This bug was fixed for me with the patch for bug #492392. (Which disables powersave for i915) There is no flicker and it runs stable for hours.
I tried out linux 2.6.33-020633rc5-generic from the kernel-ppa with i915.lvds_downclock=0. There was no flicker but it crashed (gray screen, but still able to login via ssh) after a few minutes, this time though I was able to get a batchbuffer dump. ** Attachment added: "dri_debug-20100123.tgz" http://launchpadlibrarian.net/38311055/dri_debug-20100123.tgz ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- [i945gm] [lucid] LCD "flashes" and jumps horizontally quite a lot https://bugs.launchpad.net/bugs/506444 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel 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
