Hi all,






I have installed Ubuntu 12.04 with Cinnamon.

After a while I had a hang of the system and I couldn't use the keyboard and mouse and had to hard reset the machine. Immediately after that I had an error message that said I was working in low graphics mode, I tried fixing it with the xorg.conf file but no luck.

I had uninstalled Cinnamon, and reinstalled my ATI driver but now I'm on Unity with the computer seeing only one screen of two and in the resolution of the second one (since they are duplicated).
I also disabled the screensaver, but still the screen goes blank after about 10 min. I tried to remove the cinnamon packages I see with dpkg but I get a message that they are not installed and nothing to remove.
I booted the computer to recovery mode and ran the dpkg entry in order to try and fix any broken packages, no luck.

How can I fix my computer? I would like not to reinstall but to fix the problem.
If I have to reinstall the system, what configuration files should I save other than fstab, smb.conf and mdadm.conf?
