Bug Description
Binary package hint: xserver-
Ubuntu Lucid with ATI FireGl 8800 card (r200 chip).
lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R200 QH [Radeon 8500] (rev 80)
My monitor model is an HP p1120
-HorizSync 30-121
-VertRefresh 48-160
Since I installed intrepid I have a temblor in my monitor (In the other Ubuntu releases it works great). It is especially visible at the edges of the windows.
It is very strange because all seems to be correct (with the default xorg.conf configuration):
- Resultion is on the default 1600x1200
- The vertical refresh rate is on the default 85Hz
- The horizontal refresh rate is on 106.3kHz
I try to configure the HorizSync and VertRefresh manually editing the /etc/X11/xorg.conf file but nothing changes
The tremor is only in 1600x1200 resolution.
The others resolutions works well
In Windows with the same settings (1600x1200 - 106.3kHz/85Hz) there is no tremor

Thanks for your bug report. Would you be able to attach a log from a Ubuntu release where it worked fine?
This could be a problem with calculated PLL values, AFAIK.
