When you su - you relogin so getting a new environment
I know, that's what I want - I want root's PATH and a few other things set.
I tried with only 'su' but then:
QPixmap: Cannot create a QPixmap when no GUI is being used.
Xlib: Connection to ":0,0" refused by server
A few more errors like that.
users cannot generally use each others display
Now you are completely wrong.
Not being able to do that is specific to Debian. RedHat, Mandrake, Slackware, SuSe..... no problem. Only sound doesn't work, everything else does. (Also works with both xorg & XFree)
This is pretty essential to me, if I can't get this to work I will not use Debian. I need it and I'm used to it.
What do you think, is it related to X or to system? It should be X, since it's the X-server that refuses connection - but the problem is Debian-specific so it should be something in systems configuration?
I can run 2 computers beside each other to try to find the differences, but it would be good to know where to look!
