using a xfce compositor with x2go server/client
by Tim Klassen 14 Jul '18

14 Jul '18

I've just installed x2go server on a new desktop running linux mint 19 xfce. (My client is on Ubuntu 14.04.) I was disappointed to find that the xfce doesn't work with this setup. Have I done something wrong? Are there any other ways that I can get a compositor to work with x2go?

Looking for a Swedish Translator for X2Go Components
by Mihai Moldovan 06 Jul '18

06 Jul '18

Hi Our current active Swedish translator stepped down recently. On behalf of the project, I am looking for someone to replace him and continue the well-maintained Swedish translations. If you are interested to help, please subscribe to the i18n mailing list[0]. More information regarding the translation process can be found on the i18n wiki page[1]. Note that most projects also have a README.i18n file in the source code repository, detailing how translations are done. Since we already have Swedish translations, all steps for adding a new translation can be skipped.

Hello all, I am working with a fresh X2Go install based on Debian 9. I recently discovered that the MATE screensaver is not activated when connected through X2Go. When I connect to the server locally, it works fine. Any suggestions? Kind regards, Jens

Keyboard doesn't work from Mac OSX to Scientific Linux 7 x2go server
by James M. Pulver 29 Jun '18

The keyboard is unusable when launching XFCE on SL7.4 via X2Go from OS X. icewm-session works fine on SL7, and XFCE works fine on SL6. We've tried different versions of the Agent with no change... -- James Pulver CLASSE Computer Group Cornell University

login window only
by alaxa＠libero.it 27 Jun '18

27 Jun '18

Hi! I wanted to run the x2go client from the command line to display the "username" and "password" fields only, like it happens when using pyHoca-GUI. The problem is that whenever my users hit the "CANCEL" button they always see the list of available sessions at the right of the window, which I wanted to avoid. I've tried a command line such as: x2goclient.exe --no-session-edit --disable-pulse --session=MYSESSION --close-disconnect --hide-foldersharing --no-autoresume --no-menu I don't want to use the pyHoca-GUI because it's too slow to start (at least in our environment) Thanks, alaxa

Accelerated graphics on headless server
by Arjun Krishnan 15 Jun '18

15 Jun '18

Hi I'm sure this question has been asked many many times before, but I was hoping one of you could quickly point me in the right direction. I have a headless server, and I'm trying to write a file /etc/X11/xorg.conf.d/xxx.conf, but this doesn't seem to be having any effect. Example 20-dummy.conf <https://www.dropbox.com/s/p0jqump05s0s9r6/forx2go-20-dummy.conf?dl=0> or 20-intel.conf <https://www.dropbox.com/s/eqvw4gmtxgn1lh9/forx2go-20-intel.conf?dl=0> I'd like hardware acceleration, the xrandr command, and kodi to work remotely. Currently I get errors that look like this: $ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1916 x 1029, maximum 1920 x 1200 default connected 1916x1029+0+0 0mm x 0mm 1280x800 60.00 320x240 60.00 640x360 60.00 640x480 60.00 800x480 60.00 800x600 60.00 1024x600 60.00 1024x768 60.00 1152x864 60.00 1280x720 60.00 1280x1024 60.00 1360x768 60.00 1440x900 60.00 1600x900 60.00 1600x1200 60.00 1680x1050 60.00 1920x1080 60.00 1920x1200 60.00 1916x1029 60.00* So it seems that x2go does not care about my xorg.conf files at all. Any suggestions? Arjun

stale dated gnupg key
by o1bigtenor 12 Jun '18

12 Jun '18

Greetings I had successfully installed, and have been using x2go for some time (useful software when one has a number of computers to run!). Wanted to install x2goserver on another machine and was running into a number of issues. I believe I have been able to unravel the problem enough to find at least one of the roots of not being able to install even when following the steps published in the wiki. My install was failing when I tried to install the apt-key and by lots of poking and some sideways thinking I have found the issue. Looking in the system where x2go is working happily in /etc/apt/trusted/gpg I find that the key is liked with the following information: pub rsa2048 2011-03-10 [SC] 972F D88F A0BA FB57 8D04 76DF E1F9 5838 5BFE 2B6E uid [ unknown] X2go Debian/Ubuntu Packaging <debian(a)x2go.org> sub rsa2048 2011-03-10 [E] what is interesting is that of the 12 keys listed (likely not that many compared to possibilities) the x2go key is only rsa2048 which might be sufficient but its also listed as 2011-03-10 [E] which I interpret to mean that the key was generated on the date 2011-03-10 but I'm thinking the [E] means that its expired. As renewing the key is not something that I can do as a user I am requesting that someone with the capabilities of modifying the code might please renew and/or refresh the gnupg key and also inform users of the new key (I am assuming that the key would change with renewal/update). Given the rights to do so I would be more than happy to modify the wiki to reflect that new apt-key code. Thanking in advance those doing this - - - (please advise if (including the how) the wiki is to be updated by myself) Dee

