I received my 7840 mainboard yesterday and excitedly swapped it into my laptop then spent all day trying to get pop os working properly. it wouldnt. i tried to get ubuntu working with frameworks instructions but it was never quite right. it seemed like my only option was to switch to Fedora which im not a huge fan of. i was having display issues no matter what, and using nomodeset would get it to work, but with incorrect display settings.
Then this morning i noticed there was a BIOS update to 0.0.3.3 so i installed it. Immediately all my issues with pop os went away and things are working perfectly.
Hope this helps someone.
when i installed fedora 39 the fingerprint sensor worked out of the box. but touchpad gestures weren’t working and most of my gnome extensions werent compatible. Plus i personally dont like rpm distros.
