Subject: [PATCH] connected but off screens cause breakage

I often have my laptop connected to my main large screen, however I usually prefer the laptop screen to be off.

If this is the case the window ends up super tiny (probably 0x0).

I have added a tiny bit of `grep` to stop the connected-but-off screens appearing.
