Synchronizing a Cursor from a Managed System with a Cursor from a Remote System

摘要

A method includes receiving reports of the pointing device events occurring on a remote computer at a host computer and performing computations in the host computer based upon the mouse reports. The method includes generating screen images in the host computer based upon the computations, the screen images not containing images of a cursor representing locations pointed to by a pointing device of the host computer. The generated screen images are transmitted to the remote computer. In some embodiments, the reports may be received by a remote console controller. An information handling system includes boot firmware to set a mouse to operate in absolute mode under control of the boot firmware. An information handling system separately transmits to a remote console controller of the information handling system screen images without a cursor and cursor images.

主权项

1. A method comprising:
receiving at a host computer first reports from a remote computer of pointing device events occurring on the remote computer; performing computations in the host computer based upon the first reports, the computations including determining locations pointed to by a pointing device of the host computer based upon the first reports, wherein the pointing device is active on the host computer and an operating system of the host computer determines the locations; setting the pointing device in absolute mode, wherein the operating system of the host computer sets the active pointing device of the host computer in absolute mode; generating screen images in the host computer based upon the computations and based on the active pointing device of the host computer being in absolute mode, wherein the screen images do not contain images of a cursor representing locations pointed to by the pointing device and the operating system generates the screen images in the host computer based upon the computations; transmitting the screen images generated in the host computer to a remote console controller of the host computer; and transmitting the screen images from the remote console controller of the host computer to the remote computer for display.
