NX --> X11 Questions...


I am using NX client to remotely access a RHEL 5 box.


When I log in to the RHEL box as myself, I can then run xclock ok.
When I "sudo su -" or "su user" and run xclock I get:

Xlib: connection to ":1000.0" refused by server
Xlib: No protocol specified

Error: Can't open display: :1000.0

Probably a simple fix but I am very green when it comes to X11
and would appreciate all suggestions.

Thanks,

Ray

You have two different users. One that started the desktop and one that's starting an application hat uses the desktop. When you have two different users, permissions/privileges are likely at issue. The second user needs permission to use the desktop started by the first user.

That doesn't solve the problem, but I wanted to point it out just so you have a reference. So, what you need to do is issue an xhost command. An example I found online gave this:
Code:
xhost +local:username
It's been a while since I messed with it, but I don't think issuing that command is a permanent change. You might have to issue it each time you start a deskop. You'll need to find an appropriate X11 startup file to make the change permanent (if that's what you want).
