This happens consistently for me in 12.10. It started happening immediately after I upgraded to 12.10. After I log in Unity is usable for a minute or so then it permenantly freezes on both screens. I am able to work around the problem by not using my external monitor but that is no practical for me because I have a netbook with a small screen.
To get out of the frozen state I start another virtual terminal, log in and sudo reboot. My system is an ASUS eeepc. My graphics driver is "INTEL IGD X86 MMX SE2" I am running stock Ubuntu 12.10 I have an external samsung monitor, VGA Additionally I noticed that there is another new bug in this version. When a window runs slow, it dims. This has been standard behaviour for several versions. Now when it dims it also has a flashing or pulsing border. I saw this both in the configuration which hangs and in the non- hanging configuration. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1048230 Title: display freezes To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1048230/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
