Q: How do I enable stereo mode in CentOS?
A: Assuming an Nvidia Quadro4 980 XGL-card.
- Install the proprietary Nvidia-driver.
- Edit /etc/X11/xorg.conf.
- In section Device, add line Option "Stereo" "3".
- In section Extensions, add line Option "Composite" "Disable"
- If section Extensions is missing add a new section "Section "Extensions", add line from §4, and finsh off with "EndSection".
- Add a modeline to enable 120Hz: Modeline "1280x960@120i" 105.68 1280 1312 1712 1744 960 979 989 1009 interlace
- Restart X by logging off and run the 3D-software.
