Apparently, this bug is fixed upstream. Will it stay with 10.04 LTS users until the end?
Running v2.6.34-lucid is not a solution, because I want this computer to receive security updates. Using the stable kernel with radeon.modeset=0 is not an option either, because it complicates resolution changing.
Same problem with ATI Radeon X1200 (RS690M) on a DELL Inspiron 1526: external VGA display is flickering when running the stable kernel.
Booting the stable kernel with radeon.new_pll=0 changes the way it flickers, but the external screen stays unusable.
Booting http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v2.6.33. 5-lucid doesn't change anything.
Booting http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v2.6.34- lucid solves the problem.
