I'm accessing my Pi via SSH.
My network is too slow to actually forward the Pi's desktop back to my laptop, so I have a monitor connected to my Pi. When I
startx through Putty, I see the desktop on my Pi. All is good.
However, I cannot do anything with this desktop, as all I have is the mouse and keyboard of my laptop.
How can I forward the mouse and keyboard input from my laptop to the desktop on my Pi?
