This happens to me often whenever nvidia (dkms) rebuilds and the module compilation fails (for whatever reason).
Usually I drop into tty ctrl+alt+f2 as root, run dkms autoinstall (or just yay -S <your nvidia package>
should trigger dkms rebuild if needed) and then rebuild initramfs ( mkinitcpio -P
), reboot.
There is a youtuber for that!
Asianometry has a lot of "documentary"-style videos about microchips, civil engineering and histories of interesting industries (Zweis lenses, ASML, so on).
