Shutting down a remote computer via x2go
by Ski75 14 Jun '21

14 Jun '21

Working at home I want to shutdown my remote computer in the office via x2go on Friday evening and switch it back on by WakeOnLan on Monday morning. But no matter if i try to switch the remote computer off by pressing the 'Shutdown-Button' in the window of the remote desktop or by entering the command "qdbus-qt5 org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.logout 0 2 2" in the command line, the x2go-Server only logs me off instead of shutting down the remote computer. Is there any configuration option I'm missing or is this the intended bahviour or are I'm just misunderstanding the documentation? https://wiki.x2go.org/doku.php/doc:usage:desktop-sharing?s[]=shutdown "...Be aware, that by selecting 'shutdown' within the shared desktop, the remote system will be turned off!..." x2Go-Version: X2GoClient V. 4.1.2.3 Thanks a lot, Tobias

Performance issues + losing mouse click ability & keyboard events
by Jooris Mettler 03 Jun '21

03 Jun '21

Hi everybody, we currently have some serious issues with x2go on our servers, performance issues plus pretty much exactly what was described here: https://www.mail-archive.com/x2go-user@lists.x2go.org/msg04009.html We have two servers running Ubuntu20.04 LTS with xfce4 (lightdm) with barely any issues for almost 6 months. In the past weeks, several users experienced serious performance issues, followed by the issue that mouse and keyboard are unusable. This issue seems to be resolved (until it appears again) by killing all user processes and logging in again. If I simply quit from x2go client side and reconnect, the issue remains. I don´t see anything "obvious" in the logs, but tbh I don´t even know what I´m looking for. I´m currently trying to reproduce these issues on a VM, but no luck (yet). Someone got an Idea? Best, Jooris

No desktop armbian server debian client
by Jeremy Ardley 03 Jun '21

03 Jun '21

My setup is an armbian server and a debian client. Both are up to date with the latest releases of all software. I have just now installed the latest distro versions of x2go I configured my client to use XFCE and ensured xfce was installed on the server The server starts fine and I can connect from the client and get prompted for password. I can see the session on the server using ps ax 4504 ?

username sessions begin even after reboot without login on Ubuntu 20.04
by h i 26 May '21

26 May '21

Hello, Recently working on a new system using x2go on Ubuntu 20.04 linux. Noticed something different that we never experienced previously on 18.04. Reboots usually clear all sessions per user. After reboot on 18.04, you would see the following output from the linux command: %ps -elf | grep username 4 S username xxxx 1 0 80 0 - xxxxx - 15:20 ? 00:00:00 /lib/systemd/systemd --user 5 S username xxxx xxxx 0 80 0 - xxxxx - 15:20 ? 00:00:00 (sd-pam) However, after reboot on the Ubuntu 20.04 system, I see the following output: 4 S username XXXX 1 0 80 0 - XXXX - 20:44 ? 0:00:00 /lib/systemd/systemd --user 5 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 (sd-pam) 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/bin/pulseaudio 0 S username XXXX XXXX 0 99 - - XXXX - 20:44 ? 0:00:00 /usr/libexec/tracker-miner-fs 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/bin/dbus-daemon --session --address=systemd: --nofork --nopidfile --systemd-activation --syslog-only 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfsd 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfsd-fuse /run/user/1020/gvfs -f -o big_writes 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-udisks2-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-gphoto2-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-afc-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-mtp-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-goa-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/goa-daemon 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/goa-identity-service This behavior occurs after login to x2goclient for just one time. The usernames appear in the "top" commmand output with goa-identity-se process despite not logging for a x2goclient session after a reboot. Is there some setting one can change in x2go for Ubuntu 20.04, so these processes aren't running if a person hasn't logged in x2goclient session after reboot? Thanks. h.

