I had logged into Ubuntu 18.04.4 desktop, then I pressed Alt-Ctrl-F3 to get a TTY and logged in there.

At some point I look up and see the last of the boot messages and Alt-Ctrl-F2 does not get me back to the GUI login.

I can't get anything to change but my programs are still running on my desktop.

What mysterious key did I press and what do I hit to get back?

At this point I would have to power off, and I don't want to lose my work.

Thanks!

  • Are you sure the GUI is at F2? Did you try other F keys? Does your caps lock LED toggle on and off when you press it? Mar 25, 2020 at 3:08
  • no caps light on my keyboard but it is a Logitech three receiver model and it works on the other two PC ... tried F2 thr F6 with Alt Ctrl ... Mar 25, 2020 at 4:48
  • ... actually ... CAPs lock does work on the other two PC when I switch ... but never lights on this box. Mar 25, 2020 at 4:50
  • I plugged in a wired keyboard and the caps light does not light when I hit caps lock key ... does work when I plug in another PC. Mar 25, 2020 at 5:07

    If the caps lock light LED doesn't toggle, that's usually a "bad thing". Others may have ideas, but generally if I see that behavior, I end up rebooting. Mar 25, 2020 at 13:58

Finally figured this out.

I had an IOmega 2 port KVM between my two PC's.

Once I added 4 opto isolated USB devices ... problem went away.

I took to wearing a grounded wrist strap just to avoid static electric effects as well.
