root@Greg-PC:~# mousepad
No protocol specified

(mousepad:2347): Gtk-WARNING **: cannot open display: :0.0
root@Greg-PC:~#

I know there is a work-around for this but considering how rarely I need to do this that I find it easier to remember to login as root if I am doing anything fancy.

You need to read the 'man page' again. This is the format of the 'su' command;

Quote:

su [options] [username]

You would use 'su -'to get the 'root' environment as to this explaination;

Quote:

Invoked without a username, su defaults to becoming the Superuser. The optional argument - may be used to provide an environment similar to what the user would expect had the user logged in directly.

Simply you would choose either '-' to get environment for user, if nothing trails the '-' you get superuser/root. For '-l' or '--login' you would get the login for the user selected.

Quote:

-, -l, --login
Provide an environment similar to what the user would expect had the user logged in directly.

When - is used, it must be specified as the last su option. The other forms (-l and --login) do not have this restriction.

I don't know what I am missing here. Neither "su", "su -l", "su -" nor "su -l -" would allow me to run gui apps as root.

The solution was to edit the .bashrc file as explained by beowulf999.

sudo, however, will.

Code:

repo@cannabis ~]$ xhost +
access control disabled, clients can connect from any host
repo@cannabis ~]$ su -c program

Kind regards

Well.....you really don't what just any client to access from just any host. It is best to specify who and where explicitly. Of course, it depends on how much you are worried about security.

xhost +local:root
