Setting limits on screen brightness maximum and minimum
When my laptop starts and I start an X session with Mate, the screen brightness "jumps" up, but the level on the indicator remains the same. This is concerning as it sometimes brings the brightness to levels that I am sure are not healthy for the screen.
So, is there a way to hard set limits, or a range of possible brightness values?
Alternatively, if anybody else has experienced this and knows of a cause and/or solution, it would be great of you could share.
If it is any help, I have a ThinkPad T420 with the Intel graphics.
