When I open dark dark applications my screen changes brightness automatically.
How can I disable this feature?
I have already un-checked the following options for battery and AC power:
- Reduce backlight brightness.
- Dim display when idle
My brightness is set to 100%
However, I am still getting the same behaviour.
My Laptop is: Dell Inspiron 14 5447
My OS is: Ubuntu MATE 16.04
My graphic card is hybrid (Intel+ATI)
From Additional Drivers Unknown: Unknown is installed and it is (a proprietary) one
Any help is appreciated.
