Same symptoms and the kernel parameters "radeon.modeset=0 vga=771" also fixed it finally, whereas "radeon.new_pll=0" alone did not help (another dozen of googled suggestions failed too. So many thanks for this hint!) My graphics adapter: 01:00.0 VGA compatible controller: ATI Technologies Inc M24 1P [Radeon Mobility X600] I use Ubuntu Lucid with kernel 2.6.35-23 and disabled KMS ever since, because with KMS overlay video playback is not possible anymore and textured video playback shows artifact (looks like a diagonal edge of an OpenGL triangle not drawn correctly synchronized with vsync. But thats another bug...). If I can help with further data or tests, then please just ask. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
