_MSG_DISCONNECT: 2:Too many authentication failures for dritch Invalid state in ssh_userauth_kbdint” 4) When I configure an ssh key pair for passwordless login, and configure the X2Go client to use default user authentication, all works fine. 5) Before, when I used the 4.0.3.2 release client, it had very similar behavior. However, in that case, when connecting using kerberos authentication, it also popped up a dialog box with an scp error message. Am I doing something wrong? How can I make this work? Thanks! David

Unity, Alt+Tab and Alt+`
by Alexey Bashtanov 29 Jun '15

Hello, list! I use x2go client 4.0.1.1 (Qt 4.8.6) and x2go server 4.0.1.19 with unity (ubuntu 12.04) on my server machine and twm on client one. Alt+Tab works perfectly except that it shows all windows icons but not one icon of each type. Alt+` (switching between windows of the same kind) allows only switching to next or previous sibling, switching to any another using e.g. Alt+`+`+` simply closes the switching dialog. Is this a bug, and is there a way to fix it by some kind of workaround? Regards, Alexey Bashtanov

debian testing repo throws error
by Sebastian Urchs 25 Jun '15

25 Jun '15

Hi, I just tried to add the debian repo for my testing system as per the instructions <http://wiki.x2go.org/doku.php/wiki:repositories:debian#adding_this_reposito…>. I replace 'jessie' in the template with 'testing' but on apt-get update, I get the following error message: W: Conflicting distribution: http://packages.x2go.org testing InRelease (expected testing but got stretch) Stretch is the current testing name. Testing seems to be available here <http://packages.x2go.org/debian/dists/>, so I don't know what's causing this. Changing the dist name to stretch fixes the issue - however this will require changes to the sources.d file once the dist name changes in the future (not a big deal but still weird). Just wanted to let you know and would be interested in suggestions. Best, Sebastian

Japsand Maintenance Aftermath a.k.a. "Lessons Learned"
by Mihai Moldovan 24 Jun '15

24 Jun '15

Hi Due to a hanging rm process, we had to restart the server today. After rebooting the machine, it was decided to also update the system to the latest packages version, but still staying on Debian Wheezy (for now.) The server is using a custom kernel module provided by Realtek for its RTL8168 ethernet NIC. An in-kernel driver is available, but proved to be too unreliable, leading to frequent network outages and even machine crashes whenever the network IO load was higher than a few hundred KB/s. The hosting provider has a wiki entry for this issue at this location: http://wiki.hetzner.de/index.php/Installation_des_r8168-Treibers/en Unfortunately, the current driver version as provided by Realtek, 8.040, seems to be incompatible with the old 3.2.0-4-amd64 (3.2.68-1+deb7u2) kernel provided by Debian. As of writing this, I do not know what happened exactly, but most likely the module caused a kernel panic during bootup. Reverting to an older version, 8.037, fixed this issue and let the server boot up correctly again. For future maintenance work, please use this older version, at least on Debian Wheezy. I put the module source code into /usr/src and created a symlink from /usr/src/r8168-current to /usr/src/r8168-8.037.00. --- Other updated packages include Java (version 7 co-installed, the "alternatives" symlink now point to version 7 instead of 6) and Jenkins, including its plugins. A test build run suggests the Jenkins update was successful. Mihai

[copy of the eMail that went to X2Go-Project] Hi Japsand, our server also hosting the X2Go Wiki is currently down for unscheduled maintenance. We cannot provide any ETA for when it will be back up. In case you need to access the wiki, please fall back to http://web.archive.org/web/20150624025754/http://wiki.x2go.org/doku.php for now. The mailing lists are still working as expected. Mihai
