@Chris, Bryce interestingly, after purging the gnome-screensaver package, and rebooting on linux-image-2.6.34-020634rc5-generic, the problem goes away entirely.
However, when using the lucid stock kernel with gnome-screensaver removed, I get a garbled/corrupted screen after the first attempt to switch user. And this time it is fixed by a switch to/from a VT. Summary: this issue is just getting murkier. But Chris might be on to something with the gnome-screensaver/ bug #555870 linkage. -- [RS480] black screen after a few user switches https://bugs.launchpad.net/bugs/546578 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
