I hope you can help me with an annoying problem that just crept up.
A couple of days ago I reinstalled Mint 7 on a Dell Latitude 6300. System is fully updated, not a lot of stuff installed (most notably Virtualbox, some small stuff, no desktop candy whatsoever). Since then it has happened already half a dozen times that the desktop completely freezes. Mouse pointer can be moved, programs seem to continue to run (music plays on), changing volume and screen brightness with laptop function keys is also ok - but nothing else. No input is accepted, neither ctrl+alt+backspace nor REIBUS work. I can only go for a hard reset.
I've checked the log files but didn't see anything interesting.
Before I reinstalled Mint, I ran a Mint/Vista dual boot combo on the same laptop. I never encountered this problem, so I doubt it's hardware related.
Let me know what kind of info you need.
Any ideas appereciated,
