In linux (ubuntu 9.10, in my case), is there any command similar to gksu but without root privileges? I've followed the instructions on pida's site and installed pida 0.6. When I run it using ./pida-run.py from terminal it starts fine. But when I made a gnome menu item and indicated the above command (with the correct location) to run it, it wouldn't run. So I was thinking if I add gksu alternative, maybe it'll work.
