Try pressing ctrl-alt-f8 to switch to a text console. If the text login
appears, then the issue was most likely in the graphics stack. If still
blank, try pressing ctrl-alt-del. On a text console this should result
in a reboot. If it reboots, you should be able to see logs with
'journalctl -b-1'. If it doesn't respond to ctrl-alt-del, then it's a
kernel driver issue. Further debugging is possible, but let's check the
easy things first.

One of the reasons to introduce power-profiles-daemon was the dbus API
that gnome knows how to use. TLP and others do not provide the same
API. power-profiles-daemon.service conflicts with tlp.service, probably
because they'd both try to set the same settings. So if you want
p-p-d.service, then make sure it is enabled and disable tlp.service.

Great to hear that. I'd say that this cycle seems pretty smooth so far.
