I installed TV on Ubuntu 16.04 (Dell laptop). It works fine with GUI (lighdm service) started, when accessed from Windows 7 for remote control.
But when I try to get acces to headless config (no lightdm service started) I just get an empty black window and can't get acces to a prompt message for login.
I tried various keys composition (Ctrl+Fx or just Fx or Shift+Ctrl+Fx) without success (Ctrl+Fx is the normal to acces to VTs with this distro).
I think framebuffer config is ok as I didn't get any error and the TV logo displays in the laptop screen as soon as the connexion between the 2 machines is done.
Any idea?
