Any help is greatly appreciated. Thanks.

I read few posts from this topic and found solution. The problem was traditionally with direct rendering. I made some changes in /etc/X11/Xsession.d/10fglrx. Now it looks:
Code:
LIBGL_DRIVERS_PATH=/usr/lib/fglrx/dri
if [ `uname -m` = 'i686' ]; then
  if [ -d /usr/lib/fglrx/dri ]; then
    LIBGL_DRIVERS_PATH=${LIBGL_DRIVERS_PATH}:/dri:/usr/lib/i386-linux-gnu/dri
    if [ ! -z $LD_LIBRARY_PATH ]; then
    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:
    fi
    LD_LIBRARY_PATH=${LD_LIBRARY_PATH}/usr/lib32
    export LD_LIBRARY_PATH
  fi
fi
export LIBGL_DRIVERS_PATH
And direct rendering works fine. If you still have this problem just check what gives "uname -m" and locate file 915_dri.so.
Please, read my post #356. Your changes can work, but isn't the best method.

And even though this might not be directly related to the topic at hand: Can I reinstall Ubuntu without compromising my Windows installation?

Thank you very much in advance.

P.S.: First post on the Ubuntu forums, yay. (albeit not my very first one, to tell the truth; just forgot the login details on another account)
If something got wrong in video driver installation, you just need to delete xorg.conf file in /etc/X11/ and reboot
so, run this command:
Code:
sudo rm -f /etc/X11/xorg.conf

You probably is using wrong package for your architecture. If you are using Ubuntu 64 bits you should download 64bits packages (amd64, even for intel processors). If you are using Ubuntu x86 you must download x86 packages. Just try again fixing it.
