Running X programs as root.


Is there anything wrong with doing the following to run X programs as root:

xauth -f /home/[user]/.Xauthority extract - :0 | xauth merge -
export DISPLAY=:0

Regards,

Greg

It seems like a lot of extra work. Have you tried simply:
Code:
$ su -m
# ./x-app-here
?

That does not work in Slackware.
What I usually do to get X apps to run on my display after su-ing to root:
Code:
echo $DISPLAY                  # you'll be needing this value 3 lines below
sudo -i                        # or "su -" on older Slackwares
xauth merge ~alien/.Xauthority # use your own username here instead of "alien"
export DISPLAY=:0.0            # use the value of DISPLAY you've seen 3 lines before

Eric -
Can you give a quick explanation (or link to some info) of what's different about Slackware's X configuration that prevents anomie's suggestion from working? It seems like I've been able to just su to root and run an X program on other distros, but not Slack.

Erm, what about kdesu (or gksu in GNOME)?

This is because Slackware uses the "su" program that is part of the "shadow" utilities. Other distros probably are using the "su" that comes with the coreutils package, and which knows about the "-m" option.

I never realized there were any differences in the low-level utilities. I assumed they were all GNU-based, and every distro used the same ones. I looked up the man page for the coreutils 'su', and sure enough, its -m flag prevents the environment variables from being reset when you change users. The manpage for 'su' on my Slackware box doesn't include that flag. I also didn't know that the same package (shadow) provides all of the useradd/groupadd/etc scripts. Thanks for the info, Eric.
