     301== Hardware Accelerated Desktop UI
     302While it is not typical to use an embedded system as an Ubuntu desktop we often are asked how to do it.
     303
     304With the Ubuntu Focal (20.04) all the software is in place to give you 2D and 3D hardware acceleration with the IMX6 with a modern kernel such as the Linux 5.4 kernel we use in our pre-built images.
     305
     306Here are the steps to add a desktop UI:
     307 1. Install gnome desktop:
     308{{{#!bash
     309# add packages
     310apt install gnome-session gnome-terminal
     311# add a non-root user (required to login)
     312adduser gateworks
     313# sync the filesystem and reboot
     314sync
     315reboot
     316}}}
     317  - you'll notice dragging opaque windows around is fairly smooth as it is using hardware 2D acceleration
     318 1. 3D opengl hardware acceleration:
     319{{{#!bash
     320apt install mesa-utils glmark2
     321# from gnome-terminal running on display from above:
     322glxgears # 75fps on IMX6Q displaying HDMI 1080p60hz
     323glmark2 # another test that renders via opengl
     324}}}
     325 1. GStreamer Video display
     326{{{#!bash
     327apt-get install gstreamer1.0-x gstreamer1.0-tools libgstreamer1.0-0 \
     328  gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \
     329  gstreamer1.0-libav gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio \
     330  v4l-utils alsa-utils
     331# using kmssink will render right over GUI
     332gst-launch-1.0 videotestsrc ! kmssink
     333# using fbdevsink will also render right over GUI
     334gst-launch-1.0 videotestsrc ! fbdevsink
     335# using waylandsink will render 'within' GUI
     336gst-launch-1.0 videotestsrc ! waylandsink # renders 'within' gui
     337}}}
