WIP Stereoscopic 3D support for half/full SBS, over/under, etc

First of all, I'm running Gentoo, kernel-3.13.2, xf86-video-intel-2.99.909, xorg-server-1.15.0, xbmc-git on i3-3220T CPU with builtin graphics HD 2500. The box is connected to Epson EH-TW6100 FullHD 3D projector.

I have also installed intel-gpu-tools from freedesktop git. The testdisplay -3 -i output: http://pastebin.com/526Kkxjf
I can see that my display switches to 3D mode when running testdisplay utility.

I tried to launch xbmc and run a H-SBS 1080p movie. Xorg log file indicates following detected modelines: http://pastebin.com/iXUfsgpx
Now, when I run the movie, I tried using the side-by-side mode, however the display does not switch to 3D mode automatically and I have to do that manually. I also tried the "Hardware mode", but then I get a 2D picture and display does not switch modes. StereoscopicsManager reports correctly that the movie is 'left_right'.

Is xbmc-xrandr supposed to switch to the correct mode when running the movie? As far as I understand this is either intel driver not reporting 3D video modes to the xorg server or either xrandr not detecting them correctly. Any advice?

Side by side mode will not automatically change your TV mode unless your TV supports autodetection. I'm not sure of any TVs that can autodetect SBS or TAB formats.

The hardware mode should work as long as 3D is configured correctly in your OS. I don't use Linux for this purpose so I don't even know if it's possible. It would have to be the Intel Tru3D I guess because NVidia 3D Vision only works on DirectX.
