Sigh. OK, I'll put this in the "nvidia, why u no ..." bucket. Go ahead and close the bug, though seems like it would be nice to get a sensible error instead of just a corrupt screen.
(TwinView really only works with two heads. The NVS 450 is basically two video cards on one PCI card with some common support circuitry; TwinView doesn't like crossing from one GPU to the other. Xinerama may be deprecated but it's actually the only option here. If I turn it off and run nvidia-settings, it lets me combine two screens on one card, and helpfully offers to make the third screen a separate X display...) For now I'm happy to run without compositing, I'm just afraid some day I'll fall off the bottom of what you're willing to support. :-) I wonder if nouveau will ever work well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/876193 Title: Unity 2D is screwy with my three-head Xinerama To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-2d/+bug/876193/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
