I agree with the Xinerama link, although I don't know what the underlying mechanism is yet. There is also a strong suggestion of a link with QT.
I switched from the radeon to the fglrx drivers, and get equivalent behaviour when running these apps -- Xorg crashes as soon as they get UI events. Other people are seeing similar issues on non-Radeon cards. Apps that cause the crash :- VirtualBox OSE VirtualBox PUEL (via Kris Wilis) Skype Opera KeePassX VLC qtpfsgui picard -- skype (and others) cause complete crash of xorg on startup/IO activity https://bugs.launchpad.net/bugs/657966 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
