Hmm I don't appear to have an up to date Xorg log, unless I'm misunderstanding
where it should be:

head /var/log/Xorg.0.log

I have no dmesg other than the one I provided, there were no other errors in
dmesg. 


So journal is probably the best bet. I can attach it all if you like:
sudo journalctl -b -1 -p 3
