In PR2, the Genio 720/520 EVK enables the eDP adaptor by default, even if the eDP panel is not physically connected.

This may lead to some GUI test programs, such as gst-launch-1.0 with waylandsink, to appear not showing on the DSI display.

To remedy this, you can modify the Weston configuration to disable the eDP panel in Weston compositor.

  1. Boot and login to console
  2. Edit /etc/xdg/weston/weston.ini
  3. Add the following section to the ini file:
[output]
name=eDP-1
mode=off

Note that the name field should match the connect name you queried from DRM, e.g.

# modeprint mediatek | grep Connector
Connector: eDP-1
Connector: DSI-1
  1. Re-start weston with
systemctl restart weston

After restarting Weston, the eDP panel should be excluded from Weston, and subsequent GStreamer waylandsink should be output to the DSI panel instead.
