After Laptop (ASUS N76 VZ) wake up from sleep, Laptop-Screen keeps black. Reproducible: Always I have checkd the Syslogs and find out, powerdevil set Backlight to 0 for sleep. Then I've tryed to push FN+Brightness up, and the screen gets visible again... So may be a bug, that powerdevil not set the Backlight back to value which was set before Laptop go to sleep.
