First reported 6 months ago. Looks like people have yet to figure out
whether the root cause is in mesa or in VirtualBox.

Title:
  libgl1-mesa-dri in Ubuntu 14.04 causes Cinnamon to launch into
  software render mode

Status in “unity-greeter” package in Ubuntu:
  New

Bug description:
  I tried both release and proposed versions of libgl1-mesa-dri
  (10.1.3-0ubuntu0.1 and 10.1.3-0ubuntu0.2). They both produce the same
  error as shown below:

  $ LIBGL_DEBUG=verbose glxinfo
  name of display: :0
  libGL: screen 0 does not appear to be DRI3 capable
  libGL: screen 0 does not appear to be DRI2 capable
  libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so
  libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so
  libGL: driver does not expose __driDriverGetExtensions_swrast(): /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so: undefined symbol: __driDriverGetExtensions_swrast

  The workaround, as referenced in the following link, is to downgrade libgl1-mesa-dri. I tried downgrading to 10.1.0-4ubuntu5 but it also didn't work.
