check the perms on /dev/dri/card0. make sure your console
user has read/write access to it.
oh indeed, wheel had only "r", I added "w".
Now glxgears starts without complaining that, displays a half-broken
gear and then will crash
i965: Failed to submit batchbuffer: Input/output error
wow! No wonder I cannot use WebGL in browsers, I think this needs to
be solved first.
On my Intel 530:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 530 (Skylake GT2)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 19.1.17
OpenGL core profile shading language version string: 4.50
it works fine - 'vblank_mode=0 glxgears' gives me about 570 fp/s when
ran full screen, on a system from 22/11. Firefox 94.0.1 also works OK
with WebGL - https://cad.onshape.com/check returns some 24 million
