I've had this problem on and off for awhile with a sid box. WindowMaker is my window manager, but the same problem occurs when I run any other manager. I first noticed that when I run the Gnome Control Panel X reboots back to kdm. Based on scouring the internet I narrowed it down to screensaver-properties-capplet. It seems to be the program that causes X to reboot.
My video card is a NVidia TNT2. I have a custom compiled kernel. I have tried the following steps to no avail: - Deleted all my user gnome config files - Uninstalled and reinstalled xscreensaver. Note that the screensavers seem to work, although I've seen a 3D one crash. - Switched to mesag3 instead of xlibmesa... (Which is better?) - Needed to get the xscreensaver daemon to start automatically. Fixing that didn't help. I have the tail end of an strace at the bottom. Please let me know what additional info would help diagnose the problem.
