Code review comment for ~williamhsu/plainbox-provider-checkbox/+git/plainbox-provide-checkbox:bug/lp-1884235/exchanged-the-sequence-of-graphics-log-parsing

I leave some suggestions in below lines.

BTW, currently the Ubuntu supports x11 and wayland. If this python script is a generic test case for "graphics_driver" then better to confirm the current session whether executing under x11 before starting the verification (might leave wayland as unsupported test environment).
