Comment 1 for bug 562776

I can confirm this. I have two machines, both running a fully current Lucid system as of the time of this comment. One is an Athlon64 3400+ with 1 gb of ram, the other an Asus Eee 1005PE also with 1 gb. This problem happens on both machines, though it seems much more likely to happen on the netbook. Typically I can kill X and log back in to take care of it, but other times I must do this more than once. This did not happen at all in Karmic nor any earlier version of Ubuntu, and is certainly a regression.
If any type of debug output would be useful, I'll be happy to send whatever is needed.
