The configuration setting you changed is what’s causing it to print a lot of information. That information isn’t a sign of trouble, it’s what you asked for by setting that flag.
As for why it started working - no idea. As for why it has trouble with multiple render targets under linux - again, no idea, but everyone has that problem.
I’m on ubuntu gutsy, same card (Nvidia geforce FX 5200 card), and Render-To-Texture works great for me. I’ve had that problem before, and I recall I fixed it by disabling Xgl.
Mine didn’t have that file, so I created it, restarted, and still nothing … Also on the Media Player example, I get an OpenAL support is not enabled, cannot proceed. Are the two related?
Have you tried installing the tool envy to update the latest nvidia drivers, or have you used Gutsy’s system? I ask this since both systems use different drivers.
The OpenAL problem is not related. I recently added support for OpenAL audio, but I then discovered that OpenAL under Linux is buggy as hell. It was so crashy that I just had to disable it entirely. Unfortunately, the media player requires OpenAL.
I would be trying harder to make it work, except for one thing: I’ve noticed that there’s a team of programmers working really hard to get OpenAL in shape. They’ve been making leaps and bounds recently. I figure if we just give it a few months, they might very well get the problems sorted out.
