What would be the equivalent in the systemd/journalctl world? Apparently Fedora 25 doesn't generate Xorg.log files anymore, the last modification timestamp on that one file is october 10th 2016...
See this page for how to access the xorg log output on various versions of fedora: https://fedoraproject.org/wiki/How_to_debug_Xorg_problems
