does the "lock screen after" option not work for anyone else in f18? Even if I set it to 30 mins or one hour it locks the screen right after the screen turns off (10 mins)
I did have one annoying problem with kernel 3.7, I had a powersave script that does various tweaks to save power on battery. one of those tweaks is disabling the NMI watchdog on battery. With kernel 3.7 disabling nmi watchdog just causes a complete system freeze lol.
