Hello,
I'm a totaly Linux- newbie and new in this forum, so please have mercy!
I just installed Knoppix 3.7 yesterday, because I found it pretty good. I put it on a separate HDD, cause I wanted to avoid any risks for my two NTFS-partitions.
Lilo installed, XP was still running, everything seems to work.
Today I wanted to edit some .conf files, because my epson scanner needs to be activated this way.
I realized, that I had to do this with root-access. For an old DOS-Nerd this is something completely new, so I spent several hours with searching for the right commands.
The .conf-file is owned by root so
This is what I tried:
I open the shell ("DOS-Box")
I type SU and the admins password
I try to start kwrite to navigate to the file and edit it
This is what appears:
pit@Peter:~$ su
Password:
root@Peter:/home/pit# kwrite /etc/sane.d/epson.conf
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
kwrite: cannot connect to X server :0.0
root@Peter:/home/pit#[/color]

I hope it's just me being too silly for that, so please tell me what to do.

PIT