installation woes
by o1bigtenor 11 Jun '18

Greetings I was able to setup x2go server on a couple machines about 8 months or so ago and have found the 'system' to be a very valuable tool (it cuts down on the need for more monitors and other peripherals). Just recently I have be working on installing x2go on a different system than previously and I am running into some problems. I have been following : https://wiki.x2go.org/doku.php/doc:installation:x2goserver and https://wiki.x2go.org/doku.php/wiki:repositories:debian The first issue that I am having is that I am unable to add the repository keys. After typing in the command (checked and rechecked a number of times for accuracy) I keep getting the following as a response: $ gpg: keyserver receive failed: No data I have tried using search engines to find some method of resolving this difficulty but I cannot find anything that would fit this circumstance. Please, how do I affect the installation of the site key? Regards Dee

Couple of notes here, I installed x2go server on Zorin. Zorin is yet another Ubuntu derivative with a hopelessly broken Gnome and KDE implementation. I am using Mate or LXDE both of which do work. The Nightly Build connects then immediately disconnects. The Stable works mostly okay. I am having problems with the stable leaving sessions up and not deleting them when I logout. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Forcing connection speed setting based upon IP address
by Steve Bergman 29 May '18

29 May '18

Hi, I have a central LAN, where the X2Go server and many clients live, and several branch offices which connect via the WAN. I used to be able to modify the FreeNX 'nxacl' script to force 'LAN' for local clients, and 'ADSL' for everyone else. Last I looked, there was no such facility in the X2Go server, and the team had posted good reasons (which I can't quite recall) why that file was not coming back. But does X2Go server have a way for me to accomplish what I want? I still find the occasional misconfigured client. Thanks, Steve Bergman

Large latency when opening a new session
by Laurent Pouilloux 29 May '18

29 May '18

Dear X2go-users, for almost 2 years we are using X2GO with VirtualGL to provides visualization tool on our computing facility and it is very efficient tool. However, we are facing a problem with our current setup that seems related to the number of users connected. We have a machine built on a Dell R730 server (40 cores, 512 GB, Quadro P2000) installed on Centos 7. X2go is installed from EPEL repository, in version 4.0.1.22 For about one month, establishing the connection is very slow. As you can see in the log file below, it waits two minutes before to start a first session (lpouillo-1103-1526465870_stDXFCE_dp24) that does not seem to work then create a second one about 10 minutes later(C-lpouillo-1159-1527588238_stDXFCE_dp24) This error seems correlated with the number of active users, including pts (when it is > 80) but I don't see any limits (max pty, max open files, or in x2goserver.conf which is the one by default) that is reached. Do you have any idea on how to diagnose/solve the problem ? Tell me if you need more information. Best regards, Laurent Pouilloux Ex : May 29 11:54:14 visu systemd-logind: New session 17176 of user lpouillo. May 29 11:54:14 visu systemd: Started Session 17176 of user lpouillo.

I am looking for an option to enable/disable or on mouse click have the X2go windows client grab the keyboard so that all further keystrokes including Alt - Tab combinations would be responded by the remote server. Noticed an issue ((Auto) grab keyboard · Issue #384 · ArcticaProject/nx-libs) logged for this issue that seems to have the fixes committed in Aug 2017. Unable to find any configuration to enable this in the latest X2go client (v 4.1.1.1) downloaded from download:start [X2Go - everywhere@home] Any ideas? Any one got this working?

So, it's a known issue, that eventually will be solved. Thank you for the clarification. Worked around it by disabling drkonqi (export KDE_DEBUG=1 within a kde_debu.sh file, whithin /etc/profile.d/) Thank you all.

