about 1 times of 10 the system answer in the correct mode (logout, turn-off or reboot)
about 5 times of 10 the gnome menu hangs after the "end session" options (so i must use the power button , and with it the system goes off correctly: i see all the turn-off messages)
about 4 times of 10 i can choose the "end session" option, i see the various options (logout, turn-off and reboot) but when i click "ok" the screen goes black and still black (i must use the power button , and with it the system goes off correctly)
any idea?
thx
(sorry for the eng..)
