Displays
 

I have a Lenovo T430 notebook, attached to which is a 36" TV as a monitor. With other Linuxes, I can use Displays to turn the notebook display off. How do I do that with XenialPup64?

Doesn't FN F7 hardware switch them??

I'll try it, but at this point both monitors have the full complement of stuff and are mirrored. The mouse works on both simultaneously.
