To clarify Leon's method a little, the terminal with the Xorg.0.log trace needs to be on the *secondary* screen, and your enter key needs to be held down while focused on it. In my case, this will trigger the bug 90% of the time, and I get those "invalid input device" messages in 40-50 line blocks.
However, if I put the terminal on primary screen, the mouse doesn't get stuck. I still get those "invalid input device" messages, but they are far less frequent in this case. -- [multi screen] mouse position sometimes wrong https://bugs.launchpad.net/bugs/363375 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
