set of data retrieved from openQA test:
===
_graphical_wait_login-var_log.tar.gz
autoinst-log.txt
vars.json
video.ogv    <= video of install and reboot
serial0.txt
===
var	     <= directory from unpacked above tar.gz
journal3.log <= generated from var/log/journal/...

I do not know what log entries could explain why
do not have graphical login screen.
