Okay, try this:
Modeline "800x600" 40.35 800 816 928 1040 600 600 606 626
Other things you need to know
(From /etc/XF86Config)
Section "Monitor"
Identifier "Primary-Monitor"
VendorName "!!! LCD !!!"
ModelName "SVGA 800X600@60HZ"
HorizSync 31.5-40
VertRefresh 58-62
The same specs will do for the video card. I am running the SVGA server and
have a rather puny Chips & Tech 65550
Make sure your HorizSynch & VertRefresh cover this area. (Both card and monitor)
This chunk is from /root/.X.err after starting X as root
(--) SVGA: chipset: ct65550
(**) SVGA: videoram: 1024k
(**) SVGA: Using 8 bpp, Depth 8, Color weight: 666
(--) SVGA: Maximum allowed dot-clock: 53.197 MHz
(**) SVGA: Mode "800x600": mode clock = 40.350
Make sure you have at least 40.35 Mhz in the dac
Set up /etc/XF86Config, & try it. check .X.err in your home directory and see
what went on. --
