You have been subscribed to a public bug: Binary package hint: ubuntu-desktop
I just connected a new monitor to my laptop as a secondary screen to check if it has no dead pixels. I then used gnome-display-properties to configure a multi-monitor setup where the external monitor is a bigger (higher resolution) extension of my notebook screen. gnome-display- properties said that it has to create a xorg.conf when I press apply and that i need to logoff and login again. After that it works as expected. The problem is that from then on compiz is deactivated (I suppose this because my GPU isn't powerful enough to drive the virtual screen that gnome-display-properties configures in my xorg.conf) and stays deactivated, even if I disconnect the other screen and remove it's configuration in gnome-display-properties. The actual bug is that when I now try to reactivate compiz in gnome- appearance-properties it just tells me that it can't initialize the driver. There is absolutely no hint as how this problem can be solved or even what the problem is. I could solve this problem by deleting my xorg.conf but most users would get stuck here and there should be a way to solve this problem with the GUI. I think this is a major usability bug. ** Affects: gnome-control-center (Ubuntu) Importance: Undecided Status: New -- gnome-appearance-properties can't load 3D driver after external monitor was attached to laptop https://bugs.edge.launchpad.net/bugs/384308 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
