Hi guys.
I have arch running on my laptop with gnome3.
The display is dimmed after few seconds that I'm not active. Very often, I'm reading text or staring my code on my machine and this is annoying. Power management doesn't have any option to cancel this.
How can I manipulate this?

Check out Settings -> Screen and uncheck dimming.
Although it didnt work for me :
I personnally chose tu use laptop-mode-tools (see wiki) on my T420 to control the brightness. It works nicely BUT and here is the thing: Gnome keeps dimming my brightness anyway even if I unchecked this. In dconf-editor under org.gnome.powermanager there is no option.
I do remember Gnome 3.0 having options in dconf-editor to deactivate display dimming and leave it to hardware.
Sorry for not being able to help. I actually wanted to post a thread about this but I saw yours and it seemed related.

Hum. Weird. I played with some settings. Checked 'Dim the screen' then unchecked it. Changed the order of the modules to load. I put thinkpad_acpi first. I also modified laptop-mode to run even when on AC.
Decided to reboot.
Everything is fine. laptop-mode controls the brightness like a champ.
