I am new to using Linux, although I like using it so far. Today, I was installing several programs from the Ubuntu software installation center, and I received a message that my disk drive was nearly full. So, I stopped the installations that were running, and continued to use Ubuntu for the rest of the session. However, when I turned off my computer and tried to reboot, I get a different login prompt, and in the upper right corner, the following message is displayed:
Install Problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator.
When I enter my login password, it then goes to a black screen, and reloads exactly what I just described above. I tried to run Ubuntu in recovery mode, and selected the third option on the recovery menu (I think it said restore installations), but that did not fix the problem. Does anyone know how to fix this without having to reinstall Ubuntu? Any help would be appreciated. Thank you.
