28 * Test KMS/DRI output subsystem
29 * This is an example how to use the output subsystem. Invoked without
30 * arguments it prints a list of all connected outputs and their modes.
31 * If you pass numbers as arguments, it will enable these outputs and show an
32 * image on the given monitors for 5 seconds.
33 * The application terminates automatically after 5 seconds, however, you need
34 * to switch VT to re-enable output on your screen. This application does not
35 * reset the screen automatically, yet.
37 * This lists all outputs:
40 * This would show a test screen on output 0 and 4:
42 * The test screen is a colored quad with 4 different colors in each corner.
