QA:X basic input handling test case

Description

A very simple test to ensure that the X server is able to receive and process input.

How to test

1. Plug in a USB mouse and keyboard
2. Start X
3. Confirm that moving the mouse causes the mouse pointer to move
4. Confirm that clicking the mouse buttons will send click events
5. Confirm that pressing keys on the keyboard causes keypress events to be sent

All about choice
The tester can use whatever means are convenient to confirm that the keyboard/mouse are functioning. The programs xev and xinput test might be helpful here, but really just wiggling the mouse and logging in through GDM/KDM/etc. is sufficient proof.

Expected Results

1. The pointer moves in the same direction as the mouse is moved
2. Mouse button clicks are recognized and handled
3. The user is able to type letters using the keyboard
