Description of problem:
From the time I installed RH8 on my Dell Dimension 8200 I've gotten warnings
about "xscreensaver-demo" not found, perhaps because of some .cshrc path wierdness
So yesterday I decided to run it from the command prompt. Big mistake. It seemed
to come up ok, I configured it, noticed dpms was not enabled, and enabled it.
Now whenever the screensaver comes on my display goes unrecoverably haywire. I'm
running at 1400x1050 on a GDM-5510 monitor. The display divides into about 32
equally spaced horizontal slices and every other one seems to be offset by some
degree. Moving the mouse doesn't do anything. I have to log out and in again to
reset. When I try the "cntrl-alt-f1" trick the screen goes to sleep and I can't
get it back without rebooting. As you can imagine, this is driving me nuts.
Also, if I do an xset -dpms to try to turn off dpms, that causes it to go
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.run "xset -dpms"
More info: disabling the screensaver in xscreensaver-demo didn't help.
Here are some salient bits from my X config. Nothing in this has changed in a while.
VendorName "Monitor Vendor"
HorizSync 30.0 - 130.0
VertRefresh 48.0 - 170.0
# no known options
Identifier "NVIDIA GeForce 2 MX (generic)"
VendorName "NVIDIA GeForce 2 MX (generic)"
BoardName "NVIDIA GeForce 2 MX (generic)"
Device "NVIDIA GeForce 2 MX (generic)"
Modes "1400x1050" "1280x1024" "1280x960" "1152x864" "1024x768
" "800x600" "640x480"
I commented out the load "dri" and "dpms" option lines and this seems to make
the problem go away...at least, I can't reproduce it immediately with the "xset
-dpms" like I used to.
I determined that the commenting of the "dpms" option was sufficient.
Resetting the Xserver does clear the problem, but of course then I lose my
session and any unsaved work.
