[Bug 455679] [NEW] "Lock screen" doesn't turn off TFT backlight

 

Public bug reported:

Binary package hint: xorg

When I click "lock screen" in the indicator-applet-session menu, my
screen is locked properly, but the TFT backlight isn't turned off.
Executing "xset dpms force off" in a terminal does turn the backlight
off though.
