Reproduced on Precise using Unity with a LVDS and external monitor. Updated description to define test case.
Thanks for reporting this bug, possibly it is something that needs solved in the window manager rather than X, but it does seem to be deadspace-related so will leave it filed against xserver until it's clearer how this should be addressed. Two separate issues were reported, the second being a similar but unrelated problem with compiz hotspots. We request that each issue be filed as a different bug report. I'm narrowing this bug report to focus on the first issue; please file a separate bug report (against compiz) about the second problem (I'm not entirely sure how to reproduce it, so it would help if you also wrote a more detailed description of it.) ** Description changed: - while this long standing problem has been mitigated with some previous - work and patches (eg: #389519) at least keeping the mouse away from the - dead area, the desktop behaviour is far from being precise still. + [Test Case] + 1.
