There's a patch by Adam Jackson on xorg-devel to constrain the cursor when all CRTCs are reachable which would resolve this bug. I've given it a review, but it was before the holidays and so may have been missed in all the absences.
I'll push this along. ** Changed in: xorg-server (Ubuntu) Assignee: (unassigned) => Chris Halse Rogers (raof) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/389519 Title: Cursor can move off-screen when dual-monitors do not form rectangular area -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
