To modify these properties

  • Execute the following commands:
xrandr --output HDMI-0 --set TegraOverlayPriority 0
xrandr --output HDMI-0 --set TegraOverlayBlendmode PremultSourceAlphaBlend
Note:

X does not have a notion of alpha blending, so all alpha blending on the enabled display must go through OpenGL ES rendering. Alpha blending for natively rendered pixels is undefined.
