Title:
  Raspberry Pi HDMI output has thick black borders

Status in linux-firmware-raspi2 package in Ubuntu:
  Fix Released

Bug description:
  Raspberry Pi HDMI output has thick black borders.

  This appears to be due to some DRM property defaults coming from the
  kernel. You can fix them in Xorg sessions with:

    xrandr --output HDMI-1 --set "top margin" 0
    xrandr --output HDMI-1 --set "bottom margin" 0
    xrandr --output HDMI-1 --set "left margin" 0
    xrandr --output HDMI-1 --set "right margin" 0

  To work around the issue in Wayland sessions you will need to log into
  Xorg first, run the above commands, then log out and into Wayland.
