I can confirm a similar problem with ATI Radeon 9600.

If the graphic card driver is set to "ati" i get a blank screen - nothing works (that I know of) to regain control of the machine except the power button.

When I change the driver to "fbdev" it works.

I attach a tar file with
:. Xorg.0.log-ati
:. Xorg.0.log-fbdev
:. lspci-vvnn.txt
:. dmesg.log
:. uname-a.txt
:. xorg.conf

Paddy.

I no longer have a hang. paddy: is it working for you now too?

Sorry to say - I still have the same problem.

I just changed fbdev with ati in the xorg.conf file and restarted X - black screen. I could not regain control of the machine and had to power cycle.

I am glad to see that your problem has been resolved.

I am performing a update/upgrade as I write but I don't see any X related updated. I will try again later all the same.

Paddy.

Problem is solved!!

I understand that this is a feature that is added to the radeon driver by debian/ubuntu team(s). The code does not cater for ppc users and the driver tries to find/load an x86 bios even on a ppc machine.

The solution you may ask? Add the following to the ATI driver section
    Option "noint10" "yes"

Please find attached my xorg.conf file.

Any now even Beryl works like a dream.... and glxgears gives
6240 frames in 5.0 seconds = 1247.842 FPS
6435 frames in 5.0 seconds = 1286.823 FPS
6360 frames in 5.0 seconds = 1271.958 FPS
6508 frames in 5.0 seconds = 1301.523 FPS
6436 frames in 5.0 seconds = 1287.071 FPS

and I was getting over 1800 FPS too at one point :-)

The original bug has been fixed in feisty, so I'll close this one.

Paddy, your bug is #93509.
