Title:
  [xorg-edgers] 32bit OpenGL applications fail to load i965_dri.so

Status in “libdrm” package in Ubuntu:
  New

Bug description:
  Attempting to run a 32 bit opengl program falls back to software emulation.
  I've tried that with Google-earth, Unreal Tournament and a small OpenGL demo.

  I'm using the Ubuntu 11.10, 3.1.1 kernel and xorg-edgers ppa (2011-11-18 git
  version of the graphic stack).

  Using LIBGL_DEBUG=verbose, i consistently get the following errors :

  libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/tls/i965_dri.so

  I reported the bug here
  https://bugs.freedesktop.org/show_bug.cgi?id=43081, appears it's a
  packaging problem.

  In fact, 32 bit applications call old libraries in /usr/lib32/ (which
  are provided by ia32-libs) instead of the latest version in
  /usr/lib/i386-linux-gnu/

  Eventually found that launching those programs with
  LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/ temporarily solves the
  problem.
