First of all, likely it should be "#", not "$" (run it as root: either 
sudo or su). Next

    journalctl --priority=err

or

    journalctl --priority=warning

instead of grep.

However in the case of obscure issues I would recommend against any 
filtering besides time. After system freeze and reboot skim through all 
last messages from previous boot. There is a chance that the action 
caused hang left some traces

    journalctl -b -1

Time window of the following command may be too narrow, but in some 
cases it is more convenient

    journalctl -b -1 -e

You can adjust boot ID to get access to earlier failures.

/var/log/Xorg.0.log.old

but avoid graphical login before you copy it. Likely /var/log/Xorg.0.log 
is created by current LightDM session.
