Just wanted to mention, that I am experiencing the same problem: Sometimes when moving the mouse while the screensaver is running, the hack just freezes and no login dialog is displayed. I then log in through the network with ssh -Y ... and can then open the gnome-system-monitor remotely which tells me that the status of the screensaver hack is "stopped". I can then click on "continue", the hack resumes, and moving the mouse once more finally gives me the login dialog. (Alternatively I can just kill the frozen screensaver-hack and also get the login dialog.) The graphics driver is "intel", by the way.
Another work-around when no network and/or second computer is present: Press alt-ctrl-F1 to jump to the console and kill the frozen screensaver-hack (not gnome-screensaver itself!), if you know which one is running - or find out using "top". Afterwards you can jump back to gnome by pressing alt-F7 and (hopefully) you'll have the login window. cheers, Daniel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
