I was running Fedora. Something like 27 or so. I needed drivers. I don’t remember if it was AMD or Nvidia, but they were only available on RedHat.
So I downloaded the RedHat drivers for the GPU and forced it to install. It worked! It was great.
Then when I updated the distro to the next release… everything failed. It was dropping into grub, but no video was output. Ooof.
So I ended up enabling a terminal console and connecting to it via a serial port to debug. I had to completely uninstall that RPM and I was never happy that it was properly gone. So a few months later I ended up reinstalling the whole OS.
On the plus side, I learned a lot about grub and serial consoles. Worth it.
