If you're seeing high CPU utilization in Xorg.bin, it's probably an 
indication that you are using gnome-shell, and your graphics driver 
doesn't support GL acceleration.  In that case, Xorg.bin will use 
software rendering (llvmpipe).  So, check your logs for further info.

$ systemctl list-units -t scope

$ journalctl -b -u session-5.scope

You could create a shortcut for this in bash, like this:

alias xsession-errors='journalctl -b -u $(systemctl -t scope | awk 
"/user $USER\$/ { print \$1; }")'
