Hello, Hi I'd like to open X-applications like the in the example below from an su Terminal, but get an Xlib connection error. I have set up sudo so that: sudo kwrite /etc/fstab works, but how come it doesn't in a normal su Terminal? Thanks, Chris athlon:/home/stoffel# kwrite /etc/fstab Xlib: connection to ":0.0" refused by server Xlib: No protocol specified kwrite: cannot connect to X server :0.0 -- C. Hurschler
