I just upgraded to Ubuntu 19.10. Upgrade was done via update manager GUI. I am using nvidia as a graphics driver.

After upgrade I get logged in but I get this screen:

How do I troubleshoot this?

I ran sudo dpkg --reconfigure -a. This resolved the first problem, but now I am at the login screen and unable to login.

I have looked at this question here:my .xauthority and .iceauthority permissions are correct although .xauthority is 0KB. /tmp permissions are also correct. I don't have lightdm installed.

I have also checked the Xorg.log and .xsession log. Renamed the extensions folder as well as the .xauthority file. no luck.

  • Are you using wayland or xorg? – Wayne Vosberg Oct 17 at 15:47
  • I don't know. I am on the default. – user1373927 Oct 17 at 15:48
  • On the login screen where you enter your password, click on the gear and try the different options -- should be gnome, gnome on xorg, ubuntu, ubunton on wayland. Maybe others. There are some known issues with nvidia but I'm not sure if this is one or not: wiki.ubuntu.com/EoanErmine/ReleaseNotes – Wayne Vosberg Oct 17 at 16:02
  • I don't have a gear icon. – user1373927 Oct 17 at 16:05
  • Should be right next to the Sign On button. If not, you may have only one environment installed. If you can get to a console login try sudo apt-get install xorg xwayland gnome – Wayne Vosberg Oct 17 at 16:07

I had automatic login enabled. I just updated this file: /etc/gdm/custom.conf

and commented out these lines:


After this I am able to login. Is this a bug?

  • worked for me - thank you! – Randomize Oct 17 at 18:08
  • Worked for me with path /etc/gdm3/custom.conf (see the 3?) – pommedeterresautee Oct 25 at 10:31
