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.
