Comment 5 for bug 1175098

Just ran into this exact problem after upgrading from 12.04 to 12.10, kind of annoying as I use VNC everyday. But it turns out I didn't need to recompile x11vnc as the latest test version worked - from the man himself, of course! It can be found in http://www.karlrunge.com/x11vnc/bins/. The one I used was x11vnc-0.9.14_TEST_amd64-Linux for Ubuntu + Openbox.

Hope this helps someone in the same situation.
