I've tried rebooting the machine as well as a complete shutdown and still get the same thing. When I try different resolutions (1024x768, 1280x962, etc) the overlaop goes away. Should I check into setting the vertical sync rate and , if so, how do I know what is the right one for my monitor?

Hi all,
I've been working in XFree86 4.3 on Debian for a while with no problems. I opted to change my system time using the clock panel thingy and upon saving my changes, the screen went off then on again and I have an overlap at the bottom of the screen that is a copy of the first 10-15 pixels of the top of the screen. I'm running at 1280x1024. When I switch to 1024x768, the problem doesn't show. I've tried adjusting the monitor but there are useful things, namely the status bar, behind that overlap. Any thoughts??
I believe that these lines in the logfile:
GetModeLine - scrn: 0 clock: 108000 GetModeLine - hdsp: 1280 hbeg: 1328 hend: 1440 httl: 1688 vdsp: 1024 vbeg: 1025 vend: 1028 vttl: 1066 flags: 5 GetModeLine - scrn: 0 clock: 108000 GetModeLine - hdsp: 1280 hbeg: 1328 hend: 1440 httl: 1688 vdsp: 1024 vbeg: 1025 vend: 1028 vttl: 1066 flags: 5 GetModeLine - scrn: 0 clock: 108000 GetModeLine - hdsp: 1280 hbeg: 1328 hend: 1440 httl: 1688 vdsp: 1024 vbeg: 1025 vend: 1028 vttl: 1066 flags: 5
indicates that some application explicitly changed the modeline through the XF86VidMode extension. One app that I know of that does this is X-Screensaver. My guess is that when you changed your system time, there was some confusion about when the screensaver should come on and the screensaver came on and switched modelines somehow. I assume that quiting and restarting X resolves this problem?
