Base of this image builds a tagged version of ubuntu with installed display server X.org enabling the device's DVI port plus the desktop environment Xfce turning the device in a desktop computer with mouse and keyboard support.
The display server needs access to the following gateway's host devices:
- console tty0
- console tty2
- frame buffer fb0
- input devices inputs
- Direct Rendering Manager dri
- VGA arbiter vga_arbiter
Starting the X11 server needs full access to the /dev devices mentioned above, else the error "Fatal server error: AddScreen/ScreenInit failed for driver 0" is reported durind start. Only the privileged mode lifts the enforced device cgroups limitations.
