'Fixing' the right click menu in gvim in Ubuntu

Question

I have installed gvim in Ubuntu 12.04 and it has no right click menu.
For example, if I select a block of text and right click in the region, the size
of the selection changes up to the cursor position. I've been trying to create
a .vimrc by copying the relevant(at least what I can understand) parts from
the Windowsone so I may have missed a couple of settings related to it(I think).
How do you make the menu appear?

description:

:help popup-menu

setting:

:set mousemodel=popup

worked for me
