I was attempting to run a command spadmin which is used to set up printers and fonts in OpenOffice. When I run it a super user, it returns the error:

XLib: connection to ":0.0" refused by server XLib: No protocol specified

/opt/OpenOffice.org/program/spadmin.bin x11 error: Can't open display: :0 Set DISPLAY environment variable, use -display option Or check permissions of your X-Server (See "man X" resp. "man xhost" for details)

I read the man pages, and toyed with the -display :0 option on spadmin, but got the same error. I then tried running "xhost +local" and "xhost +" (no network connection, no dialup access) and received the same two XLib error lines listed above. So, it looks like I've got a problem with my X Server configuration, but I can't seem to find anything about how to fix it. Also, I didn't glean from the man pages how to check the permissions of the X-Server as suggested in the error message. Any thoughts on how to fix this?

Hi Mr. Lugg, 1) as a regular user (who will su or sudo later) run: 'xhost +local:local' 2) now 'su' or 'sudo $foo' 3) The program run as super user will then work on the local X display 4) You may place 'xhost +local:local' in your favorite xinit script as well. Please note that using xhost is horribly insecure esp. if you are using a mutli-user system with more than one remote user as any remote user may now access YOUR display inc. recording your keystrokes if they are knowledgeable.
