fglrx - X desktop is garbled on Radeon Mobility X1400

[Adam Johnson]

Binary package hint: xorg-driver-fglrx

This problem occurs with package:

xorg-driver-fglrx 2:8.600-0ubuntu2 (jaunty)

After installing this package I can't get to the X desktop; the screen is garbled. More specifically it looks like the screen is rendering but each raster is offset (stair-stepping, like the rendered buffer pitch is wrong).

I'm gonna take a wild stab in the dark and say one of the following is happening:

- The desktop is rendering in a different pixel format to scan out.
- The primary render target size is wrong.
- The primary render target pitch is wrong.

Also worth noting is that X is 'working'; I can still interact and shut the machine down. I can even see the desktop trying to render but it looks like a total mess up at the top of the screen with some random memory junk at the bottom. I'm running on a Dell Inspiron 9400 with a Radeon Mobility X1400.

I've also tried to get a screenshot; obviously I can't do this from the desktop so I had to break out the trusty camera (apologies for the blurriness).

I am fairly certain that I am also affected by this bug. I'm on a Lenovo Thinkpad T60 that came with the same card. No drivers are listed in Hardware Drivers, and I tried to install fglrx to get hardware accel working. Screen was garbled beyond recognition.

This page seems to suggest that it worked at some point: https://wiki.ubuntu.com/LaptopTestingTeam/ThinkpadT60-5BU

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
