[xubuntu-users] TDE (Trinity) apps won't open on Xfce desktop

[Nigel Henry]

Xubuntu 10.0.4 with recently installed TDE 3.5.13.2 trinity desktop.

I have some icons for apps on the trinity desktop, but when I'm  in xfce the 
icons are there but clicking on them just opens a desktop config file for 
them. It seems like a path related problem, because when I open the kde 
(trinity) apps in a terminal using the exact path they open just fine.

The path to the kde (trinity) bin files is /opt/trinity/ .

Where and how do I add this path so that I can open them on xfce desktop?

I seem to remember setting the /sbin path in .bashrc on fedora ages ago, but 
have forgotten how I did it.

Thanks for any help.

Nigel.
