Maybe some of these mesa xlib vars might help, too: https://docs.mesa3d.org/envvars.html#mesa-xlib-driver-environment-variables

Then please try to run glxinfo -i (forcing indirect rendering).

Yes,
Thank you for your response.
I tried the following:
export LIBGL_ALWAYS_SOFTWARE=1 export LIBGL_ALWAYS_INDIRECT=1
However, still no success.
glxgears Error: couldn't get an RGB, Double-buffered visual
glxinfo name of display: :50 Error: couldn't find RGB GLX visual or fbconfig

Have you tried settting mesa environment variables like LIBGL_ALWAYS_SOFTWARE and LIBGL_ALWAYS_INDIRECT? (Please google the exact names, cannot check myself right now.)

Hello,
Worked with x2go and Ubuntu 20.04 with no issues with glx. Commands such as glxinfo glxgears worked.
Using a Dell Poweredege Server, we have installed 22.04 and now commans like glxinfo, glxgears do not work connecting remotely to the server using x2goclient
glxinfo name of display: :50 Error: couldn't find RGB GLX visual or fbconfig
glxgears Error: couldn't get an RGB, Double-buffered visual
Mesa 22.0 and higher seems to be the issue.
Reading online, Ubuntu 22.04 no longer supports 'classic drivers' any longer. However, there is a 'mesa-amber' that could potentially resolve this?
Has anyone had any success using mesa-amber and getting commands like glxinfo, glxgears to work in Ubuntu 22.04? I tried the suggested downgrading to Mesa 21 and that just opened up another can worms with dependency issues.
Any help would greatly be appreciated.
Thanks, h.
