have you looked at /etc/profile{,.d,.env} ?
otherwise, if you really want to know, then strace "su -"

How does this explain why root has a correct $DISPLAY after using "su" or "su -"? BTW: On another box running Ubuntu (too slow for all the compiling), using su doesn't set $DISPLAY for root, which is the behaviour I would expect. Bye...

Hmm, so do I. I hadn't noticed because I have su aliased to sux, but calling su directly now leaves $DISPLAY intact. -- Neil Bothwick If Barbie is so popular, why do you have to buy her friends? signature.asc Description: PGP signature

However, if you su or something, you'll no longer have that environment variable. Generally speaking it should be set to ":0" which is equivilent to "localhost:0.0" or localhost server, display 0, screen 0. if I were in your position I would say: $ DISPLAY=":0" gtkpod -- [EMAIL PROTECTED] mailing list

Am Donnerstag 22 November 2007 schrieb Thufir: > [EMAIL PROTECTED] ~ $ echo $DISPLAY > > [EMAIL PROTECTED] ~ $ So it's unset, which is the reason for the error you get from gtkpod. It doesn't know on which display to open. Try setting it ":0" (export DISPLAY=:0) before you run the command. However, I'm still wondering why it is unset, because the display manager should take care of setting it correctly. HTH... Dirk signature.asc Description: This is a digitally signed message part.

Also helpfull would be the output of "ps -ef|grep X". How do you start X, via display manager (gdm, xdm, kdm,...) or with startx after text console login? Bye...
