display-dga : Display using XFree86-DGA extension
display-dga: [-noinput] [-nocursor] [-physz==>sizex>,<sizey>[dpi]] [<display>]
Uses the XFree86 DGA extension to do fullscreen direct framebuffer access on X servers which support this. For systems without kernel framebuffer support, the program must be run as root for this target to be able to mmap /dev/mem.
This option will override the physical screen size reported by the X server, which affects applications which wish to remain resolution independent. :p:`sizex`, :p:`sizey` are the x,y size of the screen in millimeters, unless the optional dpi string is affixed, in which case, they represent resolution in dots-per-inch. Yes, there are two equals signs there, for reasons of compatibility with other targets.
The X display to connect to, otherwise defaults to the display specified in DISPLAY.
