[CSCMail-Users] Problems Installing

[Richard P. <ao...@ds...>]

Hi,

I've been trying to install CSCMail with the CSCMailInstaller.pl option,
but I get the error message: Gtk warning: cannot open display: at (eval)
line 1. 

Can anyone help?

Richard

You usually get the "cannot open display" error when you're not running
a GUI, or are running a shell session that doesn't have X forwarding.
The best way to check is to see what the $DISPLAY environment variable
contains. For example, when I open a terminal and do

	$ echo $DISPLAY

If it's empty, then that's the problem.

HTH,

Gavin.

Are you running the installer as root? If yes, how did you login? I mean: does
X run under user root as well? If not this might be the problem: you are not
allowed to use another users X-Server, not even if you're root. There is a way
to change that (temporarily, everthing else wouldn't make sense and was a
security issue), but the easy way is to start X as root or start a second X for
root.
