Public bug reported: I already filed this bug when I used the xorg-edgers ppa. Now I purged it but that doesn't help. So here is the description again, updated with the new lightdm version and a detailed description on what happens.
On my system, lightdm fails to start whenever I try to start it with enabled "type=weston" under "[SeatDefaults]" in my lightdm.conf. The logs are from my current system start, where the weston-option was enabled at startup. I got the error "Your system is running in low- graphics mode" but if I went through the menu, and chose to run with low graphics, I didn't get the login screen - I saw the startup output and got to the console with Ctrl+Alt+F1, from where I disabled the weston- option and rebooted. lightdm version: 1.3.2-0ubuntu1+compositor1 ** Affects: lightdm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1032806 Title: lightdm doesn't start if weston is activated (12.10 with system compositor ppa, nouveau) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1032806/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
