Public bug reported:
When I login to my laptop running Ubuntu 20.04, after entering my
username, when I choose the "gear" button and select Ubuntu on Wayland
as the session type, my laptop freezes hard. Mouse and keyboard do not
respond, and the first three times I hit this issue I had to forcibly
power off. The normal (X11) Ubuntu session works fine.
However, I realized that I could still ping and ssh in, and doing that
gave me some clues to the issue.
I have keychain installed for password-less SSH, and my bash_profile has:
---
#!/bin/bash
# Get the aliases and functions
if [ -f $HOME/.bashrc ] ; then
source $HOME/.bashrc
fi
# Setup password-less SSH
[ -z "$HOSTNAME" ] && HOSTNAME=`uname -n`
keychain $HOME/.ssh/id_rsa
source $HOME/.keychain/${HOSTNAME}-sh
---
When I login via SSH from another machine after hitting the issue, I get:
[johnjaco@johnjaco-m-v02f: ~/Downloads] ssh john@192.168.1.10

This makes me think that gdm-wayland-session is somehow stuck on trying
to add the SSH key.
This issue is consistently reproducible, so let me know what additional
information is needed and I shall provide it.
