It all started yesterday when I noticed some software updates for nvidia stuff. The software updater didn't give any errors, but a couple of hours later, when I tried opening CS:GO, I only had about 40 fps, which is far from the usual. As suspected, the nvidia card was disabled. Since then, I tried pretty much everything, so here's some images and command outputs:

Failed to enable/disable unit: Unit file nvidia-fallback.service does not exist. I don't know what else I can do besides reinstalling Ubuntu, so I'd appreciate any help. If you need more info, please let me know.
EDIT: Thank you for your help but eventually I grew tired of the drivers not working so I just installed Ubuntu 19.10. Funnily enough, last time I had some trouble getting the drivers to work but now they do out of the box.

Try
sudo apt purge nvidia*
(Do that while in a directory with no files matching nvidia*, you want apt to remove everything connected to nvidia)
And reinstall nvidia drivers via the Additional Hardware wizard.
The missing fallback service will stop prime-select from working.
