Hi Ulrich -- Anything I can do to help diagnose this problem?

In the second run xterm -display :5 I ran "konsole -display :5" and konsole opened in the NS Agent window. no, please run xterm -display :5 and run konsole from there. This is to ensure all started program will get the right display. Xterm was not previously installed. Installed xterm. It displays an xterm window on NX Agent window. In the shell, I get qt.qpa.xcb: X server does not support XInput 2 qt.qpa.gl: QXcbConnection: Failed to initialize GLX qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 169, resource id: 225, major code: 130 (Unknown), minor code: 47 I think that these are all informational, not errors. Hmm, not sure. At least the xkb thing looks suspicious. 4. In the xterm run startkde (or however kde is started on fedora) I get a popup (not on the NX Agent window) saying "Plasma seems to already running on this display". That's because you skipped the xterm step. The KDE framework is referring to the local display... (Actually, I previously replaced the xterm step with running konsole with the same command line options. The popup was referring to the target, not the local display. Running konsole probably started KDE. But it did confuse the test.) Ran 'startkde' in the xterm window, I get message about XInput 2 and two messages about skipping syncing environment variable BASH_FUNC_which%%. The NX Agent window is otherwise mostly non-responsive. Right or left click does nothing. The cursor does change from | within the xterm to arrow outside of the xterm. There is no window menu or title bar on the xterm window. None of the KDE/Plasma widgets are displayed. If I run 'konsole' in the xterm window, it displays in the NX Agent window. There is no window title or decorations. When I run VNCserver, the KDE/Plasma widgets are displayed. Running konsole does show a window title bar with decorations. ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
Re: [X2Go-User] x2go error after updating from Ubuntu 16.04 to 20.04
Dear Uli, thank you for your fast reply. Indeed, by using --mesa it works but previously it worked simply without the --mesa attribute. I will check the graphic-card driver as blender etc. does not work either but only using x2go. If I am using the server locally everything works quite fine.

[X2Go-User] x2go error after updating from Ubuntu 16.04 to 20.04
Dear everybody, yesterday I updated a server which is used by my team using x2go. The Linux update (Ubuntu 16.04 to 20.04) went well and everything is up and running. x2go works fine too but opening e.g., graphic user interface programs such as blender, paraview, or salome/freecad. The error for e.g., paraview, is: qt.qpa.xcb: X server does not support XInput 2. And a lot of other error messages.
