Well from the glxinfo output you can see the following,
OpenGL renderer string: Software Rasterizer
You can also see that Xorg fails to open the DRM interface:
Code:
drmOpenDevice: node name is /dev/drm0
drmOpenDevice: open result is -1, (Operation not permitted)
drmOpenDevice: Open failed
drmOpenDevice: node name is /dev/drm0
drmOpenDevice: open result is -1, (Operation not permitted)
drmOpenDevice: Open failed
[drm] failed to load kernel module "i915"
(EE) [drm] drmOpen failed.
(EE) intel(0): [dri] DRIScreenInit failed. Disabling DRI.
As you can see, you're not using hardware acceleration.
You must make sure your user is in the wheel group,
/dev/drm0 has no world read/write permissions.
