Can't login after update

[JackGray]

mmcglynn, I saw the same misbehavior today after installing the update.

Thanks to your comment re:  "Ubuntu login loop", I was able to find an answer.

The relevant articles I found:
http://ubuntuhandbook.org/index.php/2020...ia-driver/

and

https://askubuntu.com/questions/1231410/...untu-20-04.

In my case, my hard drive was full; a user comment in the 2nd article above re: using "sudo apt autoremove" did the trick for me.

I hope this helps you!
