dga - test program for the XFree86-DGA extension
Dga is a simple test client for the XFree86-DGA extension. It fills the screen
  with a different colour for each key pressed. It prints some basic framebuffer
  parameters, and also keyboard and pointer events to stdout. To exit, hit the
  `q' key. Hitting the `b' key runs a simple benchmark, measuring raw
  framebuffer write and read speed (this takes one second each).
