GNOME Power Manager: install problem

In the upper right corner of my login screen, I get the following error in Ubuntu:

INSTALL PROBLEM! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator.

When I type in my password. It seems to do something, the screen turns black and a cursor appears for a second but then it returns to the login screen. The theme also appears to be bluish.

I noticed that this is more related to my hard disk memory reaching its limits.

So I followed the following steps:

  • Start the computer
  • On the login screen, press CTRL+ALT+F1. This will take you to the command line
  • Login with your username and password
  • Check the disk usage using the following command: df -h
  • Clear some space by deleting a directory that you do not need. It has to be a big directory, say 1GB. In my case, I used the following command: rm -vR /home/frank/very_big_dir
  • Then reboot: sudo reboot.
Hopefully, this should have fixed your problem
