If no X running, no "power management", we get console with blinking cursor displayed, and we record it!

[yarikoptic]

Not yet sure if we need to address it directly, or our "sync" script would be smart enough to turn off display when not in use, but now that we have .service file starting videograbber so we do get recording going after I disable/stop gdm3:

root@reproiner:/data/reprostim# sudo systemctl disable gdm3.service
Synchronizing state of gdm3.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install disable gdm3
Removed "/etc/systemd/system/display-manager.service".
root@reproiner:/data/reprostim# ps uauxw | grep video
