I'm trying to get an ATI AIW X1900 to work with a Syntax LT37HVS LCD (http://secure.syntaxgroups.com/produ...sp?pid=LT37HVS) on Ubuntu 6.06.1. I can get the video to work at various resolutions and get ~9000 fps with glxgears. The problem is that I can't get the desktop to fill the entire screen i.e., there is a black band around all the edges. Iff I change the resolution to 1920x1080 (in xorg.conf) then it uses the full screen, but the desktop is larger than the screen i.e., I'm missing content from around all the edges.

I can use an MSI K8NGM2-FID based on Nvidia 6150 chipset and it fills up the screen at 1280x720 resolution with this modeline:

Code:

ModeLine       "1280x720_60.00" 74.5 1280 1336 1472 1664 720 721 724 746 -hsync +vsync

Using this modeline (full xorg.conf below) with the X1900 ends up with resolution at 1152x648x60. I can change the resolution using "screen-resolution" within gnome. If I change it to 1920x1080x30 I end up with the desktop being cut off around the edges.

I'm using:
linux-restricted-modules-2.6.15-26-amd64-k8 2.6.15.11-3
xorg-driver-fglrx 7.0.0-8.25.18+2.6.15.11-3
