17 Purpose:
18
19 Delete the "InvalidDisplay" key which causes the display
20 applet to be started on every boot. For some reason this key
21 isn't removed after setting the proper resolution and even not when
22 doing a driver reinstall. Removing it doesn't seem to do any harm.
23 The key is inserted by windows on first reboot after installing
24 the VBox video driver using the VirtualBox utility.
25 It's not inserted when using the Display applet for installation.
26 There seems to be a subtle problem with the VirtualBox util.
