** Summary changed: - [ati radeon rv280] Screen displays horizontal streaking, mouse cursor normal with AGPx8; worked okay with Feisty + Blank screen or distorted image because of wrong default AGPMode value
** Description changed: Binary package hint: xserver-xorg-video-ati Since the updates a few days ago on gutsy, my screen shows horizontal tearing streaks with only the mouse pointer shown normally (see http://launchpadlibrarian.net/9255354/00001.jpg). This is on a radeon 9250. Usplash is displayed normally, gdm and gnome are scrambled. This problem was first seen on Gutsy with the upload of the 1:6.6.193-1ubuntu1 ati driver, and worked fine on Feisty and Breezy. Downgrading xserver-xorg-video-ati to feisty's 1:6.6.3-2ubuntu6 fixes the problem for me, so the problem must be in the changes between that version and 1:6.6.193-1ubuntu1.
