Hi! I have been using this laptop with manjaro for many years now. Since I don’t game much, I don’t use the dedicated GPU much, so unfortunately I don’t know which update broke my setup. At some point bumblebee (I don’t remember what version) used to work.
However, now I get errors very similar to: _forum.manjaro.org/t/solved-primus-fatal-bumblebee-daemon-reported-error-xorg-ee-no-devices-detected/32436 . However, I cannot follow the solution proposed there, since mhwd does not seem to offer prime drivers for my card. According to the NVIDIA page for searching drivers, the latest version for my card is 418, which might not work with prime at all. I am currently using kernel 5.14, but I am willing to use an older LTS kernel, if it helps.
The goal of my post is to get ANY method of hybrid graphics working (bumblebee, prime, optimus-manager, …).
