When I upgraded to Ubuntu 18 and rebooted I had the "Failed to start session" error. Pressing ctrl + alt + f1 I found myself in a terminal, and used sudo apt-get install --reinstall ubuntu-desktop, then rebooted.



After entering my encryption pass Im encountered with the error:



 WARNING: Failed to connect to lvmetad. Falling back to device scanning.

This message is shown for 1-4 seconds, after that it just goes black and then it shows the same message again. Nothing happens by pressing anything. If I press alt+f3 (or similar) the login terminal can be seen briefly, before going completely black and continuing the loop.



There seems to be no end to the loop and I am a bit desperate to find a solution, I've found nothing similar to this :(
