Hi. Regarding my X-windows configuration problem, I was told > This information is readily available on the web: > > http://support.ap.dell.com/docs/monitors/p793/En/specs.htm > > Resolution > Horizontal scan range 30 kHz to 96 kHz (automatic) > Vertical scan range 50 Hz to 160 Hz (automatic) > Optimal preset resolution 1024 x 768 at 85 Hz > Highest preset resolution 1600 x 1200 at 75 Hz AFAICT, all this information is currently present in the xorg.conf file, except for the 85Hz. Currently, the xorg.conf file has Section "Monitor" Identifier "Monitor0" VendorName "DEL" ModelName "DELL P793" HorizSync 30.0 - 96.0 VertRefresh 50 - 160 Option "DPMS" EndSection Following the instructions in the xorg.conf manpage (as I understand them), I changed this to read Section "Monitor" Identifier "Monitor0" VendorName "DEL" ModelName "DELL P793" HorizSync 30.0 - 96.0 VertRefresh 50 - 160 Mode "1024x768" DotClock 85Hz EndMode Option "DPMS" EndSection When I ran Xorg, I got an error msg telling me that there was a parse error ("Unexpected token in verbose Mode entry) in this section. Just for fun, I tried changing the line to DotClock 85 (figuring that perhaps the "Hz" was the unexpected token). I got a different error msg, saying that the horizontal timings are missing. Obviously, I'm misinterpreting the manpage's instructions. Exactly how should I be specifying the 85Hz clock speed? HOWEVER ... I'm wondering if this is a red herring. After all, we're able to launch X windows successfully. The problem only happens when terminating an X windows session, in which case we're getting the abberant behavior: (1) The screen shows a floating box with a complaint. (2) When the X server shuts down, it wedges, and can only be restored by switiching runlevels (init 3; init 5). -- Art Werschulz (8-{)} "Metaphors be with you." -- bumper sticker GCS/M (GAT): d? -p+ c++ l u+(-) e--- m* s n+ h f g+ w+ t++ r- y?
