Looking for 17" TFT X11 config (mine is flickering...)

[Christian Hammers <ch@debian.org>]

Hello

My brand new LG "Flatron L1715S" TFT display with max resolution
1280x1024@75Hz and recommended resolution "1280x1024@60Hz" is flickering
like hell in the first and at least a bit in the second resolution.

A collegue of mine uses the same TFT with Windows and has, surprise,
no problems at all with 75Hz. I have just a "ATI 3D Rage IIC" but this
should be enough, or?

Can anybody give me a hint what to tune to get a clean picture?

thanks in advance,
