Solved this on my testing Ubuntu 20.04 LTS VM by installing greeter from MATE:
``` sudo apt-get purge arctica-greeter arctica-greeter-guest-session sudo apt-get purge kylin-greeter ukui-greeter sudo apt-get autoremove --purge sudo apt-get install --reinstall ubuntu-mate-lightdm-theme ``` (see https://askubuntu.com/a/1233695/66509 ) ** Tags added: bionic eoan focal xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1068605 Title: List of session type does not fit on screen with many window managers installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-greeter/+bug/1068605/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
