Crashing after login with graphic issues

view story

http://askubuntu.com – I am new to Ubuntu, and Linux operating systems in general, so I don't know much about anything, sorry. When I run Ubuntu, it runs well for about an hour and a half, and then disaster occurs. This seems to happen when I try to use the Ubuntu Dashboard (I believe that's what it's called, sorry). The desktop freezes for a few seconds, and then goes to a full screen terminal-like error screen (I don't know what it's called). It then says: Starting crash report submission daemon Checking battery state... Stopping System V runlevel compatibility [ 2506.860026] [drm] (I'm going of picture: did (HowTos)
