Chaining of x2go via 2 sessions, proxy? What is best solution?
by Buddy Butterfly 12 Jan '14

12 Jan '14

Hi, I have a small box with linux on it as VPN box. This box is headless. So it will be accessed from another computer in the lan. But this box will be used to access the company systems. So the question is, what would be the best solution? 1. x2go to the box and x2go from there to the systems? 2. Install a proxy or the like (do not know if this exists) on the box and connect from 1 x2go client routed via the box? Is probably an ssh forward enough? Thanks and cheers, Matt

Automatic scaling of full screen sessions no longer works
by Jean Gottschalk 11 Jan '14

11 Jan '14

Hello, one of the big advantages of x2go over Nomachine's NX was that scaling of full screen sessions between clients with different screen sizes just worked out of the box. I have recently upgraded to 4.0.1.11, and now this doesn't work anymore, so when I create a session on a desktop with a large screen, then resume it from a laptop with a smaller screen, in full screen mode, I only see part of my screen, which is unusable. I found this information: http://bugs.x2go.org/cgi-bin/bugreport.cgi?msg=2;bug=96 Uncommented the line in /etc/x2go/x2goagent.options, reboot the server and clients just to be sure, and there is no difference. Any other suggestions will be appreciated in order to solve this regression. Jean

CTRL+ALT+T not working in MATE
by Jean Gottschalk 11 Jan '14

11 Jan '14

Hello, I have recently upgraded my Ubuntu installation, which is running x2goserver, to 13.10. I used to use GNOME as a window manager, but since 13.10, gnome seems to require 3D acceleration and can no longer be used with x2go, event in fallback mode (anyone, please tell me if you found a way to make gnome work in 13.10). So I installed MATE and upgraded x2goserver to 4.0.1.11 (Unfortunately both at the same time). Since then, the keyboard shortcut CTRL + ALT + T (which is the only shortcut I am using) is not longer working. After x2goserver upgrade, I have files /etc/nxagent/keystrokes.cfg and /etc/x2go/keystrokes.cfg (which were not there before) and they both contain a definition for CTRL + ALT + T to terminate a session. Not sure what to do next. Is it perhaps a known issue that CTRL+ALT+T does not work in MATE, or perhaps a known issue in the current version of x2goserver? Any advice is appreciated! Thank you! Jean

Thin Client Edition and USB/CD-ROM client-side mounts
by Stefan Baur 10 Jan '14

10 Jan '14

Hi, I added "x2gousbmount" and "x2gocdmanager" to my thinclient image, but all that happens is that I can see USB mass storage media being mounted locally on the client when plugged in. CDs don't show up at all, and nothing (neither USB media nor CDs) shows up inside the X2Go session (where should they show up, anyways? Under which path am I supposed to look for them?). I'm not sure if I made a mistake when configuring the session, though. Is there a man page or wiki page explaining what the session config is supposed look like when one wants to automatically share client-side media? -Stefan

Keyboard mapping issues with Windows client
by Roderick Johnstone 09 Jan '14

09 Jan '14

@Mike Gabriel I have broken this out of the thread "[X2Go-User] [newb] display size ignored". I wanted to clarify the keyboard mapping issues that I'm seeing. I need, at least, to connect to a KDE session from a Windows client with a UK keyboard and from a UK model Mac laptop correctly. When connecting a Windows KDE session I invariably get a US keyboard layout. I'm sorry this post is so long, but its all a bit complicated... My early tests were a bit confusing, I think because the system I'm connecting to has a system-wide UK keyboard setting. So, sometimes tests with xterm seem to be working when its just getting a default. In order to resolve this ambiguity, I've been testing from my Windows laptop with the keyboard set to French mapping which is not a default for the system I'm connecting to or for kde. I've been testing from Windows client 4.01.2 and server package x2goserver-4.0.1.9-2.fc20.x86_64 from the Fedora 20 repo. When I start a single application session (/usr/bin/xterm) the only setup that seems to get the correct French keyboard mappings is when I explicitly set the Keyboard layout to fr and the Keyboard model to pc105/fr. Choosing either auto for the layout or ticking the checkbox "Keep current keyboard settings" does not result in a French layout. (In both cases I get a UK keyboard layout which is the system default for the system I'm connecting to). Having established how to get the correct keyboard mapping in a plain xterm I try a kde session with the same client keyboard settings; now I get a US keyboard layout, which I suspect is a kde default. I'm doing a setxkbmap -print >& /tmp/temp.lis very early on in /usr/bin/startkde and I can see that at that point a French keyboard is set. However, by the time the KDE session is running and I can type into a konsole I have a US key layout. (Logging in to a KDE session at the console on this system gets me a UK keyboard as expected). I thought that maybe KDE is setting its own US keyboard map (or just defaulting to US) so I took some advice from the Fedora KDE list on how to stop KDE setting its own keyboard map. However, that had no effect. I still get the US keyboard map. So, I think there are at least two problems: 1) For the simple xterm session setting the layout to "auto" or checking the box "Keep current keyboard settings" is not working. 2) KDE is possibly overriding the already set keyboard map with a US layout. Is it likely that the nightly Windows client builds will address both these issues or perhaps just 1)? Can you confirm that its possible (for you) to get a KDE session with the correct keyboard mapping that is not the default? Thanks Roderick

