I run ubuntu 10.04 and I'm trying to disable suspend and hibernate mode so I typed this: Code:

sudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy

but I get this error: Code:

Gtk-WARNING **: cannot open display:

Anyone know what the problem is?

... does gksudo gedit... make a difference? –  fossfreedom Feb 12 '12 at 23:12

1 Answer 1

for graphical applications, such as gedit, you should use gksu

gksu gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy

alternately, you can try nano

sudo nano /usr/share/polkit-1/actions/org.freedesktop.upower.policy
