sudo gedit problem

xarzu

I just set up a Ubuntu VM1 and I explanded the desktop to cover two monitors. This might be the problem I am having with the editor. When I type 'sudo gedit" I get this error and no editor comes up.

After I gave my password, it has this strage error "Authorization requried, but no authorization protocol specified"

I do not now what this means and in a previous virtual machine with Ubuntu, this never happened before.
