Description Maxime R 2011-11-18 16:00:56 UTC

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

What version is the 32-bit libdrm?  It sounds like it's out of date (but the 64-bit version is up-to-date).

$ dpkg -l |grep libdrm

Also I noticed that the the /usr/lib32/dri/ files are the old ones provided by ia32-libs while the latest versions are in /usr/lib/i386-linux-gnu/dri/.

Please make sure you have no local packages installed and report this to your distribution.

Comment 4 Maxime R 2011-11-20 09:23:26 UTC

Ok, thanks! Keep up with the good work!
