Hi,
I have been using Ubuntu 12.04 with xfce/xubuntu as long as there was no trinity repository available. Now that I have updated to the trinity desktop, there seem to be some problems that I can't figure out. Firstly, I want single-click activation on the desktop and in the file manager, but can't find the place where to configure this.
Then, I am missing the Sleep and Hibernate buttons on logout. 

Both of the mentioned items have been working ok on my previous setup with kubuntu-trinity 10.10.

Anybody have some hints how to rectify this?
Thanks,
Mike
