INSTALING STEREO COOT 3D VISION 2 FROM NVIDIA UNDER UBUNTU HARDWARE
CARD: NVIDIA QUADRO 4000. Bought second hand in AMAZON. Other Quadro NVIDIA cards would get the job done as long as they have the 3-pin DIN stereo connector. But this is the cheapest alternative I foundI had to buy the PCI Plate got the 3-pin DIN port separately, it was lost from the second hand card. GLASSES: 3D NVIDIA 2 Also bought Second hand in AMAZON MONITOR: Asus VG248 Nvidia 3D Ready In this case from Ebay Connecting the hardware was trivial. But I recommend to first connect the VG240 using the Dual Link DVI wire and do the setup with this, then you can complicate your life with the second screen. SOFTWARE IMPORTANT ISSUES. The installation is not too difficult if you know a couple of tricks, but I didn´t: - You have to correctly install the NVIDIA driver. I used 390.138 Legacy Linux driver. Not too difficult. Download from here https://www.nvidia.com/en-us/drivers/unix/ <https://www.nvidia.com/en-us/drivers/unix/> Execute as root. You will get this message An incomplete installation of libglvnd was found. All of the essential libglvnd libraries are present, but on or more optional components are missing. Do you want to install a full copy of libglvnd? This will overwrite any existing libglvnd libraries. Answer DON´T INSTALL. Or fully remove libglvnd and reinstall them. See this Web for other tips. https://www.berkhanberkdemir.com/2019/07/24/how-to-not-install-nvidia-driver-in-linux.html <https://www.berkhanberkdemir.com/2019/07/24/how-to-not-install-nvidia-driver-in-linux.html> 3D IS INCOMPATIBLE WITH COMPOSITE EXTENSIONS OF THE DESKTOP manager. I found a LOT of info in this page https://strucbio.biologie.uni-konstanz.de/ccp4wiki/index.php/Stereo <https://strucbio.biologie.uni-konstanz.de/ccp4wiki/index.php/Stereo> 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. I tried to desactivate the COMPOSITE extension in xorg.conf as suggested. Section "Extensions" Option "Composite" "Disable" EndSection But all the Desktop Environments I had miserable failed to start. Then I simply install MATE environment https://www.omgubuntu.co.uk/2014/08/install-mate-desktop-ubuntu-14-04-lts <https://www.omgubuntu.co.uk/2014/08/install-mate-desktop-ubuntu-14-04-lts> Select it and everything worked. Best luck if you want to repeat my experience!
