Support for stereoscopic output in DRI?
Hello! According to one or more sources on Google, Linux now makes it possible to use LCD shutter to get stereoscopic graphics in certain games and with certain graphics cards. However, there are certainly other interesting methods of outputting stereoscopic graphics, such as outputting to two different outputs (such as two different projectors with different polarising filters), combining the red channel of the left frame and the green and blue channels of the right frame to create an anaglyphic image that can be viewed with 3D glasses and so on, and it would be really interesting to see if these methods could be used to output OpenGL graphics. Even more so with the arrival of 3D TVs and monitors, it would be interesting to be able to use their stereoscopic capabilities with existing games and applications. I've seen two pieces of software, one for Linux and one for Windows, and it seemed like what they did was intercept OpenGL commands and render two separate images at slightly shifted (user-specified?) angles or viewpoints, one for the left eye and one for the right eye. If the effect could be achieved more or less reliably in all applications, stereoscopic output could be achieved in a wide range of games even today. At any rate, I was wondering if something like this has ever been attempted, or implemented, in DRI? Best regards David J. Oftedal - Take Surveys. Earn Cash.

[Bug 10471] New: Video card shuts down after a random period playing WoW

I cannot login again via a serial console from a remote machine because the keyboard has stopped responding, although there is no evidence of any kind of "oops". Alt-Sysrq-S, Alt-Sysrq-U, Alt-Sysrq-B work, so the kernel is obviously still running.

I first noticed this problem with the March 24 git mesa, shortly before the glsl merge. (NV is still broken, BTW.), and up until last night I thought that I had fixed it by backing out to the March 13 version.
