This should be enough to get stereo working. However, note that there is a major issue on linux with window compositing causing stereo images to display improperly. This is a problem with the window display manager, and is not inherent to Xorg or NVidia. If you try to turn on stereo in Coot in a display manager that makes use of the Xorg compositing extension (e.g., Gnome3, or Unity in Ubuntu) then what you will see when you activate hardware stereo is a slight rotation of the view, but stereo remains disabled. In order to get around this problem, you must use a display manager that does not make use of compositing as part of its eye candy. This author has found the MATE desktop to work quite well for this purpose (and may in fact be one of the few that still does not use software compositing by default). Note that you ''do not'' need to disable the Compositing extension in the Xorg configuration file to make this work -- this will allow you to switch back to Gnome3, Unity, etc when you don't need stereo if you prefer! Not disabling the window compositing extension globally allows for a more flexible setup depending on your preferred workflow. | This should be enough to get stereo working.

The update of RHEL7 to 7.6 broke our /etc/X11/xorg.conf . It needs now | |||

The old version still works with KDE, but no longer with MATE. Thanks to Dirk Kostrewa for pointing this out! | |||
