* Test KMS/DRI output subsystem
* This is an example how to use the output subsystem. Invoked without
* arguments it prints a list of all connected outputs and their modes.
* If you pass any argument it will enable all outputs for 5seconds.
*
* This lists all outputs:
* $ ./test_output
*
* This would show a test screen:
* $ ./test_output something
* The test screen is a colored quad with 4 different colors in each corner.
