It might be your monitor. I've got an ATI Mach64 Graphics Ultra Pro or
something like that with Chrontel CH8398 RAMDAC and 1MB VRAM. On an old
is stretched vertically) with the card on the Mach64 X server, but not
with the SVGA server. However it worked fine on my Nokia 17" with both
vanilla vga monitor, did you?), which worked fine on a stone-age trident
card worked on the mach64 server but would not sync on the svga server.
But on the Mach64 server 720x540 was stretched, but 1024x768i was
NOT!!. These problems occured regardless of the bit depth.
Quite strange. Try a different monitor and see if the problem goes
away.
