><i> Hello,
</I>><i>
</I>><i> I recently replaced Ubuntu with Mageia 1 on my laptop. Now I'm seeing this
</I>><i> odd issue where I run a full-screen OpenGL application, it behaves
</I>><i> normally, but immediately after I exit the application X.org crashes, and
</I>><i> KDM relaunches X and gives me a login screen.
</I>><i>
</I>><i> I ran the same applications (the same build, even!) on this hardware under
</I>><i> Ubuntu with no problem, so I'm guessing that there's a buggy driver
</I>><i> somewhere in Mageia's X.org packages.
</I>><i>
</I>><i> This appears to be the relevant section in Xorg.0.log where the video
</I>><i> driver gets loaded:
</I>><i>
</I>><i> [ 19466.329] (II) LoadModule: "intel"
</I>><i> [ 19466.330] (II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so

</I>><i> Has anyone seen something similar to this? I suppose that the next step