wrong keyboard layout
by Giuseppe Barichello 09 Jan '14

09 Jan '14

Hi all, after last packages upgrades (debian testing) I began having problems with keyboard layout. The configuration falled back to "us", while my client is configured as "it". Looking into session logs I found a warning about being unable to stat file /usr/local/lib/nx/X11/xbd/rules/xorg. Indeed there is no "nx" directory under /usr/local/lib in my system. I fixed with: mkdir /usr/local/lib/nx ln -s /usr/share/X11 /usr/local/lib/nx/X11 I don't know if this is correct. I suspect a bug in latest packages... Giuseppe

Pulseaudio muffles sounds from other applications in Windows 7
by rené 09 Jan '14

09 Jan '14

Hello all, I just upraded from version 3.99 (I think it was) to the latest - 4.0.1.2. I both the previous version and this one, I found that when pulseaudio.exe runs (starts when x2goclient i started), sound from Youtube and other applications is muffled and turned down slightly (audible). Killing pulseaudio.exe would remedy that. I don't need sound in x2go-client and I would have hoped that having sound disabled in my profile, I wouldn't have to kill pulseaudio.exe every time I run x2goclient.. but no. Anyway.. in 3.99 I would kill pulseaudio.exe and all would be fine, but then I upgraded to 4.0.1.2 .. now I can kill pulseaudio.exe, but it will immediately be restarted.. Urgh.. Now I have to rename the pulseaudio.exe file so x2go can't restart it. My question: Could you please make it possible to either not install pulseaudio at all or at least produce a clever way of not having x2go start it at runtime? Cheers and thanks for an otherwise great application :) /rené

wmctrl problems
by Jean-Francois Dagenais 07 Jan '14

07 Jan '14

Hi all, Running x2go server on ubuntu (12.04), and my terminal is a mac running XQuartz (with quartz-wm) and the Qt x2go client. I used the Published apps rootless and spawn a few windows from the server. Things run pretty smoothly and Im happy with the performance. The thing that hurts is related to window management. Heres a relevant output: $ echo $DISPLAY :50 $ wmctrl -l Cannot get client list properties. (_NET_CLIENT_LIST or _WIN_CLIENT_LIST) $ wmctrl -m Cannot get window manager info properties. (_NET_SUPPORTING_WM_CHECK or _WIN_SUPPORTING_WM_CHECK) Whereas if I run the same commands natively on the mac, XQuartz responds correctly to wmctrl. So the problem affects pretty much all tools related to window management I tried. I am no X11 expert, but I am a developer and very familiar with linux systems. Right now I just need a few pointers, any thoughts? Thanks in advance! /jfd

x2go & firefox, overload + lockups
by Carl 06 Jan '14

06 Jan '14

Hello, I do all my work through x2go (central XFCE desktop server for the company) and I run the nightly Firefox builds. Certain web pages lead to my entire desktop turning extremely slow, sometimes completely unworkable. This is with only a wireless lan between my terminal and the x2go server. I understand there's a problem with Firefox here, probably generating too many x events (guess) or similar. However, it doesn't seem like x2go is working optimally when a single application can spoil the whole desktop like this (even when the windows are on a different workspace or minimized). The solution is simply to close Firefox when the desktop grinds to a halt (a few times per day). As one of the pages it happened on was our own web page, I looked at the web code to try to track down the problem, and it was bizarrely triggered when many objects on the web page had the background-size property set to 100% in CSS, so there's definitely a Firefox issue involved. However, I'd like to work out if I can tune x2go to handle this better. I thought, based on how NX worked, that events were handled locally on the server and only sent across the link when needed. I can't confirm if this is involved, but it certainly seems like something can be improved as windows that are not shown shouldn't, reasonably, be able to interfere. Does anyone have any input on this? Advice? Should I report a bug? Many thanks. Regards, Carl

