The behaviour is that I stand up from my machine, and comeback a couple of hours later (desktop machine, no sleep or hibernation involved). When I come back it's unresponsive. It doesn't provide signal to the monitor, the keyboard "numlock light" doesn't even work.
However I can ssh into it just fine, and work just fine inside. But no graphic system, and no way to really restart any process to get it back (everything I tried, at least).
I normally end up issuing a `sudo shutdown now` (after sshing inside), which makes it work a while but DO NOT turn the machine off (it looks that whatever is hung prevents that).
