Reptier Host on Raspberry Pi 2 without screen

i've installed the Repetier Host on a Raspberry Pi 2 with Debian Linux. I use the Raspberry only via TightVNC and without a Screen.

At starting the Host there is no Splash Screen, but the CPU is working... then i see a task of Reptier Host short - then it closes.

Here is the console text:

pi@3Dprinter ~/Downloads/RepetierHost $
Could not set X locale modifiers
Xlib:  extension "RANDR" missing on display ":1".

Requires this software forcibly a screen?

Thank you


  • Sure it does. It is our gui software. For headless service or a printer please use Repetier-Server which is meant to run from a Raspberry Pi and controlled via browser or Repetier-Host on a real PC with screen.
  • Okay thank you, for your reply!