Request for assistance - x2go HTML client
by Jan Bergner 22 May '21

22 May '21

Hello all, I am trying to set up the x2go HTML client on a Debian server following this instruction: https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient My setup is done with Ansible, so the setup can be reproduced. The git repo containing the role can be found here: https://gitlab.com/jbergner/ansible-x2go-htmlclient Right now, it should be considered a BETA version (using snakeoil-certificates, etc.), but that is not the point. The x2go HTML client is accessible and it seems to be starting a session. However, this session is closed shortly after the initialization. Unfortunately, I cannot seem to find out, why. May be, someone can help? From start to end of the session, I get the following in the nginx access log: 192.168.122.1 - - [10/May/2021:22:38:57 +0200] "GET /assets/x2go-plugin/IMG/x2gobg.svg HTTP/1.1" 200 10261 "https://192.168.122.126/assets/x2go-plugin/" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:04 +0200] "POST /assets/x2go-plugin/RPC/x2gorpc.cgi HTTP/1.1" 200 2180 "https://192.168.122.126/assets/x2go-plugin/" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:19 +0200] "GET /x2gows/50001 HTTP/1.1" 101 17 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" nginxes error log: 2021/05/10 22:38:58 [error] 1516#1516: *2 FastCGI sent in stderr: "Scalar value @out[2] better written as $out[2] at /var/www/html/assets/x2go-plugin/RPC/x2gorpc.cgi line 79.

Move from freenode?
by Ulrich Sibiller 21 May '21

AFAIKS freenode is not the network of choice anymore: https://mniip.com/freenode.txt So should we move to libera? Or elsewhere? Or drop the chat altogether? Uli

Session terminated instantly, seemingly with no errors
by Matteo Guareschi 19 May '21

19 May '21

Hello, I have been trying to figure this out for a while now. Every time I start a session from my client (arch) to my server (arch xfce), the session seems to start fine, but terminates instantly. The client reads: Info: Proxy running in server mode with pid '11128'. Session: Starting session at 'Sun May 16 15:24:13 2021'. Info: Using errors file '/home/matteo/.x2go/S-matteo-50-1621203851_stDstartxfce4_dp24/sessions'. Info: Using stats file '/home/matteo/.x2go/S-50/stats'. Loop: WARNING! Overriding auxiliary X11 port with new value '1'. Warning: Overriding auxiliary X11 port with new value '1'. Info: Using abstract X11 socket in kernel namespace for accessing DISPLAY=:0. Info: Connecting to remote host 'localhost:40084'. Info: Connected to remote proxy on FD#5. Info: Connection with remote proxy completed. Loop: WARNING! Unrecognized session type 'unix-kde-depth_24'. Assuming agent session. Warning: Unrecognized session type 'unix-kde-depth_24'. Assuming agent session. Info: Using ADSL link parameters 1408/24/1/0. Info: Using cache parameters 4/4096KB/8192KB/8192KB. Info: Using pack method '16m-jpeg-9' with session 'unix-kde-depth_24'. Info: Using ZLIB data compression 1/1/32. Info: Using ZLIB stream compression 4/4. Info: No suitable cache file found.Session: Terminating session at 'Sun May 16 15:24:15 2021'. Session: Session terminated at 'Sun May 16 15:24:15 2021'. And the error files in the S-matteo-50-[...] directory are sessions, options and a spool dir. Sessions only says what versions were found. On the server side in the C-matte-50 directory session.log gives the rather uninteresting errors: Error: keyboard file not created: Is a directory Error: Aborting session with 'Could not open default font 'fixed''. before terminating. The system log itself /var/log/user.log does not report any errors, but only terminates the session. The clients file reports only: error opening security policy file /usr/local/lib/nx/X11/xserver/SecurityPolicy At this point I have exhausted my resources. I have tried the client from a different OS and the result is the same. From what I understand the fixed font error is most likely a red herring, but I have installed xorg-fonts-misc for what it's worth, with no difference. Lastly I should mention that the server runs xfce4 fine on the machine itself (using dbus-launch also makes no difference). I would really appreciate any help. -- Matteo Guareschi
