View Full Version : [ubuntu] Laptop screen blanks but backlight is still on

July 29th, 2009, 06:57 AM
I am running Ubuntu 9.04. In System > Power Management Preferences I have set the display to be put to sleep when inactive for 5 minutes. But after 5 minutes of inactivity the screen is blank (black colour screen) but the backlight is still on. On my desktop the LCD screen is completely off and the indication LED switch to standby (orange). However if I run this command "xset dpms force off" the backlight is off. Any idea?
