I cannot get the screen to blank in Ubuntu 14.04. I have set the lock screen to 1 minute. It never blanks. I have installed compiz manager and setup the unity plugin from info I read, this also does not help. I can type ctrl alt l to blank the screen which works. It then blanks properly after that until I reboot. Then it will not blank again.
Could some one please tell me how to get the screen to blank after a specified time when the system is idle like it used to pre 14.04. Thanks, Rob
