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 "1024x...@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 "1024x...@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" # keep other lines here SubSection "Display" Modes "1024x...@60" Viewport 0 0 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! -- Screen resolution only 800x600 on Karmic after installation on ASUS EeeTop 1602C https://bugs.launchpad.net/bugs/466880 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
