[Dri-devel] Simple example fails w/direct rendering

[Nathan Gray]

Hello,

This is an example from an opengl tutorial that I'm trying out.  If I run it
with LIBGL_ALWAYS_INDIRECT it works fine, but with direct rendering I just
get a blank window.  I'm using the radeon driver from recent CVS (checked
out yesterday anonymously) on a Dell Inspiron 4150 w/Radeon Mobility M7.

Any ideas?

Thanks,
