Open Stack

Hi Clark,

you were on the right track with the DISPLAY variable. I had some  
other stuff on the plate and today I started a new approach. Long  
story short, I have an alias for ssh in my bash profile (our admin set  
that up years ago) which hasn't bit me until now:

alias ssh='ssh -X'

This seems to work fine on Leap 15.2 and Victoria, though, but I'll  
just need to make sure not to use the alias on Ubuntu, I guess. Maybe  
I'll remove the alias entirely.

Thanks!
Eugen
