I have an S3 Trio3D with 2MB vram. It should be able to display 24bit at 1024x768 (it does in Win '98) but my X Window manager will only run at 640x480 and 256 colours.
Fiddling with /etc/XF86Config doesn't seem to help. I've also tried re-installing.
How can i make the resolution and colour depth higher?
