Bug#298472: [powerpc] Screen is flickering
Package: kernel-image-2.6.8-powerpc
Version: 2.6.8-11
Hardware: Apple Powerbook 1.5 GHz, 512 MB RAM, ATI Mobility Radeon 9600
128 MB
(lspci says: 0000:00:10.0 VGA compatible controller: ATI Technologies
Inc RV350 [Mobility Rad eon 9600 M10])
It seems to be impossible to configure X so that it isn't flickering at
all. Either you use 'append="video=ofonly"' in /etc/yaboot.conf in order
to avoid a slight horizontal flickering already visible in text mode,
then there's only a wild flickering when you start X, so that you can't
use X at all. Or you use 'append="video=radeonfb"' in order to make X
usable, but then this horizontal flickering remains also in the
graphical mode: There are kind of ghost images about 3 cm left to the
actual objects on the screen. With "ghost images" I mean: The objects
are drawn partially in some horizontal lines.
In kernels 2.6.9-1 and 2.6.10-3 this problem doesn't occur if you use
'append="video=radeonfb"' in /etc/yaboot.
Besides, the Debian installer should write the correct video mode into
yaboot, recognize the graphic chip and the screen resolution. I don't
know if it does now, but in November 2004 the sarge installer didn't.
