Solved my nvidia eGPU/Razor X crashing on Lenovo Yoga 7i Carbon in Fedora Silverblue/Kinoite:

1. normal driver instructions for Silverblue https://medium.com/@egee_irl/install-nvidia-drivers-on-silverblue-edd499244aa2
2. connect egpu and call `lspci | grep VGA` and write down the id for your gpu (mine is 2e:00.0)
3. setup egpu setup: https://github.com/claudio-walser/egpu-setup and fill the BusID in /etc/X11/xorg.conf.egpu, mine maps to: "PCI:46:0:0" (0x2e=46)
3. before you call `egpu start`, modify `/etc/X11/xorg.conf.egpu` to https://hastebin.skyra.pw/urucagutun.pgsql
4. start it!
