Well ... putting my sata controller in AHCI mode (in the BIOS) seems to have solved my problem.

Has anyone actually tried to see if it's true? I don't have access to excel and copilot so I can't check.

People had to submit light, dark , horizontal and vertical versions.

Not one knob but you can adjust multiple sources with hardware knobs.

Or maybe I don't understand what you'd like?

Thanks!

Glad I could help. I've also seen some DIY projects, but not sure how hard that would be.

I saw somewhere that Fedora has stopped supporting legacy bios so I tought that might do the trick, but nope ... same problem with Fedora 36.

I finally solved the problem by putting the SATA controller in AHCI mode (in the bios).

Yep . I hadn't tried the install from the live USB since at first I created a fedora-server USB installer , so I gave it a go. It boots in the live-os just fine, but installation on HD fails.
