Public bug reported: Binary package hint: xserver-xorg-video-ati
On maverick with KMS enabled, programs that use video "fading" effect are unusably slow, screen updates "freeze" for seconds with X server using 100% CPU. Easy way to demonstrate it is to view this slideshow with Firefox: http://www.electricprism.com/aeron/slideshow/example1.html The problem is also apparent with other programs like F-Spot's slideshow, and is observable on different hardware with different models of Radeon adapters. The effect disappears if you disable KMS (by adding "radeon.modeset=0" to the kernel command line). Reported to xorg team https://bugs.freedesktop.org/show_bug.cgi?id=30872 and it turns out that the problem is fixed in newer versions of the driver. It does happen when running default 1:6.13.1-1ubuntu5 version but does not happen with the version from xorg-edgers PPA 1:6.13.99+git20101012.0d1f9fd0-0ubuntu0sarvatt. ** Affects: xserver-xorg-video-ati (Ubuntu) Importance: Undecided Status: New -- Fading effect slow with KMS in maverick https://bugs.launchpad.net/bugs/660999 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