Raspberry Pi as cheap Thin Client

Hi, I just stumbled over http://rpitc.blogspot.de/ - a project to turn Raspis into cheap thin clients. They're including an X2Go client in their image, too. I'd be curious how these boxes perform under load - did anyone on this list try it out already? If no, who owns a Raspi and is willing to give it a try? -Stefan

Hi all, two customers of mine stumbled over problems with the recent X2Go Server upgrades. Issues occurred for sessions that had dots in the session name (because of user names containing dots or because of command names containing dots). These issues will be fixed tomorrow, I am about to release X2Go Server 4.0.1.11 / 4.0.0.9 (Baikal LTS) tonight.

No sound in X2Go TCE (ATTN: @Mike)
by Stefan Baur 06 Jan '14

06 Jan '14

Hi list, I managed to get X2Go TCE running, by following the instructions on http://wiki.x2go.org/doku.php/wiki:advanced:tce:install Everything works fine, except for the sound. All my thin clients don't emit sound. Browsing through the list archive, I found a post from back in October where Mike said it happens due to a permission problem, and he posted two links to GIT where he had patched this (the first patch introduced a typo, which was fixed in the second patch). So I decided to give it a go and simply copy the x2gothinclient_create script from GIT over the one I already had on disk. Sadly, this just made things worse: after removing the chroot directory and rebuilding it with the new version of x2gothinclient_create, neither keyboard nor mouse work, so I can't even log in. Reverting back to the old script, rm'ing the chroot directory and running x2gothinclient_create again fixed that issue - but I still have no sound. Any hints? Which log or config file(s) should I post? -Stefan

I've experienced this on two laptops now. Is this really a bug or is it just a setting on the clientside? Thank you in advance! Kind regards, Mervin

remotely open an existing software session
by Robert Lefebvre 12 Dec '13

12 Dec '13

We are running a forex trading program inside of wine on an Edubuntu 12.04 LTSP server. We have 5 test users setup on the server each running their own trading session, each with their own install of the program in wine. The trading program is left running for each user. I can login to any user on the server with x2go but the trading program is not available when I do, even though it is running for that same user on the server. If I try to start the software from the x2go session it briefly flickers ;it it tries to open but quickly dies. Is there any way to "tap" into that same session running on the server once I am logged in? I guess what I am really asking is whether X2go can run just to enable "viewing of that software session?

Can't cut/paste from XEmacs to Windows
by Nick Ingegneri 11 Dec '13

11 Dec '13

Hi all, Does anybody have a suggestion for this situation: User reported that he was able to cut/paste from Windows to XEmacs, but unable to cut/paste in the opposite direction from XEmacs to Windows. I verified the problem with the following notes: - The XEmacs copy is a simple X highlight of the text in question. - The copied text from XEmacs is making it to the X clipboard and can be pasted to other X windows - The copied text from XEmacs is not making it to the Windows clipboard. The problem appears specific to copying from XEmacs. Text copied from other X windows behaves as expected. Thanks, Nick

Fullscreen session stops working in unity
by Markus Fritsche 09 Dec '13

09 Dec '13

Hello, I googled it, but didn't came up with a solution (probably due to wrong searchterms). I am connecting to a x2go server just fine in fullscreen mode. When I minimize the session (using the top right hot corner) and go back, I can't open the window after the second time I did that (minimize & reopen the window). The session still seems to be working & valid, just I can't see the window. I am using x2go-stable from ubuntu ppa on Ubuntu-13.10 with standard unity (no tweaks). Did someone have a similar problem and solved it? Best regards, Markus

Session Resume through X2gobroker with SSH Proxy

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I set up x2gobroker with SSH proxy with passwordless authentication (auth on broker and proxy, not auth at x2goserver).

