fglrx does not work with Radeon HD 6600M in Ubuntu 12.10 (EFI mode)

[jhjkgfd6]

I am unable to get working video on my MacBook Pro 8,2 with a Radeon HD 6600M running Ubuntu 12.10 (Quantal Quetzel). I attempted to install the driver (2:9.000-0ubuntu3) in the following manner:

sudo apt-get --purge remove fglrx*
sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install fglrx fglrx-amdcccle
sudo aticonfig --initial -f

When I complete the last step part of the output is:
PowerXpress info: Diagnostic output from /usr/lib/fglrx/switchlibglx:
update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken
update alternatives: warning: not replacing /usr/lib/x86_64-linux-gnu/xorg/extra-modules with a link

When I rebooted, I was forced to use low-graphics mode. I expected to boot into Unity with graphics. It is worth noting that this problem occurs in EFI mode. When I boot in BIOS mode, Unity does start. However there are still periodic xorg crashes.

Same problem here.

Status changed to 'Confirmed' because the bug affects multiple users.

For UEFI support, you can download latest Catalyst Linux driver from AMD website. The 9.00 fglrx driver in Ubuntu archive doesn't have this support.
