try "su halt"

your login name name dose not become root with su
and there a few programs that will only run for root

try "su -c halt"

"su -" and "su" are very different.

you can mess up a system just as badly with su as you can running as root
for one or two commands su is just fine but more than that I login as root

I agree. As I mentioned in my soap box, I am configuring and testing an eventual HTPC, which requires a lot of administrative work during this stage. In such an environment, I don't have time to play the su game. I just don't care for the religiosity that I am not supposed to work as root.

I agree. With my office box I always log in with a normal user account. Yet frequently during the day I su to root to perform various administrative tasks. Again, the point is that working as root is not risky. Crossing a busy street is far more risky. The point is basic human carelessness and ignorance. Working as root provides no barriers to those everyday human characteristics. Experienced and knowledgeable users know that and move on with life. They don't preach. I don't think twice about typing many commands, but when I type something more complicated I tend to stop and read what I have typed. Again, I just don't care for the religiosity that I am not supposed to work as root.

Usually newbies are the ones who start crying about root. The people who use distros specifically designed for inexperienced computer people seem prone to such behavior. Experienced computer users seldom act that way. The experienced and mature user might offer some brotherly advice, but rarely preaches.

I've been using computers longer than many people at LQ have been alive. Yes, I've done some silly things with computers but no more or less than in other facets of life. I just detest religiosity. What I do with my computers is my business and what others do with their computers is their business. Live and let live.

To get back on-topic.
I get these Akonadi errors about Dbus and QMYSQL (which seems to be installed) and yes, I did remove .kde and .kderc. Logged in as user gives the same errors. The earlier mentioned solutions don't work (there is no /usr/local/share?).

It's a fresh -full- install.
Anyone?

I had that problem in the "root" account but not a normal user account. I solved the problem for "root" by editing a file. The file is under ".local" (that has a dot in front and is hidden). You have to turn on the option to show hidden files in order to see ".local".

The file that I edited for root is this one.

/root/.local/share/akonadi/mysql.conf

Immediately following the line with "[mysqld]" add this line.

user=root

Log in to the root account a few times. I think that I had to let it rebuild the database but it eventually was able to start up Akonadi.

If you have problems with other user accounts I recommend that you rename the "akonadi" folder to "akonadi.old" under ".local/share". If that fixes the problem then you can eventually delete "akonadi.old".

Thanks for the reply, but that doesn't do the trick unfortunately.
Still the same error about not being able to connect to MYSQL server and Dbus.

Solved it. Removed practically all .files and .folders in /home/ and now it works.
