I lowered the brightness until the point there the backlight is completely off, and after X minutes I wanted to turn the screen again by using the function keys to increase the brightness, but they weren't responding. After a while I realized the screen was blocked, so I blindly type the password, pressed enter and then used the function keys to increase the brightness and it worked. I think it will be much better if one can change the brightness of the screen even if the screen is locked. I can't see any security problems in allowing that. Optionally, it would be nice if the user can set his lock screen to allow changing the sound volume and other slightly harmless activities one can do with the function or multimedia keys while the screen is locked (is a common thing in the mobile world, I think).
