Fix SDL on evdev hosts (Anthony Liguori)
This patch corrects SDL support on X11 hosts using evdev. It's losely based on the previous patch by Dustin Kirkland and the evdev support code in gtk-vnc written by Daniel Berrange. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6678 c046a42c-6fe2-441c-8c8c-71466251a162
