Cannot paste when ssh into a headless server

[Chunji Wang]

Thank you for this awesome project!

I noticed #11 and #15 but they both involve docker. I set h-m-m up twice, one in a x64 Debian, the other in a raspberry pi. I cannot paste in any of them. The error says Error: Can't open display: (null). I think the reason is that both servers have no display.

a61e4ac may help. Otherwise, I'm not sure if there's anything else possible. But let me know if you could think of anything else :)
