The first tip I’d recommend is to go into your power management preferences, make sure your settings for “on AC” and “on battery” are set to not dim display when idle. This is usually a checkbox found for both AC and battery tabs. Also, do the same with the option for “Reduce backlight brightness” in the battery section. To make sure the changes take immediate effect, be sure to restart your computer.

Today Joe H. writes,
Hi there, really enjoy your site. I love using Linux and have tried various distros but still consider myself a newbie. My problem is that when I log on, no matter what OS, I have a dull screen on my laptop and have to adjust the brightness button. Ok no big deal with the likes of Mint, Ubuntu, etc, but with the lesser used distros I can’t find the brightness button, and so stops me using these distros. I am guessing this is the fault of the laptop (Acer). Is there a permanent fix? Can it be done in the bios or in a terminal? Would love to solve this problem but so far cannot find the correct answer, (having tried various wrong ideas). Thanks for any reply, Joe. (Liverpool, England).

Hi Joe! This is a frustration point, as each laptop seems to take a different approach to setting the brightness. Because it sounds like you’re wanting to keep the screen bright as it can go for better visibility. The first approach I will show you is an older technique but will provide you with full brightness upon every reboot.
Full Linux backlight brightness even when idle
