[GE users] Libraries present on execution hosts.

Hi,

can you try to login to a node by hand and try to start a X-Session with 
output to your login node? Then we know, that it's working in principle.

export DISPLAY=bras:0
xterm

or so. We need at least some X-libs on the nodes (and a running X-server 
on bras to connect to).

Cheers - Reuti
