From 6ebf649d1b87944257fe492e0aef842d1b8debc2 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Mon, 6 May 2013 17:27:09 +0200 Subject: Fix Bug 600 and Bug 721: Adding support for multiple monitors w/ NEWT - Support for all monitor devices and their available modes - X11: Use RandR 1.3 if available - Retrieve information - Changing a monitor device's mode - Support for dedicated and spannig fullscreen - See - TODO: - X11 RandR does _not_ relayout the virtual screen size and neither the CRT's viewport.
