[SHR] X forwarding: export DISPLAY?

Hi list and readers,

I am trying to figure out how to export my display when using ssh -Y (or X). 

The only hint I found was a thread (exactly) a year ago (let's celebrate and make 15-8 ssh -Y-day ;-) ): "X forwarding doesn't work" (*)

I have been fiddling with it time and again over the past months, but I still can not get my applications to export to my laptop.

Some things I tried:
- take the whole export DISPLAY in /etc/profile away
- connect only to start the application 
- "old fashioned" xhost + and export DISPLAY on Freerunner

At best (or worst) the application opens on the Freerunner. Then there are various degrees of stranding on the way to the display of my laptop

The output is quite clear:
(vala-terminal:2759): Gtk-WARNING **: cannot open display: 

There is no display set. This is with the default /etc/profile (DISPLAY=:0). I tried setting it manually to point to the freerunner, to no avail. Xauth does not list any displays, while there is a display on my laptop (how handy..)

Any suggestion?

PS: after sending the mail and not receiving it in my mailbox, I delved into that first. It turns out I have been subscribed to the devel-list for years, while I thought I was reading the community list. Also explains why I was surprised at the subjects in the community-archives that escaped my attention by mail. So much for detective skills...
