This affects me on an HP Envy 14 (intel + AMD 5650). After installing fglrx I wasn't able to access my desktop. I purged fglrx and tried Andrikos' PPA, which didn't help. After purging everything, I was able to get LightDM up only after switching to the AMD card via vgaswitcheroo. But then logging into my account dumped me back to lightdm again. The only thing that worked was launching a Guest desktop instance.
No amount of purging and downgrading could salvage my system, I had to re-install 12.10. I never installed fglrx on 12.04 so I can't say whether this is a downgrade. But the opensource radeon drivers on 12.10 seems like a downgrade because HDMI switching doesn't work for me. I'll make another partition to do more testing, so if anyone wants to see any console output/logs, let me know. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1068404 Title: Low graphics mode in Hybrid ATI/Intel GPU systems after fglrx upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1068404/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
