12.04 boots to black screen ATI Radeon HD 3200

After upgrading from Oneiric to Ubuntu Precise booting ends up in a black screen with no whatsoever reaction. There is a short flicker showing the login screen before turning black, during which I can get to a login terminal via ctr+alt+f1. Already tried removing xorg.conf, uninstalling compiz, setting grub options to nomodeset or raden.modeset=0 , re-installing Xorg . Nothing would help.

Please help!

Thanks,
Alice

Seems to be a problem with the proprietary Drivers a.k.a. Catalyst/fglrx after upgrade.

Reached to a normal functioning login and laptop desktop by the following steps.
From command line mode which I could enter via Ctrl+ALT+F1 during the short flick of a purple background screen before everything freezes :

enabling restricted repositories, via manually adding to these lines to

/etc/apt/sources.list

deb http://us.archive.ubuntu.com/ubuntu/ precise main restricted

deb-src http://us.archive.ubuntu.com/ubuntu/ precise main restricted

(re-)installing Ubuntu-supplied fglrx/Catalyst

sudo apt-get update

sudo apt-get remove --purge fglrx*

sudo apt-get install fglrx fglrx-amdcccle

generating a new /etc/X11/xorg.conf file

sudo amdconfig --initial -f

Still, with that basic configuration dual screens would not work and graphics seem to be a bit upset, amd's catalyst center (gksudo amdcccle) keeps on crashing when hitting apply. The latter is a known bug under maverick as well, if there is no X11/xorg.conf file present, however, now catalyst seems to crash always)
