Hello,

Code:

prakash@sputnik:~$ su -
Password:
root@sputnik:~# gedit

(gedit:13377): Gtk-WARNING **: cannot open display:

what should i do to able to open guis from terminal.
Thanks

As a regular user, try sudo gedit, which should give you temporary root priveledges and allow gui to work. The issue is that root doesn't have permission to use the gui...

Check out the Unofficial Ubuntu Guide

Thanks for reply.is it something to do with xhost+ command.

I don't know enough to say. But I remember one time before I was using sudo, I had to do something like export DISPLAY 0:0 or something like that as root...

Here's a thread that says your xhost+ works...

Code:

prakash@sarge:~$ echo $DISPLAY

Xlib: connection to ":0.0" refused by server

Try as user:

xhost +local:

Then maybe tell the program which display to use, which is something like:

someprog --display :0.0

It should work if you type it in console as a normal user, but you may not need to - usually the display option just works

if you have it use sux instead of su
