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

... And this is what gets dumped to Xorg.0.log when the crash happens:

Has anyone seen something similar to this? I suppose that the next step would be to dig through the X.org bug trackers to see if this correlates to any known issue.
Thanks for reading.
