hi I have just installed ubuntu 7.10 i had a problem in startup log in screen. It said: Can't open file /usr/share/gdm/themes/Human/Human.xml i changed the theme and the error is gone. However, once i login, the theme is still the previous one. My desktop doesnt show any files and it looks empty Moreover, I cant access any folder from GUI mode, can access them only from terminal. are these problems related to each other? any idea how to fix it?
