I'm using Remote Desktop Manager to access another system which uses Ubuntu 14.04 with Xfce 4.10 desktop. I recently installed Gufw. When I click it from Application Menu\Systems, it does not open.
update: When I try to open it in terminal it just says "Hangup". update 2: I tried to open Gufw directly (without remote desktop). It was opened. So, the problem is that Gufw can't be opened through remote desktop and Xfce desktop.
