I am using the standard opensuse ati driver called "radeon".
I've been using this driver for several years with the same card
but with an 17" CRT monitor with resolution 1024x768. I
never experienced any problem with it.

My TFT is set according to the manufacturer's instructions (20"
monitor, 1400x1050 at 60 Hz. The only thing I can think of
that the graphics card is not powerful enough for changing the
screen fast. I don't think it is trying to change resolution.

I will try the monitor with another more powerful card.

I doubt a "more powerful" card is a good solution to your problem. My 20"
Viewsonic LCD is 1400x1050@60. When I first got it 2 years ago I was using a
4MB Tseng PCI card designed in 1996. It gave no problem in framebuffer, DOS
or OS/2, but did for a time have a problem in Mandriva's X that eventually
got fixed:

Will yours work OK if you boot a Knoppix CD? Have you tried commenting out
the UseModes line in xorg.conf?


Also, don't forget you can use the gtf utility to create a custom mode
line to
use in your xorg.conf:

01:30 alchemy~> gtf

usage: gtf x y refresh [-v|--verbose] [-f|--fbmode] [-x|--xorgmode]

x : the desired horizontal resolution (required)
y : the desired vertical resolution (required)
refresh : the desired refresh rate (required)
-v|--verbose : enable verbose printouts (traces each step of the computation)
-f|--fbmode : output an fbset(8)-style mode description
-x|--xorgmode : output an Xorg-style mode description (this is the default
if no mode description is requested)
