I frequently use VNC to remote desktop to home home computer, which has a dual monitor setup. The problem is that I only see the primary display when I VNC to my home computer. Anything on the right monitor is an absolute bitch to get to, and I'd rather just have a slider bar that lets me slide over to my secondary display. My friend has this setup enabled (although he doesn't know how he got it to work) and I've tried all I can think of, and searches turned up to be not to helpful for me. Anybody here have any suggestions on what I could possible do with this setup?

If VNC is capable of it, I would guess it's in a setting inside VNC?

I've checked for it, but it was nothing obvious.
