I’m not sure if this is the best community to post in, but I just bought a used computer and slotted in an RX480 as the GPU. I installed KDE Neon 5.27 on it, and it worked flawlessly for 2 days.

Then, even though it was working earlier today, it slept and then would not wake up. So I turned off the power and turned it back on again, and was greeted with this error screen:

The only prior error message I’d gotten from the system was when I tried to install wine for one application, it told me some packages weren’t up to date, without a way to fix it. I can enter the BIOS just fine.

What is going on? How do I fix this?

    This was probably supposed to say “journalctl -xb”

      Okay, that command works for me. The last line says that /etc/hosts:7: hostname “SuperSpruce_Iron_3900X” is not valid, ignoring.

        Not sure if this is the root cause of your boot failure, but underscores in hostnames are not allowed. A- Z, 0-9 and - are the only allowed characters.
