The HP Integrated Remote Console Virtual Mouse, which is standard equipment on all Proliant and Integrity servers, produces absolute coordinates instead of relative coordinates. This is done to synchronize the position of the mouse cursor on the client desktop with the mouse cursor position on the server. Mousedev is not designed to pass those absolute events directly to X, but it can translate them into relative movements. It currently does this for tablet like devices and touchpads. This patch tells mousedev to also enable this function for the HP virtual mouse. This patch is narrower in scope than my previous patch of the same name, which enabled abs-to-rel translation for all devices with ABS_X, ABS_Y, and BTN_LEFT.
This patch enables the mouse pointer to move when using the remote console. Without this patch, the cursor will not move.
