I am using nxclient on my Windows machine to connect to a Linux server which is running RHE. I am able to run all programs with GUI correctly. However, when I run the same programs with sudo, I get the following 

error:(SciTE:25243): Gtk-WARNING **: cannot open display: :1066.0

There is no display connected to this machine, so I am gussing nx is setting my $DISPLAY to :1066.0?

problem is that sudo changes you user context to root and root doesn't have a display set. try using kdesu (for kde) or beesu (for gnome) to launch your app

  • Isn't beesu a wrapper around su? I was hoping to find a way that I can use sudo rather than using beesu and entering the root password.

  • What happens if you launch sudo with :1066 as a parameter?

  • I don't think that's a valid argument: sudo :1066.0 SciTE sudo: :1066.0: command not found
