I created a new user with useradd but I get X errors like "cannot open
display" and "cannot connect to X server" when I try to run X apps as
the new user. I've tried restarting with the same results. Does
anyone know why this is happening?

Is the user in the video group?

Yes, I should have said that.

How have you set up the X session for the users? Is it specified,
e.g., in /etc/env.d/90xsession or in some user-specific configuration
files that only the other one would have?

Does anything exceptional appear in Xorg.log?

(As you can notice, I'm just guessing and shooting in the dark here.)

Have you tried strace? It'll help tell what the app is doing just
before the "cannot open ..." message is displayed.

Are you also using X as yourself at the same time newuser is trying
to use X?
