I had the same problem with an intel chips set. I found that creating a new xorg.conf file to help Xorg worked:
1. Determine the modeline(s) for your monitor.
Use http:// xtiming. sourceforge. net/cgi- bin/xtiming. pl
You may need to look at your monitor's manual, or, what worked best for me, was to google for my monitor. I was able to fill in enough details to get a usable modeline.
Modeline "1024x768@60" 64.56 1024 1056 1296 1328 768 783 791 807 +hsync -vsync
2. Turn off X11
$ sudo stop kdm
3. Reconfigure X11
In a virtual terminal, log in and:
$ cd /etc/X11
$ # backup existing xorg.conf file if exists
$ sudo mv xorg.conf xorg.conf.20091031 # xorg.conf may not exist
$ sudo Xorg -configure
$ sudo mv xorg.conf.new xorg.conf
In the section "Monitor", add the mode line:
Section "Monitor"
# keep other lines here
Modeline "1024x768@60" 64.56 1024 1056 1296 1328 768 783 791 807 +hsync -vsync
EndSection
And under the "Screen" section, add a reference to your new modeline:
Section "Screen"
Viewport 0 0
# keep other lines here
SubSection "Display"
Modes "1024x768@60"
Depth 24
EndSubSection
4. Restart Xorg
$ sudo start kdm
5. Parting thoughts
a) This is an annoying regression. 9.04 did not have this problem with Intel graphics.
b) The +hsync and -vsync options were trial and error. If you find horizontal blurring, trying +hsync
c) Remember, your modeline is resolution and monitor dependent! Take care with step 1
I hope this helps!