Can't open display remotely or locally when using hostname in $DISPLAY
by Nick Ingegneri 06 Dec '13

06 Dec '13

Can anybody assist me with debugging what I am doing wrong in this case? I am running the X2Go client in Window 7 and the X2Go server on a RedHat 6 machine. I would like to have a remote linux host export the display back to the X2Go server, which would then forward it to the Windows 7 client. Starting a new X2Go session, this works on the local host: [user@localmachine ~]$ echo $DISPLAY :84 [user@localmachine ~]$ xhost + access control disabled, clients can connect from any host [user@localmachine ~]$ xclock # note - the xclock starts without problems But on a remote host, I found I could not connect to that display, even with "xhost +" already set: [user@remotemachine ~]$ setenv DISPLAY localmachine:84 [user@remotemachine ~]$ xclock Error: Can't open display: localmachine:84 [user@remotemachine ~]$ As an experiment, I tried setting the DISPLAY on localmachine to use the hostname, after which it could not connect to the display: user@localmachine ~]$ setenv DISPLAY localmachine:84 [user@localmachine ~]$ xclock Error: Can't open display: localmachine:84 [user@localmachine ~]$ xhost xhost: unable to open display "localmachine:84" I'm probably missing something obvious, but don't have any idea what is misconfigured. Thanks!

Sudden problems with x2gobroker

x2goserver and recent GNOME Desktops
by Nikos Skalkotos 05 Dec '13

05 Dec '13

Hi all, Has anybody succeeded on connecting on a system that has a recent version of gnome (3.8 or 3.10)? I tried it in Ubuntu 13.10 and in Fedora 19 and Fedora 20 prerealese. For Ubuntu 13.10 I've used the x2go* packages found in launchpad and for Fedora 19 and 20 the official packages. In Ubuntu there is a gnome-fallback.session file that is link to gnome-flashback.session and there is a gnome-fallback-compiz.session that is link to gnome-flashback-compiz.session The first one uses metacity and should work with x2go and the latter uses compiz, so it probably needs 3d support. If I try to do: gnome-session --session gnome-fallback or gnome-session --session gnome-flashback I get a black screen and in the ~/.xsession-x2go-errors I see lines like this: Script for cjkv started at run_im. Script for default started at run_im. Script for cjkv started at run_im. Script for default started at run_im. gnome-session-is-accelerated: No composite extension. gnome-session-check-accelerated: Helper exited with code 256 gnome-session-is-accelerated: No composite extension. gnome-session-check-accelerated: Helper exited with code 256 There are complains that the fallback desktop in 13.10 requires 3d acceleration: http://askubuntu.com/questions/361617/does-gnome-fallback-desktop-require-a… The required componets for "GNOME Flashback (No effects)" are these: RequiredComponents=gnome-panel;gnome-settings-daemon;gnome-screensaver;metacity; If I create a script in /usr/local/bin: user@ubuntu-desktop:/usr/local/bin$ cat startmyubuntu #!/bin/bash gnome-panel& gnome-settings-daemon& gnome-screensaver& metacity And try to run it in the x2go command I manage to pop-up a crippled desktop but I don't think this is the way to go. In Fedora things are even worse. The available gnome sessions are gnome and gnome-classic and both seem to depend on mutter. This command ends up in black screen: gnome-session --session gnome-classic The required components for gnome classic are: RequiredComponents=gnome-shell-classic;gnome-settings-daemon;nautilus-classic; I have manually installed metacity and tried to execute a script that loaded the required components [root@localhost bin]# cat startmyubuntu #!/bin/bash /usr/bin/gnome-shell --mode=classic & /usr/libexec/gnome-settings-daemon-localeexec & nautilus --no-default-window --force-desktop & metacity & wait But the desktop is even more crippled. Is GNOME still supported by x2go or should we consider it abandoned like we did with Unity when Unity2d was dropped? Nikos

x2go session is the wrong dimensions
by Roderick Johnstone 02 Dec '13

02 Dec '13

Hi Sometimes when starting an x2go session (KDE as it happens) I find that the session is created with dimensions 1920x1200 whereas my client window is eg 800x600. I therefore only get to interact with a small part of the remote desktop. Come someone say please: 1) Why does this happen? 2) How can I prevent it happening? 2) How can I resize the session to match the client window size. Thanks Roderick Johnstone

