I've found a very strange behaviour of my system: GUI sometimes freezes.
Test case is:
1. Plug AC adapter. Screen brightness is increased. (BTW how to make brightness
is not changed?)
2. Change brightness with keyboard (e.g. increase or decrease)
3. Try to press on any Ubuntu menu (e.g. System, Applications). This menu is
only highlighted but is not opened (pulled?). I cannot open menu for system
shutdown either.
4. Restart X by pressing Ctrl+Alt+BkSpace.
5. System is working fine.
6. Try again (or simply change brightness). System will freezes again.
Sometimes I cannot reproduce this bug (after 2 or 3 times of doing this test)
but it is on my system.
Next message I'll attach some logs may be someone find something in them.
