Hi,
I am trying to configure my X system for noninterlaced 75MHz refresh at
1024x768? I was told before that to change the refresh I need to change the
clock frequency. I am currently configured for 1024x758 interlaced, I do
not know the current refresh. I know my video card and moniter can handle
it in noninterlaced mode, that is how in runs in win95. Currently my
XF86Config files lookes like this:

HorizSync      31.5, 35.15, 35.5
VertRefresh    55-90
Modeline       "1024x768"     44.90  1024  1088  1248  1264  768  772  780 
829  interlace

I have tried just removing the word interlace, but then I get the following
messages:

(--)  S3: Maximum allowed dot clock: 220.00 MHz
(--)  S3: There is no mode definition named "1024x768"
(--)  S3: Removing mode "1024x768" from list of valid modes

I think I need to change the clock frequency as well as removing the word
"interlace" from XF86Config, my video card is a STB Velocity 3D with 8mb of
RAM.

Thanks!
Daniel Keller

PS:
Thanks to Robert Eckardt and everybody else who helped me last time I was
triyng to figure this out.
