Your right I rebooted and I still have the problem, after running commands
below, I can still no longer get konqueror to give me write privileges

I googled the line below and it's all over the Internet, kde, in Suse, Ubuntu, Fedora and real bad in Ubuntu, no one seems to have a fix for the problem. But a whole lot of guessing.
I have two new $Windows users I want to install Kubuntu this week, but with this problem ?
I guess I will try to reinstall and see if I have better luck.

Error: "/var/tmp/kdecache-mickey" is owned by uid 1000 instead of uid 0.

Debian based systems have 1000 as first uid, see /etc/adduser.conf

su or su - is not sufficient, you need to have the correct security-cookie which belongs to "user" (that started the session manager) and is in .Xauthority
As root has full access to the filesystem, he can access /home/user/.Xauthority.

So one of these should work:

$ su or su -


# xauth merge /home/user/.Xauthority
or
# export XAUTHORITY=/home/user/.Xauthority
or
# cd
# ln -s /home/user/.Xauthority

This last method will stay on reboot.


Take care when you run as root!

root@mickey-desktop:/home/mickey# xauth merge /home/mickey/.Xauthority
root@mickey-desktop:/home/mickey# export XAUTHORITY=/home/mickey/.Xauthority
root@mickey-desktop:/home/mickey#

Both commands ran, but what path were you "cd" to before running ln -s ?

without parameter, cd brings you to $HOME

you have seen that there is an 'or' between each line, one is sufficient.
and did konqueror start then?

here it works (tm)

No,
I have other errors also poping up , I'm just going to pull a $Windows
and "Format c:" and reinstall Kubuntu , this was a new install with all these errors.
Thanks for your help.

Don't have anymore ideas. Reread through the post and notice it was kubuntu. Just thought it was Fedora based on sig.

no , I have Fedora 7 on one of my boxes , and don't have any problems
with KDE and SU.
I noticed on google that someone with earlier version of Fedora was having that problem.

The update for "kdesu" just came out yesterday or today and fixed this problem.
Isn't Linux Great, these bugs get fixed fast, unlike $Windows.
