Hi,

I have been playing with dual monitor and most things work except for some
strange things...

config: Athlon 1600+ with Asus V7700 GeForce2 GTS AGP and some S3Virge DX
pci. Slackware 10.1/2.6.13 (home brewed)

When I run X on just one of both cards, it works perfectly. When I config
the second one, the S3 behaves strange: - at aprox 2 inches from the left,
a white vertical line appears, while the leftmost pixel column turns
purple. - white horizontal distortions flicker up and down. - mouse cursor
has strange block, sized 4x4 as if on 80x25 textmode. graphical cursor is
placed top right, while effective pointer is top left of that block
- CMYK map is turned 120 degrees clockwise. i.e. red is turned green

monitor on the s3 is a Trust Precision Viewer 17" but configured
perfectly; it can handle 1280x1024@85 and it runs at only 1024x768 A
search in the archives of this newsgroup resulted in adding Option
"ShadowFB" "on" and Option "SyncOnGreen" with no results...

Below the most interesting parts of xorg.conf
