amdccle the setting is enabled to disable the onboard laptop monitor and only
drive the external monitor, calling runlelvel1(i.e. terminal with login prompt)
via ctrl-alt-f1 leads to external monitor turning off("hdmi- no signal, going
to sleep"). ,pressing ctrl-alt-f7, and pressing enter a few times wakes up the
monitor again.
