Messed up rendering

Hello all
Since the 11.10 release of Ubuntu, and now the 12.04 release of Ubuntu, my
Radeon HD 6970 has not worked properly with the open source drivers. It always
boots up with the corrupted screens as shown in the pictures below. My display
setup is a bit unusual; I have a 1280x1024 analog display that I have plugged
in to the graphics card via a DVI-to-VGA adapter (also shown below). These
problems do not occur if I use the proprietary driver suite or if I use Windows
7.
Thanks in advance.

It could be the same bug as I reported a while ago Bug 43655. Could you try one
of the two following options:
- under grub.cfg, remove "set gfxpayload=$linux_gfx_mode" for the problematic
boot entry.
- under grub, when you boot, select a different entry. Usually, with Grub2
under Ubuntu, you'll find the same boot entry in your list at the bottom, but
it doesn't use the "set gfxpay..."

Read bug 43655, it could give you a hint. If it does help, then you'll be
welcome aboard. ;)

Alexandre:
Thank you! Removing that line from my GRUB config file solved the problem!
I guess someone should mark this as a duplicate of Bug 43655 now.
