Bug#1591: wslvar and wslpath do not work in tmux session that is started on x2goserver

Package: x2goserver Version: 4.1.0.3-5 wslvar and wslpath do not work in tmux session that is started on x2goserver Relevant issues: - tmux: https://github.com/tmux/tmux/issues/3295 - WSL: https://github.com/microsoft/WSL/issues/8706 Environment: 1.

Install and setup WSL2 based on https://docs.microsoft.com/en-us/windows/wsl/install (exact component versions can be found at https://github.com/microsoft/WSL/issues/8706) 2. Install x2goserver in WSL2 based on https://wiki.x2go.org/doku.php/doc:installation:x2goserver 3. Install x2goclient on host Windows system based on https://wiki.x2go.org/doku.php/doc:installation:x2goclient 4. Download tarball from https://github.com/tmux/tmux/releases/tag/3.3a (currently latest version, older version i.e. 3.2a installed via `sudo apt install tmux` also encounters same problem) 5. Install tarball in WSL2 based on instructions at https://github.com/tmux/tmux/wiki/Installing#from-source-tarball 6. Start session on x2goclient and run `tmux` 7. Run `wslvar -S` within tmux session 8. Run `wslpath -w "${HOME}"` within tmux session Expected results: 1. output of `wslvar -S` within tmux should be ``` Name Value ---- ----- ALLUSERSPROFILE C:\ProgramData ... windir C:\Windows ZES_ENABLE_SYSMAN 1 ``` 2. output of `wslpath -w "${HOME}"` within tmux should be `\\wsl$\<distro_name>\home\<username>` Actual results: 1. Running `wslvar -S` within tmux running on x2goserver yields no output 2. Running `wslpath -w "${HOME}"` within tmux on x2goserver returns `wslpath: /home/<username>: Invalid argument` Further information: As mentioned at https://github.com/microsoft/WSL/issues/8706#issuecomment-1211326423, running tmux in WSL2 shell first then on x2goserver causes `wslvar -S` and `wslpath -w "${HOME}"` to work properly but they break if tmux is run on x2goserver first

Bug#1590: x2goclient fails to connect after updating qt5 libs to 5.15.x
by Baese Alexander 15 Aug '22

15 Aug '22

Package: x2goclient Version: 4.1.2.2 Hello all, Just finished a update run in our environment. After that the x2go client could not establish a connection via xfce. After a long bug hunt we found out that updating the qt5 libs actually breaks the client and it will no longer build up xfce sessions (RDP worked flawlessly). Working libs: qt5-qtsvg-5.12.5-1.el8.x86_64 qt5-qtx11extras-5.12.5-1.el8.x86_64 updated to (not working): qt5-qtx11extras-5.15.2-2.el8.x86_64 qt5-qtsvg-5.15.2-4.el8.x86_64 Unfortunately I am not able to post logs / more detailed specs due to regulations. But maybe this can be recreated in a test scenario. Greetings

Bug#1541: x2go graphics issue on MacOS Big Sur
by Kailin Zhuang 12 Aug '22

12 Aug '22

Package: x2goclient Version: 4.1.2.1 I'm using X2Go to run scientific software on our campus compute cluster (since 2019). I recently installed X2Go on a new MacBook Pro 2020 with the M1 chip running Big Sur. Immediately after launching X2Go, the following message repeats about 10 times per minute until I close X2Go: com.apple.xpc.launchd[1] (com.apple.mdworker.shared.XXX): Service exited due to SIGKILL | sent by mds[499]\ When I start Matlab (a scientific application I use for research), the x2go window turns black and becomes unusable. I'm enclosing a screenshot. The same Matlab software works as expected (no display problems) when I run it remotely via ssh (with X11 forwarding enabled) instead of X2Go.
