[X2Go-User] Matlab graphics performance when running in x2go

[Johannes Töger]

No flicker. It works well but crashes.

Hi Johannes,

I meant to ask whether Matlab flickers for you when you set the newer Mesa libgl-xlib version in the x2go session.

Best regards,

Aki

No, I haven't tried these. Let me know if you learn something interesting.

Hi Johannes,

When I do the LD_LIBRARY_PATH switcheroo for Mesa libgl-xlib, the OpenGL program Kivy and the test program glxgears
start flickering quite much. Kivy doesn't even work with the default x2go OpenGL version.
Do you experience this and would you have advice on how to get rid of it? The programs still work ok and don't crash.

I'm running x2go server in a Docker container on CentOS 7.

Best regards,

Aki
