I would say that it is better to fix discrepancy between (likely) 
/etc/hostname and /etc/hosts and to use a consistent name. If "thinkpad" 
is the preferred one then update /etc/hosts otherwise check

      hostnamectl

and update (as root)

      hostnamectl hostname caterina-thinkpad

There was a thread that "home" as the top level domain might not be 
really safe (somebody might register it). A reserved domain is 
"home.arpa" so e.g. to have "thinkpad", the /etc/hosts entry should be

127.0.1.1       thinkpad.home.arpa thinkpad

I have not tried it, but I expect that startx should have no issues with 
output redirection, so to capture its messages to a file

      startx |& tee /tmp/startx-messages.txt

Another places to look for errors are ~/.xsession-errors and

     journalctl -b --user
