I've been using xscreensaver for some time now, with no trouble. I could easily let my box go without rebooting for over a week at a time. Recently, I got a new nVidea card with 128meg RAM. I had no problems getting the drivers installed, and soon switched over from metacity to compiz. Now, several times a day, the computer doesn't come back properly from the screensaver. I have a mouse cursor, but it's in front of the last image the screensaver showed and my hard disk light is constantly lit. Sometimes, I can use Ctrl-Alt-F2 to get to another screen and log in as root. Using top, there's no obvious reason for this. If I kill Xorg, I can go back to my original screen and restart the server, but of course, that logs me out. Killing compiz isn't quite as drastic, but once my session comes up, I can't actually do anything, so I end up logging out and back in anyway. (Once in a while, I have to do that twice, because the first time I don't get any icons.) At least once a day, i have to reboot my computer to get control back, and if I wanted to reboot that often, I'd have stuck with Windows, wouldn't I? Has anybody else seen this or have any suggestions. (Please, don't suggest hardware upgrades, as I'm unemployed and broke; the new card was a gift.) Oh: before I forget, I'm running Fedora 9 and have all the latest updates.
