[PATCH 0/1] Fixed GL apps failure on qemux86/x86-64 on Ubuntu 11 with Nvidia GLX driver, Apr1, 2012

[edwin.zhai]

From: Zhai Edwin <edwin.zhai@intel.com>

All,
Previous version of nVidia GLX driver in Ubuntu 10 cause qemu segfault, so we
fall back to Mesa GLX driver if detecting nVidia driver installed. From Ubuntu
11, nVidia GLX driver works well, while previous work around cause GL apps
failure. So this work around is limited in Ubuntu 10 only, and will be removed
in future.

Pls. help to review and pull.

Thanks,
Edwin
