Help with Fedora 42 and 5090 drivers

I installed Fedora 42 on my new Lenovo Legion pro 7 with 5090. Now I’ve a problems with Nvidia’s drivers loading.

I’ve tried a lot of things including rebuild modules with akmods and dracut, login with Wayland or X11, but nothing works. So, any help will be appreciated.

What are you showing Nvidia X Server Settings? sudo nvidia-settings

nvidia-setting doesn’t works properly

sudo nvidia-settings

Late reply, sorry. It seems like either your install of drivers is bad or that you might have secure boot on which is preventing the driver from signing.

5

I disabled secure boot and reinstall drivers but it still doesn’t works.
I wondering whether 5090 is still new and drivers not baked enough. WDYT? any workarounds?

I can confirm a similar experience. I attempted a fresh install of Fedora 42 on a secondary drive in my machine with a 5070 Ti and couldn’t get a stable, working desktop. Interestingly, I’m running Bazzite on that exact same system without any issues. Your theory about the drivers not being fully “baked” for the 5070 Ti in the standard Fedora repositories seems plausible, considering Bazzite’s focus on providing a more out-of-the-box gaming experience, which often includes more recent or patched drivers.
