I was wondering if it was possible to have a Fedora 41 setup like so.
Secure boot
UKI (unified kernel image) with systemd-boot
nvidia drivers for 30xx series on a laptop
Does the KDE installer image support this? If not, should I use the everything-install image?
I tried this setup with Fedora 40 last time, and nvidia drivers wouldn’t install because of grubby vs sdubby(?, if I recall correctly) package clash dependency.
Should I skip this and just go with the classic install?
I know this is an older question, but I can answer this one so I will.
Is it possible? Yes.
My system does this (well almost this) boots UKI’s with secure boot enabled and uses the proprietary nvidia drivers. I boot directly from the UEFI, not via systemd-boot, but it is close enough that I can for sure say it can be done.
Is it sometrhing that you can do with a manual installer? No.
It is worth noting that I set up UKI booting on my system completely from scratch, and while I know my setup could do this I dont know if the more “official” fedora UKI setup can. IMO setting this up from scratch during a system install is much easier if you do a full manual install…i.e., load up a fedora live usb and then from that live usb manually create your partitions/filesystems, mount them, install fedora with dnf --installroot=..., then enter the system with systemd-nspawn and do your manual initial setup.
If you are still interested, the main thing you need to do is generate “personal” self signed x509 secure boot keys, register them with secure boot, and then sign the nvidia kmods that get built by akmods when the nvidia driver installs/updates using your personal secure boot signing key.
