I just made a fresh install of Ubuntu 22.04 on an SSD on a fairly old computer (AMD Athlon II, IIRC) with an Nvidia GeForce 750 Ti graphics card. It installed without errors and ran just fine. I had an old HDD with X-plane (flight simulator) on, I ran it, and I could fly! The graphics was great, and everything worked just fine...
...until it didn't.
Suddenly, it just froze. Everything stopped. I couldn't move the mouse cursor, and I couldn't toggle the caps lock or num lock LEDs on the keyboard. In the end, I just cut the power.
Now, when it boots, there's absolutely no screen output - not even the Ubuntu logo that was there originally, when it booted. No HDMI signal - the screen doesn't even turn on.
Thankfully, I had the great idea of installing openssh-server, so I can SSH into it. And when I do, everything looks hunky-dory. There's internet connection, and I can see all the files. It just doesn't output any video. At all.
So I'm at a loss here - what do I do? Of course, I could try reinstalling it all over again, but didn't Einstein say that doing exactly the same thing all over again and expecting a different result is the legal definition of insanity?
I'm guessing that since I still have SSH access, I have some options. I just don't know what they are.
