Grabbing ModeLines from Xorg.log and setting them in xorg.conf won't work at
They are ignored. Modified config and logfile attached.

There is mode override in 'configure kdesktop / display'. But 'Apply settings
on KDE startup' is off.
If I set 1024x768 in xorg.conf and press ctrl+alt+backspace monitor switches to
that res.

Did I miss something?

Lucky I can change modes (and vsync) by xrandr tool.
1280x1024 at 60Hz - default, screen jumps only on user input,
1280x1024 at 72Hz - screen jumps without user input, sometimes stops,
1280x1024 at 75Hz - screen jumps all the time.

Underclocking video output might "solve" problem.
Is it a proper soltion?
