Dual monitor setup stops mouse from switching screens in Ubuntu 12.04

[Gavin Mendel-Gleason]

When using unity in Ubuntu 12.04 the mouse is unable to traverse to my second monitor. This did not occur prior to the upgrade. It may be related to the panel reveal but turning reveal off did not alleviate the problem.

It probably isn't stuck. You just need to "force" it to the other monitor. You can change a setting to make it like you expect.

Open the CompizConfig Settings Manager (or install it if you don't have it) -> go to Ubuntu Unity Plugin (again, you may need to install this if you don't have it) -> Experimental Tab. At the bottom uncheck Launcher Capture Mouse.

This default behavior is very annoying(especially when you move things from one screen to the other). Maybe you should think about it to not set this option as a default.

Status changed to 'Confirmed' because the bug affects multiple users.

This is, in fact, really annoying and gives the user the wrong sense of the environment. Please, fix it.
