I installed the packages from the xorg-edgers PPA (<https://launchpad.net/~xorg-edgers/+archive/ppa>) on my Natty system a little over a week ago. I haven't seen the problem since. I believe the version of xorg-server in the PPA is very similar to the version in Oneiric, so it's quite possible the bug is fixed in Oneiric.

Can someone test Oneiric and report back?
