[GNC] X Forwarding starts session on remote machine?

[Andrew Clark]

WAYLAND_DISPLAY isn't set:

aclark at discus 0 ~ $ env | grep DISPLAY
DISPLAY=localhost:10.0
aclark at discus 0 ~ $ env | grep WAY
aclark at discus 0 ~ $ env | grep GTK
aclark at discus 0 ~ $


Which is why I was confused as to how it was finding the wayland server.

Setting GTK_BACKEND=x11 does work though.
