After I updated my 12.04.3 installation yesterday normal Unity didnt show up. It keeps falling back to Unity2D.

Also /usr/lib/nux/unity_support_test -p says my graphic card AMD Radeon HD 6700 Series is not supported but is used to work for over a year. It maybe that some recent changes to unity package broke something.

Update history: http://paste.ubuntu.com/6727763/

I have tried doing this:

sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

But now LightDM ist even starting. How to repair it to usable state?

Solution was easy: This will remove proprietary driver and install Open Source one. 

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

Remove your xorg.conf file

sudo rm /etc/X11/xorg.conf

Re-install xorg

sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core

Configure xorg

sudo dpkg-reconfigure xserver-xorg

Reboot:

sudo reboot

Now you can install proprietary driver again. Cheers!
