The GUI lets me select one of my (two) users at start-up, then skips to the screen where I should enter the corresponding password. However as soon as that screen pops up it shows the message "authentication failed" (even before I can enter a password) and after 1 or 2 seconds the systems skips to what looks like terminal mode on the screen showing the processes it started up, the last one being "[OK] Started PackageKit Daemon" and remains stuck there.

I can login via terminal mode instead of via GUI. I added an extra user via terminal mode. That all seems to work fine, but that doesn't solve the GUI problem. Who can help me out?

I am a bit of a layman in Ubuntu, so please correct me if I don't provide the information you asked for. Prior to selecting a user at login the content of the log file seems okay. After that (and extending the 20 you mentioned to 60) it shows /usr/lib/gdm3/gdm-x-session[5392]: (WW) xf86OpenConsole: VT_ACTIVATE failed: Operation not permitted followed by "Fatal server error" and "xf86OpenConsole: Switching VT failed" followed by more terrifying news where gdm3 seems to be the common denominator.
