Consider Universal-Blue:

May I also suggest installing Silverblue or Kinoite and rebase to:

• https://universal-blue.org/images/nvidia/

Or try the ISO:

• https://github.com/ublue-os/main/releases

It's cloud based image of Fedora with NVIDIA drivers slipped right in there, easy peasy.

Had the same problem after upgrading from 37 to 38. Its an nvidia problem

1 - Boot an older kernel OR Drop to a TTY (Ctrl + Alt + F3) OR Boot into runlevel 3 (on grub, press 'e' when the list of kernels show, look for the line with quite splash nvidia-drm.modeset=1 and add the number 3 there, then Ctrl + X to boot) 2 - Login on your terminal and dkms status. If you see something like /var/dkms/nvidia/525.116.03/source/dkms.conf does not exist, remove the entire directory of the failed version rm -rf /var/dkms/nvidia/525.116.03 3 - sudo dkms autoinstall 4 - reboot if no errors and profit, otherwise rinse and repeat step 2-3

PS: If dkms tells you nothing at all (after the upgrade): remove the drivers /etc/nobara/scripts/cosmo-nvidia-wizard/remove.sh

reinstall them /etc/nobara/scripts/cosmo-nvidia-wizard/install.sh

If your dkms status is ok, you probably have a mismatch in your initramfs and root. just sudo dracut -f --regenerate-all and reboot

Thats what i have done now it works fine.

If you have an nvidia card you need to select the fallback (or something) entry in grub

If I recall correctly I had to wait a good 90 seconds for anything to pop up after grub when I've installed nobara.

Have you tried waiting a good minute or two?

I'm kinda meh on nobara, the install is cool, performance is great but I've had some weird problems I never had on xubuntu. 🤷‍♂️

What is the size of the usb stick you're flashing it onto? Maybe try it again with a bigger usb stick?

Im not sure exactly but maybe its secure boot in your bios?, back in the day had to disable that for ubuntu
