The fix for this bug (in gnome-desktop3 3.2.0-0ubuntu2) seems to break my system: after getting the lightdm greeter and entering my user password to log in, I get a black screen, the screen flickers a few times like if X were crashing a few times. A few seconds later I do get the Unity interface but:
1. I see some things gone wrong in dmesg: [ 41.741320] init: plymouth-stop pre-start process (1900) terminated with stat us 1 [ 53.084817] init: lightdm main process (1271) killed by ABRT signal [ 69.681566] show_signal_msg: 12 callbacks suppressed [ 69.681570] check_gl_textur[2259]: segfault at 84 ip 080486bf sp bfa17a00 error 4 in check_gl_texture_size[8048000+1000] 2. Probably because of the message above about lightdm main process dying, I cannot logout (Unity is gone and nautilus stays running and in control of the root window). I rebooted the machine twice to confirm. Downgrading libgnome- desktop-3-2 to 3.2.0-0ubuntu1 fixes the problem (rebooted after downgrading and didn't get the messages above). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/824099 Title: Max GL texture size can break multi-head To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/824099/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
