Login Disappears, Can't Reach TTY

Using a desktop computer. It's been working fine, but then I updated Ubuntu, and after restart I'm seeing problems. After booting, I see a login screen, which sometimes has a login window and sometimes doesn't. Regardless, no keystrokes are showing up in the GUI. The mouse cursor moves, but I can't click anything. I have tried CTRL+ALT+F1 and all the other function keys F2 - F12, with and without FN, but no command line interface appears.

I can get into the BIOS by pressing esc during boot, and the most promising looking option is "Launch EFI Shell from filesystem device" but it tells me "WARNING Not Found."

Any ideas?

The BIOS is American Megatrends, Inc. I can boot from it but just puts me back into a dead end since I can't bring up a command line interface.

Possibly irrelevant update: there is a very short window of opportunity in which I can press CTRL+ALT+F3 and bring up a non-GUI screen, but it endlessly scrolls text very quickly. I could only read it by taking a video and slowing it down. I'm seeing lots of hard to understand stuff but this doesn't sound good

"Comm: (python3) Tainted: P" and "Watchdog: BUG: soft lockup - CPU#21 stuck for 22s!"

Sounds like you need to remove that custom DE and troubleshoot from there.

Sorry, I'm new to this. Are you saying I should remove hardware from the machine, or something else?

No you said someone made a custom desktop environment (DE) and you are using that. I said remove that first it may be the issue. Go back to a supported DE.

If the login is showing on tty1 it is NOT a video card driver problem :) I agree with David: it is likely connected to the custom DE.

I see, just bad terminology on my part. By "custom desktop" I mean a desktop computer that was custom built. I will edit.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