Trouble terminating a kde session
by Joao Roscoe 17 May '18

17 May '18

I Have a fresh, up-to-date install of debian 9 x86-64, including x2go from the repos (the package version is 4.1.0.0-0x2go1). So far kde5 is working pretty well. Sure, not as fast as XFCE, but quite usable. With kde5, however, I'm running into an issue at logout: right after clicking the logout button, the display into the session window goes black, and a few seconds later, it shows a dialog stating that ksmserver segfaulted. Clicking "Close" results a briefly displayed second, similar dialog stating the same about drkonqi, and then, after closing that, yes, the session terminates. Using the "Shutdown" button results in exactly the same behaviour. The client is running on up-to-date debian 8 x86 (32 bits). The client package version is 4.0.3.1-4. Has anyone noticed this issue before? Any hints? Best regards, Joao

Problems with java GUI application
by Kevin Kremer 17 May '18

17 May '18

Hi all, I set up an X2Go server to connect to a remote machine and most applications run very well. Unfortunately I rely on one java application where some of its GUI components suffers huge latencies. Here, actions like a click on a button take up to 10 seconds to perform while there is no delay when running the application without X2Go. The latencies can be reduced to 4 seconds by reducing the connection speed to "MODEM" and the image quality to 0. However, the latency is still huge compared to running the application locally. Furthermore, the java application does not re-print its window and it stays blank when minimizing the X2Go window. My setup: I use Xfce as a desktop, the connection speed is set to "MODEM", the compression algorithm is set to 16m-jpeg, the image quality is set to 0 and I use Oracle's JRE 1.8.0_152. The problems also occur when I connect to the host within the same LAN. Maybe someone has encountered similar problem and can give me a few hints for solving them. Best regards, Kevin

installing x2go server on a mostly headless RHEL 7, solving black screen on Windows client
by Heinz Wrobel 08 May '18

08 May '18

Hi, I found a few interesting things when trying to install the x2go server on a somewhat customized and mostly headless RHEL 7 VM in the cloud, specifically in this case on a RHEL 7.2. These findings might help others, so I thought I'd post the details with some side notes. Following the instructions on https://wiki.x2go.org/doku.php/doc:installation:x2goserver for RHEL 7 was not quite enough to install a working server on this specific RHEL 7 VM. Due to the various documented issues with Gnome 3, I had switched the VM to "Server with GUI" with Xfce, but it still didn't help. On installing Xfce I even had to skip a broken dependency regarding sound support to make it install, but that is a side note only in case you also see something like that. I don't care about sound, so that single thing was easy to ignore for me. In any case, when trying to connect with a Windows x2go client, not even the X desktop window on the client showed up initially. Some investigation and log searching revealed that /usr/bin/x2goruncommand relies on dbus-run-session. This RHEL 7 machine only had dbus-launch because its dbus libs are older, and therefore it completely failed to even invoke the Xsession properly. So I hacked x2goruncommand to do the following fallback: ---- typeset dbus_wrapper="$(type -P "dbus-run-session")" typeset dbus_wrapper_args="" if [ -z "${dbus_wrapper}" ]; then typeset dbus_wrapper="$(type -P "dbus-launch")" typeset dbus_wrapper_args="--exit-with-session" fi [...] XSESSION_EXEC="$cmd" STARTUP="/usr/bin/env LD_LIBRARY_PATH=${LD_LIBRARY_PATH} ${STARTUP}" ${dbus_wrapper} ${dbus_wrapper_args} /etc/x2go/Xsession >> "$MESSAGE_FILE" 2>&1 ---- This little hack was good enough to make the client show the server window, but I got a black window only. No remote desktop in sight still. Using htop on the server, I saw that while the x2goagent was running, there was no xfce4 session of any kind or anything else that looked like a process related to any desktop session. After a long set of weird and clueless debug steps I found a problem because I manually invoked "dbus-launch --exit-with-session /etc/x2go/Xsession". It complained about elements in bash-completion.d not being valid identifiers, starting with "_itweb-settings()". Anything bad that can be fixed should be fixed while debugging along, so I started fixing those to see what might happen next. Iteratively I went through the following files in /etc/bash_completion.d to remove the "-" from the function name identifiers only(!) that it was complaining about: - rhn-migrate-classic-to-rhsm - rhsm-debug - rhsm-icon After the manual invocation of the Xsession no longer complained about bash-completion, I tried the client and ... Ta Da! ... the session came up and seems to work well now. I am sure there are other things that may need fixing and your mileage may vary, but all that is for another day. The moral of the story: It's not always just older dbus libs or similar things. Even seemingly unrelated bash completion quirks can make the x2go Xsession script fail to start up ... and not show anything in any obvious log file. BR, Heinz
