Hi and welcome to :fedora:

Can you please try putting the power mode to performance to see if that resolves the issue.

There are several other posts regarding this issue already, linking one of them: F41 - Kernel 6.12.5 weird issue - #49 by david1r2r1

It does resolve the issue. I did search for similar issues but was unable to find one for resume from suspend. I guess I didn’t search hard enough. Thanks for the help!

I’ve got the same issue on a 2021 Zephyrus G14 GA401QM with RTX3060. Changing power profiles works for a moment then does the exact same thing whether Performance or Balanced. Only plugging in the power remedies the issue.

Facing the same issue on a Lenovo Ideapad 5 pro 2022. This is resolved by turning to performance mode.

If I set it to Performance, the brightness returns temporarily. Then, it flashes and goes back to having a 0% backlight.

Just boot with the previous kernel until you get 6.12.7. I think you have probably got it to update.

It has done this with every release of 6.12 and 6.11.
