Description robinvanleeuwen 2011-05-22 01:41:24 UTC
When using the radeon driver i get a flicker of horizontal lines all over my screen. Running from top to bottom, see screenshot. I tried various kernel options:

radeon.new_pll=0 ---> solid black boot screen which stays solid black.
radeon.new_pll=0 radeon.disp_priority=2 ---> solid black boot , then
flickering black and then solid black again.
radeon.disp_priority=2 ---> normal boot but more flickering.

X -version
