Haven't seen this bug for some time.

Although, as implementer of the software fallback feature I did notice
that plenty of users could not detect when or if it was active. That's
great news in theory. But also bad if it was active at the wrong time.
If in doubt, use the steps outlined in the bug description.

  Mesa driver can't load)

Bug description:
  After updating today Unity only starts in software rendering mode. I can tell because:
    1. There's no dash blur.
    2. Graphics performance is slow.
    3. .xsession-errors says:
         libGL error: failed to open drm device: Permission denied
         libGL error: failed to load driver: i965
    4. compiz is linked to the software driver:

  $ pmap `pidof compiz` | grep dri
