Here's the description. Log with user A via gdm. Set the screensaver to 1min (blank screen or whatever). fast-switch to user B. wait more than 1 min. Fast-switch to user A. => the screen is blank, no message from gnome-screensaver to unlock. There's only the mouse pointer. I can still switch to console with ALT-Fx, but the screen is blank (I have to type blinded). If I restart gdm, the screen is back. When this happened, I could see via ssh that the gnome-screensaver process of user A launched gnome-screensaver-dialog process with argument --enable-switch and --status-message= I uninstalled gnome-screensaver, made sure its processes were not running and try this: Log with user A via gdm. Set the power-manager to switch off the screen after 1 min. fast-switch to user B. wait more than 1 min. Fast-switch to user A. And the screen was OK. my video card is ATI Technologies Inc RV710 [Radeon HD 4350] and I'm using KMS (default lucid configuration). I'm not using compiz or anything related to visual effects. package: gnome-screensaver 2.30.0-0ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/578979/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
