I'm using Lubuntu 11.10. Every time I turn off my Sony Vaio I can read FAIL in red letters. But I can not read. I tried to take a photo, but not success.  Well, I was not worrying about this but today my laptop frozen during shutting down. I could read something about umount and other messages that I don't remember.So, how to read the log messages and try to discover/solve the  problem?
