Throughout the day I use VNC on a regular basis to access my computer from various places on campus. Well, my roommate noticed things moving around on my computer one day and when I told him what it was, he now thinks it is funny to mess with it from my room while I am using it somewhere else on campus. I thought he would get over it but now he does it all the time, and today he just erased a paper I spent 3 hours writing.
Is there anyway to keep my computer inaccessible when I am running a VNC server on it? Can I somehow disable the monitor or keyboard on that end?