distributing user settings
by Carl 02 Dec '13

02 Dec '13

Hello, I have recently setup a multi user x2go server, and I think it works great. I've got one issue though, that I would like to ask for help with or ideas about: When creating a session in the client, there's a lot of settings to fill out, so to tell a user how to set their client up I need to send a fairly long email, and it doesn't seem as easy to the user as it is once they are set up. With NX, I could copy a session settings file onto a CD along with the client software, tell the user to install the software and double click on the session file to login. They were then prompted only for username and password in a simple dialogue, and this was no bother at all to the user. (this was before NX4 was released with a very complicated user interface) I'd like to do something similar - find a way to make sure the user doesn't have to set colours and image format, click fullscreen, click to enable audio, set the link speed etc. And I want it to work both for Windows and Linux users. I've seen there's some other client software for x2go that I haven't tried, and maybe that's the solution - I will try shortly. Any ideas would be much appreciated. Thanks :-) Best Regards, Carl

Setting keyboard mapping in KDE sessions
by Roderick Johnstone 01 Dec '13

01 Dec '13

Hi As far as I can see, the x2go client keyboard settings are not respected when starting a KDE session on the server because KDE overrides these with its own settings. For our NX server server I was able to override the KDE settings by setting UserScriptAfterSessionStart in node.cfg to reference a script that parsed the NX session keyboard file and constructed the appropriate setxkbmap command. Is there an equivalent to the UserScriptAfterSessionStart functionality for the x2go server? Thanks Roderick Johnstone

Preseeding Ubuntu remote-login-service.conf
by Kjetil Fleten 27 Nov '13

27 Nov '13

We are successfully using Mike's excellent guide to Unity Greeter with X2Go Remote Login Support. http://sunweavers.net/blog/unity-greeter-with-x2go-remote-login-support One of the things we want to do next, is to tweak the remote-login-service.conf so that username and password are passed to the UCCS-like WebUI of the X2Go Session Broker automaticly. I have tried add a line to the config file, but the syntax is obviously wrong: [Remote Login Service] Servers=MyUCCSTest [Server MyUCCSTest] Name=Remote Login URI=http://x2gobroker.localdomain:8080/uccs/inifile/ echo <mypassword> | thin-client-config-agent <myuserid> I have also tried a lot of other variations over the above, with no success. This test works: $ SERVER_ROOT=http://x2gobroker.localdomain:8080/uccs/inifile/ $ export SERVER_ROOT $ echo <mypassword> | thin-client-config-agent <myuserid> Can <mypassword> and <myuserid> be implemented in a similar way to the conf file ? Anyone that have a good tip ? -- Med vennlig hilsen / best regards Kjetil Fleten Fleten.net AS, Tyinvegen 5151, 2975 Vang i Valdres, Noreg Tlf +47 95861348, ORG nr. 999 542 018 (NO) Søndergade 27, 8740 Brædstrup, Danmark Tlf. +45 41153148 CVR. nr. 35479228 (DK) thats-IT(a)fleten.net, www.fleten.net <http://www.fleten.net>

Started getting weird error: Connection failed. Cannot open display "default display"
by Nicu Stiurca 26 Nov '13

26 Nov '13

Hi all, I'm not sure if this is the right place to post a problem like this. If it's not, kindly redirect me to the right place. The problem: I was working last night using x2go to remote into a server. I got disconnected, and upon trying to reconnect, I started encountering the following error: *Connection failed* Cannot open display "default display" That shows up in a pop-up window whenever I try to connect to the server. In the console, I see the following text right before the error window pops up: start new ssh connection to server: "<my server>" : "<my port>" krb: false ssh connection ok continue normal x2go session Some additional info: I can still do normal X forwarding on the server with ssh -X. Server is running OpenSUSE 12.3. Clients are running Ubuntu 13.04, 13.0, and OpenSUSE 12.3. I get the exact same error from all 3 client computers I've tried. Any ideas? -- Nicu Știurcă \\//./ Live long and prosper.

