Since last week, my screen in ubuntu 16.04 keeps dimming even while I am active. I unchecked the dim screen to save power tickmark in the lock and screen settings, and I am running on AC power too. Nevertheless the screen dims every minute or so (I set the limit to 30 minutes but it should never dim). It dims even while I am typing or scrolling with the mouse.

Anyone having an idea why the settings do not work suddenly?


Having similar trouble. Screen blanks out if the mouse or keyboard are idle for less than 10 seconds!

Anyone see behavior like this?
