Description Jan Ziak (http://atom-symbol.net) 2017-02-04 15:51:39 UTC

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.

Fixed (on R9 390 at least).
