<pre>Pressing Alt+Ctrl+F1 switches from X11 desktop to Linux console.
Pressing Alt+Ctrl+F7 switches from Linux console back to X11/Xorg desktop.
With driver "amdgpu" in /etc/X11/xorg.conf
(x11-drivers/xf86-video-amdgpu-1.2.0), my BenQ HDMI display is buzzing (making
noise) for about 1 second after pressing Alt+Ctrl+F1. Switching back to Xorg
desktop by pressing Alt+Ctrl+F7 executes immediately without any unnecessary
buzzing.</pre>
