This will help you set up vnc for the cs machines for UNM Obviously, if you’re not a computer science student at UNM, this will not be very interesting to you. However, since I have been asked this question on multiple occasions, I figured it would be good to get the process documented and easily accessible. Here goes: Log into your CS account.
