From 2247ffe954b5a71f82944d23141c836b38716654 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Fri, 18 Mar 2011 10:18:48 -0700 Subject: qemu: warn user if nVidia libGL is detected (leads to qemu segfault) nVidia's OpenGL libraries are known to have compatibility issues with qemu, resulting in a segfault. As different workarounds are required for the different distributions, just warn the user to explain the qemu segfault to follow, and suggest a workaround using LD_PRELOAD.
