I would like to run some headless unit tests, my problem can be recreated with just glxinfo. I try to run:
xvfb-run glxinfo
It prints multiple lines about GLX:
Xlib: extension "GLX" missing on display ":99".
If I try to run Xvfb on background:
Xvfb :99 &
It prints list of extensions, GLX is also there:
Initializing built-in extension GLX
But still, running:
DISPLAY=:99 glxinfo
Gives same GLX error.
It happens only when I use nvidia driver (tested on 352 and 340 proprietary from repository). Same command works fine after switch to Nouveau. Is this a nvidia package problem? Is there a better way to run xvfb in this case?
