Hello,
I have installed the OS updates from Ubuntu software center. When I login on my laptop after ~minute the display is dimming to 50% then 100% and can do nothing about it.
When I have a second monitor coected to my laptop (mirroring or extended desktop) the same thing happens with my laptop monitor, but the exteal monitor is working.
Any help? Can't find a solution on google.
Ubuntu 16.04LTS
Graphics: Intel iris 540
