twl doesn't start (D-Bus-Type Error)

[M.T.]

I installed twl and tried to run it. But it terminates with this message:

What do I have to do in order to get it running?

I use Ubuntu Karmic Koala.

How did you install it?

[M.T. (morro1)]

I downloaded the tar-gz-archive. Then I ran "setup.py".

By the way: When I tried to use the deb-package it didn't work. I don't know exactly why, but it's possible there was a problem with my Ubuntu.

[Isaiah Heyer (freshapplepy)]

The problem with installing from setup.py instead of from a deb is that it won't install all the dependencies for you.
What was the error message when you tried to install from a deb? Were you using the karmic one and not the jaunty one?

[M.T. (morro1)]

No, it was setup.py. May you tell me needed packages? It's not mentioned iin the readme, is it?

[Isaiah Heyer (freshapplepy)]

python-gtk2
python-gnome2
python-metacity

[M.T. (morro1)]

I have got all these packages installed but it doesn't work?!

[Isaiah Heyer (freshapplepy)]

I do not know what the problem could be. I installed twl from the same archive you did in a fresh 9.10 install and it worked. There must be a problem with you system.