Is it possible to run the X2Go PXE Server (for X2Go TCE) in a Linux-VServer environment?
by Stefan Baur 26 Nov '13

26 Nov '13

Hi list, I tried to install the X2Go PXE Server in a VServer environment. This failed for several reasons: 1) Linux-VServer isn't included in Wheezy any more, so I had to try it using Squeeze. 2) The nfs-kernel-server package cannot be installed in a VServer environment - this is a general limitation of Linux-VServer (http://linux-vserver.org/Frequently_Asked_Questions_scratch#NFS-server) Said FAQ and "apt-cache show nfs-kernel-server" point to the packages nfs-user-server and unfs3 as alternatives. However, in Squeeze, only the nfs-kernel-server package is available, but neither nfs-user-server nor unfs3 are available. 3) unfs3 is available in sid, but only for the m68k platform, not for i386 or amd64. 4) I can't find nfs-user-server anywhere on packages.debian.org (for any release), which means either the package name is wrong or the package no longer exists. So it seems I'm stuck. Other PXE boot solutions use http/ftp instead of nfs and pass along the client root file system as squashfs. I'm not sure if switching to that method would help much, though, as it means having to load the entire root file system into the client's RAM. At present, the file system needs almost 850 MB of space, which would not fit into my clients - they have between 256 MB and 512 MB. Any suggestions what I could try next? -Stefan

Multimedia over the WAN
by Steve Bergman 23 Nov '13

23 Nov '13

Hi, First off, thank you, so very much, to the x2go team. I support ~100 Gnome (soon to be MATE) desktop users in 4 offices in 3 States using FreeNX, and will be migrating to x2go over the next few weeks as we move to our new Debian 7.2 x2go server. I couldn't continue to do it without you! I'm quite impressed with the multimedia capabilities out of the box. Over the WANs, I can comfortably watch YouTube videos. The video is choppy, but serviceable. And the sound is flawless. Unfortunately, watching the same quality videos in, say, VLC, results in unusably stuttery sound. And even desktop sounds are choppy. The default alert "choing" plays the first few tenth of a second or so, pauses briefly, and then finishes. I assume Pulse Audio is just streaming the sound uncompressed. Is there any way to improve that situation? Any sort of compression (even ssh -C) might be an improvement. Or perhaps there's something that can be done with the buffering? I have managers in remote offices who would have need light usage of multimedia, for viewing multimedia resumés, etc. -Steve Bergman P.S. I enjoyed watching Mike Gabriel's talk from Debconf 13 on youtube, yesterday. I watched the whole thing a couple of times... over x2go from our new server, across town. :-)

x2go in LXC (linux containers) - how to enable sound
by brian mullan 20 Nov '13

20 Nov '13

I've been doing a lot with LXC containers for the past couple years. One potentially very interesting use of LXC is to implement x2go so each user on a single Host PC can have their own LXC container, their own "desktop" (lxde, xfce, mate etc), install their own applications etc all without any changes to the Host OS or interfering with other user's and their container based Desktop environment. If you are not familiar with LXC ... some of you may have read about Docker lately. Docker is based on LXC. There are many great benefits of LXC virtualization vs the hardware virtualization provided by vmware, kvm, virtualbox. Just a few are: - LXC is an order of magnitude faster from a performance perspective since there is no hardware virtualization involved - LXC containers can be created/cloned in seconds - LXC container's share the HOST OS's kernel so Host PC resource utilization is much less Anyway, LXC containers are extremely easy to create. But a default LXC container is usually used for "server" linux applications. But its simple to add any "desktop" environment you want to that server then also add x2goserver, x2goserver-xsession after which that LXC container becomes a great x2go server environment for a user. It is isolated from the Host OS, you can change whatever you want in it and the Host OS is unaffected. Anyway, the point of this note was to describe one area that took a while to figure out. LXC Containers as mentioned previous were primarily designed for "server" not "desktop" use-cases. As such "sound" was not enabled by default in new LXC containers. note: In LXC any Host OS resource is or is not permitted through use of a CGROUP file for each created Container Even using the Docker "desktop" example: http://blog.docker.io/2013/07/docker-desktop-your-desktop-over-ssh-running-… Sound does not work by default. After 3 weeks of researching, trying various ideas of how to enable sound I finally got it working after some careful reading of the pulseaudio.orgwebsite. I documented how to configure x2go and another post on configuring PulseAudio in the LXC Container to provide Sound on my WordPress blog so to not duplicate things you can find the information here: http://bmullan.wordpress.com/
