Does anyone know how to deactivate the automatic brightness control?
I am using gnome 3.24.2 and kernel 4.12.8-2. The gnome settings -> Energy -> Dim during inactivity is set to off. There are no laptop tool installed that could control this.
Never the less after a time the brightness of the display is reduced.

You question is too vague. Some laptop have an ambient light sensor and adjust the backlight accordingly. Is it that you are talking about? There is a post there https://possiblelossofprecision.net/?p=1537 for the HP elitebook 2560p but maybe you can try to ind a similar file on other laptop. Also that feature can be disabled in the BIOS.
Some desktop environment dim the display when the battery is low or other things like that. I do not know Gnome. In xfce the is a Power manager setting where you can set this. Maybe there is something similar in Gnome?
