If I su to root and try to run nedit I get an error
root@---------# nedit
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
NEdit: Can't open display

But, if I first run
xhost +localhost
and then go to root and run nedit I'm OK.

In Debian there is some obscure simlink you can make that will solve this...
but I forget what it is. Is there a similar fix for Slack?

Thanks,
Al

Before you "su", use

XAUTHORITY=$HOME/.Xauthority
export XAUTHORITY

Don't use 'su -', just use 'su'.

Better yet, learn how to use vi or, if you have sadomasochistic
tendencies, emacs.

uhmm, in most cases 'su -' results in the desired environment. besides, it
has nothing to do with this issue.

that suggestion is just plain dumb.

anyway, follow the suggestion of exporting XAUTHORITY as another poster
mentioned, or if you're using kde and want it easy: use kdesu.

Yes it does, because it also changes the home directory, so that the
..Xauthority file isn't found anymore. That is what setting the XAUTHORITY
environment variable fixes, setting the path TO the .Xauthority file.

To be able TO connect to the Xserver, the client either needs to
supply the authority key, found IN the .Xauthority file, or the
Xserver has to allow "any client on this machine", which is what
xhost does. But after "su -" the client doesn't know where the
..Xauthority is located, as the home dir has been changed.
