Nothing works anymore. Going to terminal mode (Ctrl-Alt-1 to 4) shows a black screen. Going back to X mode (Ctrl-Alt-7) does not work either. After that, only pwoer off and a restart helps. I took a look into kern.log and syslog.log (both attached) and found the following lines, maybe, they are related to that.
