This appears to be an issue for many. None of the suggested soloutions have worked for me:
cant-login-to-ubuntu-14-04-after-upgrade
- The permissions and state of .Xauthority & .ICEauthority are fine. Home dir is good, /tmp is as it should be.
unity-doesnt-load-no-launcher-no-dash-appears
- Setting the Ubuntu Unity plugin in ccsm did not have any effect.
I am running a provisioned VM from Oracle VBox.
It appears that the XServer isn't loading opengl:
glxinfo
name of display: :0.0
Segmentation fault (core dumped)
The syslog is throwing errors but, not sure why glx is not found:

All this is telling me is that the whale is dead.
lcpci is finding my graphics card:
00:02.0 VGA compatible controller: InnoTek Systemberatung GmbH VirtualBox Graphics Adapter
Additionally, setting the display manager to gdm bricks it.
I can get in to the machine by logging in to GNOME Classic (MetaCity) but no other desktop will work. Except KDE.
