From 4b56fa058a45b7c804d1a5fcaf7a70db0bd0581c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20P=C3=ADsa=C5=99?= Date: Tue, 1 Jan 2013 21:25:15 +0100 Subject: [PATCH] x11: Bypass SetGammaRamp when changing gamma Recent Xorg has broken dynamic colors setting, so calling SDL_SetGamme() does not have any effect here.
