Bug#457612: xserver-xorg-video-ati: x fails after update on testing. ppc ati 7500 graphics card

[LeeE]

I'd like to add that I'm getting the same problem as oswaldkelso 
except that I'm on i386 and not ppc and the card is an ATI 9200 
(RV280).  I can boot the system in to a back up 'etch' install 
where it works ok.

To summarise:

Xorg appears to load and run ok but the screen remains blank.  If I 
leave the system alone i.e. not touching the mouse or keyboard I 
can see the monitor switch into standby and then if I hit a key or 
move the mouse the monitor comes back out of standby but the screen 
remains blank.

When booting the system from an Ubuntu 8 cd for a live session I can 
hear the session start-up sounds, indicating that xorg thinks it's 
working ok.  If I then Ctrl+Alt+Backspace to kill X I hear the 
session startup sounds again, as x reloads.

A curious thing I've noticed is that when X thinks it's running ok 
it's not possible to use the screen (A Philips 109s CRT monitor) 
OSD controls to change brightness, contrast etc. - the OSD controls 
do not appear on the screen, but they do appear ok when back in the 
console or when etch is running.

Running with DPMS disabled made no difference - it does not seem to 
be possible to disable EDID with the xorg ati driver.

I've also tried several different kernel versions, with no change.

Please let me know if you want the xorg conf & log, but they don't 
seem to show anything relevent - as I say, xorg seems to think that 
it's running ok.
