We're going to need to analyse the hung gnome-shell process. Please
try to do this:
1. Install openssh-server:
sudo apt install openssh-server
2. Using a second machine, log into the offending machine via SSH:
ssh <USERNAME>@<HOSTNAME>
where <USERNAME> is your username, and <HOSTNAME> is either hostname or the
machine's IP address.
3. Reproduce the freeze.
4. From your ssh login, run:
killall -TRAP -u $USER gnome-shell
5. Look in /var/crash for a newly created file, something like
'_usr_bin_gnome-shell.1000.crash'
6. Upload the crash file using this command or similar:
ubuntu-bug /var/crash/_usr_bin_gnome-shell.1000.crash
7. Tell use the new bug ID that was created.
** Changed in: gnome-shell (Ubuntu)
