I'm running Linux Mint with LXDE on Dell Inspiron 1501. Whenever I issue poweroff command, or reboot or shutdown the computer via the graphical menus, it doesn't seem like a clean shutdown. In particular, on the next start, Firefox shows the annoying "This is embarrassing" message, and LibreOffice starts the "document recovery" process.
How do I investigate this problem?
ps) they are really closed before shutting down the machine.
