Hi,
it's complicated. I will try to answer this after returning from vacation in a few weeks.

Hello,
Long-time x2go user, just now decided to chase this problem I've been having for a couple years.
Server is x2goserver 4.1.0.6-0x2go1+git20230818.1994+12.main.1 on Debian 12.8. Client is X2Go Client v. 4.1.2.2 (Qt -4.8.6) on Windows 10.
I am using "single application" mode along with uLauncher to create a mostly-seamless remote X experience.
Unfortunately, if I launch any application that attempts to create an OpenGL context, x2goserver crashes instantly. I cannot even run "glxinfo" within the x2go session, although I can use a direct SSH terminal to run it in indirect render mode against the x2go display. Doing so gives the output in the included text file.
This stops me from doing anything with any applications that require accelerated 3D graphics, such as FreeCAD, KiCAD, and a variety of games.
It's not so bad that I can't run a game; that would be a terrible experience. But it is bad that x2goserver completely crashes.
Should this work at all? I guess x2goserver shouldn't crash, in any case.
I see what look like relevant core dumps in journalctl, but I don't know how to gather that up to provide here.
What debugging information do I need to provide?
Thanks, -Brian
