Problems with su, sudo, root and user
 
This is probably a trivial matter but I am stumped. I have been using ubuntu or a derivative distro and perhaps I grew too used to sudo.
If it matters I am on Slackware 13.37 and xfce4. I was able to adjust sudoers to allow sudo but I am having difficulties running some progs as root. The biggest concern is trying to start thunar as root. It wont run after sudo, su, or su -l. What am I doing wrong?

For GUI applications you should use kdesu.

Or alternatively for when in a root shell:

Code:

# xauth merge ~<username logged into X>/.Xauthority
# export DISPLAY=:0.0

I thought of kdesu but I can;t find it. I assumed it would have been installed during original installation but I dont think so. I looked in the slackware dvd and apparantly it is not in a separate pkg.
Software installation seems to me to be the only difficulty of slackware. Got lazy with apt-get :)

If you are new to Slackware it is strongly recommended to do a full install. Have you done that?
If you don't want to install the KDE packages you can install gksu from SlackBuilds.org, it has the same functionality.

During the install I checked full install. Maybe I should try it again and start fresh.

Stick this in your ~/.bashrc
Code:

xhost +local:root > /dev/null

That did the trick. thank you very much.
I still have a lot to learn with this pkg system and this certainly has me going in the right direction.

For what its worth, I re-installed Slackware, this time leaving out KDE. There is no problem using su or sudo to open thunar or anything else yet.

In its default configuration I would not expect you to be able to start graphical apps as root with su or sudo from a terminal running under your user account. Did you preserve or copy over your ~/.bashrc?

Actually that is without a .bashrc. I was able to start thunar under su or sudo
