[Xorg-driver-ati] Bug#389017: reopen 389017

reopen 389017

This bug was closed without solution.

Please note that with the OP's 

"ATI Technologies, Inc. RV350 [Mobility Radeon 9600 M10"

it indeed should be possible to use the UseFBDev in xorg.conf if using a
version of xserver-xorg-video-ati other than the one that now seems to
be broken. The machine where this works with a different version also
is a PPC Powerbook. Details below.


Following a few snippets from the local xorg.conf that does not crash
X on the hardware mentioned further down below, when using a patched
version [Please see #369167 for more on it], namely
xserver-xorg-video-ati 6.5.8.0-1

And here's the hardware where "UseFBDev" works:

$ lspci -v | grep -i radeon
0000:00:10.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Rad
eon 9600 M10] (prog-if 00 [VGA])

For the sake of completeness:

Please note that even with the working 
xserver-xorg-video-ati 6.5.8.0-1 
I occasionally have the problem when booting the machine or
when switching, IIRC, from X to a console, that the screen gets
unreadable, with nothing on it than a changing mix of colors. It's
looking like a sixties' lightshow then, like the ones seen on rock
concerts at that time. Hard to describe. But simply getting the
machine into sleep mode, and waking it up again, solves this, IIRC.

Also please note that I want to upgrade as soon as possible to this,
as it seems, broken version of xserver-xorg-video-ati. I will delay
the upgrade if you think the old, now running version might help to
debug this issue. Again: Seeing #369167 might help ....

Thanks for your efforts

Best Regards
Wolfgang
