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.

Add:

Defaults env_keep+="DISPLAY"

to the /etc/sudoers (via visudo)

will work.

Also , you can try to use:
gksudo gedit

sudo nano probe

will relieve your grieve. Ever.
