Howto get TTL with checkerboard stereo in Linux
How do I configure xorg.conf so I can get a TTL signal when using checkerboard stereo (stereo option 8)? The ForceStereoFlipping option does not work for checkerboard. The TTL signal only appears if I use stereo option 3. I've tried using older nvidia driver versions unsuccessfully. Here is the relevant portion of xorg.conf along with relevant information from the log file. Any suggestions?
