Just in case someone stumbles upon this: I had similar problem (Saucy after upgrade from 13.04) but with Xorg not even trying to load the radeon driver.
Solution was to install xserver-xorg-video-ati (ati driver triggered loading of the radeon driver). It still puzzles me why radeon driver wasn't loaded directly, but could have been something I've done in the past... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1240428 Title: Radeon drivers not loaded properly after upgrading to Saucy Status in “xserver-xorg-video-ati” package in Ubuntu: Invalid Bug description: After upgrading to Ubuntu 13.10 (Saucy), GDM stops to work (strange colors appearing on screen), and lightdm works using llvmpipe instead of radeon drivers. Performance is really bad and dual screen no longer works. It worked perfectly before upgrading. When loging to the session a message box appears saying "System program problem detected". Unfortunately when I click to "Send report..." nothing happens. The display box disappears automatically after some time. Among other things, I tried to purge all radeon-related packages and reinstalling them again, with no success. Any idea?
