I run Ubuntu 10.04 inside VMware on a windows host. After a power outage I can no longer log into Ubuntu. I get to the login screen, which mysteriously also changed its color theme from the standard ubuntu theme to some bluish theme. When I type in my password. It seems to do something, the screen turns black a cursor appears for a second but then it returns to the login screen. In the upper right corner appears a error message:
INSTALL PROBLEM! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator.
Just to be clear, if I type in the wrong password, I get the regular Authentication failure error. Any ideas of what's going on? How could I save the system?
