Unset $DISPLAY when running under mosh

[grep0]

mosh does not support X11 forwarding, but it is still keeping $DISPLAY env. It breaks the programs that work differently depending on X11 presence.

If would be great to unset $DISPLAY in a shell under mosh.

It would be better if mosh could support X11 forwarding, but is this even possible, given the architecture (of X)?

I don't understand why your DISPLAY is set in the first place -- do you have ssh configured to use -X all the time...?

[brmiller]

YES!

Maybe mosh can add the -x option to ssh, to disable X11 forwarding?

It seems that having mosh be in the business of deciding which environment variables should (not) be passed in is extra complexity. For local environments that need this behavior we suggest writing a small wrapper script that replaces mosh-server, unsets the appropriate variables, and then exec's the real mosh-server binary.
