[Bug 1309484] Re: upgrade to ubuntu 14.04 fails

Tue Apr 22 08:29:39 UTC 2014

It's not just enough to disable the PPA, you must revert to the official
xorg packages using ppa-purge. From your latest apt.log you still have
the following packages installed:

xserver-xorg-video-intel [ i386 ] 2:2.99.911+git20140331.5c0623b5-0ubuntu0ricotz~saucy
xserver-xorg-video-nouveau [ i386 ] 1:1.0.10+git20140220.480f0998-0ubuntu0sarvatt~saucy
xserver-xorg-video-radeon [ i386 ] 1:7.3.99+git20140317.bdc41204-0ubuntu0sarvatt~saucy
on libglapi-mesa [ i386 ] 10.2.0~git20140331.ec4b8d16-0ubuntu0ricotz~saucy
