From 4171d32e6eea47bf2cd160ace0ec3639e10b3aa9 Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Wed, 16 Mar 2011 13:33:32 +0100 Subject: Introduce -display none New option -display none. This option differs from -nographic by not trying to take control of stdio etc. but instead behaves as if a graphics display is enabled, except that it doesn't show one.
