Authentication Failure Switch to greeter












33















I'm experiencing a very annoying problem on Ubuntu 18.04.



Whenever my laptop resumes after being suspended I'm completely unable to login and get the error;



Authentication Failure Switch to greeter


The issue is well described here, although it seems no one has found a solution to it.



https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1733557



Is there any way to stop this from happening?



Update:



To anyone who comes across this, the shortcut to get to the greeter without having to reboot is Ctrl-Alt-F1.



Also if anyone of the people who voted to close this question had actually read the bug report above they'd see that users still report the same issue after upgrading to 18.04.

  • Thanks. This at least saves me having to do a reboot every time which is awesome!

    I would like to reopen and post that you can use $ sudo apt install --reinstall lightdm $ sudo service lightdm restart

$ sudo apt install --reinstall lightdm
