62 * 1. Launch Xvfb on available DISPLAY.
63 * 2. Make an xcb connection to this display.
64 * 3. Launch xkbcomp to change the keymap of the new display (doing
65 * this programmatically is major work [which we may yet do some
66 * day for xkbcommon-x11] so we use xkbcomp for now).
67 * 4. Download the keymap back from the display using xkbcommon-x11.
68 * 5. Compare received keymap to the uploaded keymap.
69 * 6. Kill the server & clean up.
