Screen Dimming Setting In BIOS?

Framework Laptop 13

Is there a setting that allows me to control the screen dimming in the BIOS? I can barely see the screen whenever my Framework 13 boots to the Fedora disk encryption password screen, and the buttons on the laptop to increase the screen brightness don’t work until I am actually booted into Fedora KInoite.

If this isn’t something that is possible now, is this a feature that could be implemented in future BIOS updates?

I have the same issue, couldn’t find a BIOS setting.

Check out this thread for Arch: [SOLVED] LUKS password screen during boot very dim / Newbie Corner / Arch Linux Forums

The following gives me OK brightness:

echo 50000 > /sys/class/backlight/amdgpu_bl1/brightness

Just need to figure out how to plug it into the start-up sequence.

There is a kernel bug with default brightness. It’s got a fix on the mailing list.

Thanks Mario! So I guess I’ll just wait for 6.16 to ship with Fedora.

It’s unfortunately going to miss 6.16 final due to timing of the patch. But it will come shortly after.

You can request fedora to bring it in sooner though if you want. They’re pragmatic.

Here is the patch. It’s trivial so unfortunate on the timing.
