I get the same problem with the same description except that it only takes a few minutes.
My Hardware is HP Mini 110. It appears that it only works properly using 800x600 for the external monitor, but I can use native 1024x600 for the internal screen. After a few minutes it freezes up in such a way that mouse movement can be seen but nothing can be clicked or typed. Forced rebooting with the power switch is the only option. -- 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/1079440 Title: Random complete freeze using dual monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1079440/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
