I am having this same problem and have been chasing the solution for a while. I have an RS690M chip in an intergrated X1200 card in my Toshiba Satellite A215 with TurionX2 64 chipset. I tried, in order: sudo gedit /etc/X11/xorg.conf and added the following line under the Section "Device": Option "AccelMethod" "XAA"
This virtually eliminated flickering, but it also eliminated the use of skype and cheese and other webcam-streaming apps, so I returned to the default xorg.conf configuration. So then I tried the updated: xserver-xorg-video-ati - 1:6.12.99 and xserver-xorg-video-radeon - 1:6.12.99 many people listed it as the fix for thier machines, but when it booted, I had a really fuzzy, bloated display that looked like it was 600x800 resolution, but no flickering. I would like to try it again and see if there is a way I can change resolution to match my screen (1280x800), becaue this seems like the best driver yet, no flicker at all. So I returned to the Jaunty default: xserver-xorg-video-ati - 1:6.12.2 and xserver-xorg-video-radeon - 1:6.12.2 and everything worked just as with the original install. Then I installed just the radeonhd 1.2.5 .deb package files, but without the full ubuntu-recommended installation guide (https://help.ubuntu.com/community/RadeonHD), just did a double click .deb package install. This changed nothing that I could tell, so I entered xorg.conf again and pointed it towards the radeonhd driver.... still can't tell a difference. lots of flicker, but still have skype and cheese webcam stream, just like the default. I am going through the steps to try the manual install of the radeonhd driver, but my hopes aren't very high. One question on this: do I need to purge the default radeon and ati 1:6.12.2 Any other suggestions on combinations of packages or advice on changing the resolution with the 1:6.12.99 package or something I may have missed? -- [RS690M] screen flickers when CPU is at low frequency https://bugs.launchpad.net/bugs/351291 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
