I'm having the same issue found here (and tried to suggested solution, but that didn't help any):


But it won't let me comment on that one, says I don't have enough reputation. I used to be able to use the GUI all the time, but then after applying some patches a few months ago, it stopped letting me log-in to the GUI. I hoped it was a temporary bug that would eventually get fixed, but it's still a problem, and preventing me form using the desktop GUI (and thus some programs).

The CLI works fine, but in the GUI, I select my user name, put in the password, it acts like it's logging in, then the screen goes black, and eventually it goes back to the log-in screen.

I'm running "Ubuntu 16.04.1 LTS" and have tried applying the latest patches with "apt upgrade", but the problem persists.

The only error message I see when logging in on the CLI:

[ ##.######] systemd-login[1742]: Failed to start user service, ignoring: Unknown unit: user@1000.service

I put #'s in there because that number seems to change every time.

Thanks in advance for any suggestions or help.

If I login to the CLI, then run "startx", it does basically the same thing, dumping me back to the CLI.

Here's the only error message I see in the output:

xinit: connection to X server lost

  • Yeah, my system boots fine, so I don't think I need a reinstall. I gives me a log-in both CLI and GUI. The difference is that I cannot log-in via the GUI, it goes black, then jumps back to the log-in screen. – Spaldam Jan 3 '17 at 5:58
  • Your desktop is broken and you need to re-install from CLI. sudo apt-get install --reinstall ubuntu-desktop or modify to suit your desktop version. – George Udosen Jan 3 '17 at 6:05
  • Thanks for the suggestion. I tried the reinstall just now, and the behavior has not changed. Even rebooted, no difference. – Spaldam Jan 3 '17 at 6:19
  • What would be involved in the other suggestion to "modify to suit your desktop version"? – Spaldam Jan 3 '17 at 6:25
