What happened to the X2Go Blog?
by Tristan Miller 06 Sep '18

06 Sep '18

Dear all, There used to be an X2Go Blog at <http://blog.x2go.org>, which could be read as an RSS feed at <http://blog.x2go.org/index.php/feed/>. They seem to have disappeared a few months ago. Does anyone know what happened to them? Is there currently any way of getting X2Go-related news (release announcements, etc.) via RSS? Regards, Tristan -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tristan Miller Free Software developer, ferret herder, logologist https://logological.org/ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

tmp files
by richard lucassen 01 Sep '18

01 Sep '18

Hello list, x2go-server writes each 2 seconds AFAICS four tmp files to /tmp/ -rw------- 1 root root 0 Sep 1 09:22 d_If2A_6JI -rw------- 1 root root 0 Sep 1 09:22 b21fnyFKys -rw------- 1 root root 0 Sep 1 09:22 FQVURek_gX -rw------- 1 root root 0 Sep 1 09:22 DMIsk9sy8n Is it possible to move these tmp files to /tmp/whatever/ ? The reason is that I use a tmpfs on /tmp/ but the stats of /tmp directorie are updated on an SSD disk which causes writes to the SSD. R. -- richard lucassen http://contact.xaq.nl/

Heads-Up: X2Go: The Gathering 2018 (2018-11-09 - 2018-11-11) will very likely take place at Stuttgart's hackerspace "shackspace"
by Stefan Baur 30 Aug '18

30 Aug '18

Dear $ALL, since nobody has replied to the call for volunteers for the IT-Kongress event (see <https://www.mail-archive.com/x2go-project@lists.x2go.org/msg00278.html>), and since we've lost a sponsor, compared to the previous years, it is very likely that X2Go: The Gathering 2018 will have to take place at Stuttgart's hackerspace "shackspace" (<https://shackspace.de/>) - "will have to" meaning that we're out of suitable alternatives due to both time/volunteer staff as well as financial constraints. Thus, there will be no voting period regarding the location this year, we'll simply have to pick the only option that seems to be left at the moment. The last-resort fallback option would be Ulm's youth hostel (both as an event location as well as for sleeping arrangements), but this would mean groups of 4 people would have to share one room, as they do not offer smaller rooms - which, judging from previous years' feedback, is not a situation most of our participants would be happy with. This is why we're not offering a poll with Stuttgart and Ulm as options. For Stuttgart, we're looking at a hostel-like place that offers single and double rooms, as well as at a hotel nearby, for people that prefer a higher-quality sleeping arrangement. Details will be published on the Wiki at <https://wiki.x2go.org/doku.php/events:x2go-gathering-2018> as soon as the two sites have confirmed room availability and replied with their booking cancellation terms.

keyboard layout driving me insane
by Neal Becker 27 Aug '18

27 Aug '18

On client side, I have layout set to map caps lock to ctrl. I need this also when using x2go! But it seems hard to achieve. In x2go, I try both 'autodetect keyboard' and 'don't configure keyboard'. I try mate, xfce, lxde. On the server side I would like to try also configure keyboard layout, but I don't find any good way to do it on those window managers. Unfortunately, neither KDE nor GNOME will work (both client and server are fedora 28). Sometimes I seem to hit a combination that works, but then when if the connection is terminated and I try again, it's once again not preserving my key remapping. This is driving me nuts! Any recommendations?

x2go client users don't show up in "users" or "who" (Ubuntu 18.04)
by Alan Broder 26 Aug '18

26 Aug '18

When users connect to our server via ssh or mosh, the "users" or "who" command work properly, and you can see the list of logged-in users. However, when users connect via the x2go client (from Windows or Mac) - they do not appear in either "users" or "who". Has anyone observed this problem and know how to fix it? Alan

Problem installing x2go on RHEL6

I am having problems with x2go so after going through a number of suggestions and running deeper into a hole, I decided to remove and reinstall.

Log-in problem after NVIDIA card update
by Alec Bayo 20 Aug '18

20 Aug '18

Hi all, Asking for help please troubleshooting an issue with x2go. Inbound connections stopped working after I updated the kernel and nvidia drivers on my centos workstation (the x2go server). On the client, the error message says "Connection failed. Failed to start X2Go Agent session with ID account-_____. X2Go Agent terminated unexpectedly. Aborting session startup." [If I attempt a connecion again the client shows a previous apparently pre-existing connection, but I cannot resume it.] On the server, the session log says "Error: Aborting session with 'Unable to open display 'nx/nx,options=...". I have attempted uninstalling and reinstalling x2goserver from epel. This symptoms are similar to an issue Mihai Moldovan resolved for Qianqian Fang in April: https://www.mail-archive.com/x2go-user@lists.x2go.org/msg02809.html However, I do not have the offending line set in LD_LIBRARY_PATH which solved the issue for Qianqian. #Contents of LD_LIBRARY_PATH (this is from env after ssh-in). LD_LIBRARY_PATH=/usr/local/cuda/lib64:/home/[...]/caffe/distribute/lib/::/usr/lib:/usr/lib/python2.7 I also attempted commenting out this setting from .bashrc, and that did not fix it. I've copied below answers to some questions Mihai asked Qianqian. The only strange thing I noticed is that Mihai asked for the contents of /usr/lib64/nx/X11 , and this is empty. The library Qianqian listed in there is located at /usr/lib64 on my server. Some more details below, answering questions that were made on this earlier, similar troubleshooting request. Best regards, thanks for any help, Ale # Please make sure that nx-libs 3.5.99.16 is installed on the server side: Package nx-libs-3.5.99.16-1.el7.x86_64 already installed and latest version # Client up to date: x2goclient is already the newest version (4.1.1.1-2). # Perhaps this is useful, these lines are also from env: QTDIR=/usr/lib64/qt-3.3 QTINC=/usr/lib64/qt-3.3/include SSH_TTY=/dev/pts/1 QT_GRAPHICSSYSTEM_CHECKED=1 QTLIB=/usr/lib64/qt-3.3/lib QT_PLUGIN_PATH=/usr/lib64/kde4/plugins:/usr/lib/kde4/plugins # Contents of /usr/lib64/nx/X11 $ ls /usr/lib64/nx bin X11 $ ls -lah /usr/lib64/nx/X11 total 0 drwxr-xr-x. 2 root root 6 Aug 18 14:28 . drwxr-xr-x. 4 root root 26 Aug 18 14:28 .. $ ls -lah /usr/lib64/nx/bin total 0 drwxr-xr-x. 2 root root 36 Aug 17 21:28 . drwxr-xr-x. 4 root root 26 Aug 18 14:28 .. lrwxrwxrwx. 1 root root 16 Aug 17 16:09 nxagent -> /usr/bin/nxagent lrwxrwxrwx. 1 root root 7 Aug 17 21:28 x2goagent -> nxagent $ ls -lah /usr/bin/nxagent -rwxr-xr-x. 1 root root 4.5M Jul 18 17:47 /usr/bin/nxagent # Where I found the related libraries $ ls -lah /usr/lib64/*NX* lrwxrwxrwx. 1 root root 18 Aug 18 14:15 /usr/lib64/libNX_X11.so.6 -> libNX_X11.so.6.3.0 -rwxr-xr-x. 1 root root 1.3M Jul 18 17:47 /usr/lib64/libNX_X11.so.6.3.0
