Re: [ccp4bb] nVidia 3D Vision2 glasses

2020-01-15 Thread Dirk Kostrewa 

Dear CCP4BBers,

I have done a few tests with different desktop environments and 3D 
stereo, recently:


For Gnome3 with Fedora and EL8 (clones), enabling 3D stereo works 
without switching off COMPOSITE in the xorg.conf. Enabling/disabling 3D 
stereo leads to some additional visible switching of the graphics with 
~1 second delay (I assume COMPOSITE is disabled/enabled behind the 
scenes). However, this does not work for Debian Buster, meaning, you 
can't use Gnome3 together with 3D stereo, there.


Interestingly, for the following desktop environments, there is no need 
to switch off COMPOSITE in the xorg.conf, since this can be done during 
your graphical session in the desktop settings. After that, 3D stereo 
works (tested on Debian Buster). Not switching off COMPOSITE in the 
xorg.conf has the advantage that the user may also use Gnome3 for the 
desktop environment.


For switching compositing on/off, please check/uncheck the following 
settings in the tested desktop environments:


Plasma5: Settings -> Display and Monitor -> Compositor -> Enable display 
compositing


MATE: Control Center -> Windows -> General -> Enable software 
Compositing manager


XFCE: Settings -> Window Manager Tweaks -> Compositor -> Enable display 
compositing


I hope that helps.

Cheers,

Dirk.

Which Linux and which desktop?

Attached find a typical functional /etc/X11/xorg.conf file for stereo use from 
a Scientific Linux 7 machine.
The two notable things about this file:
"STEREO" is enabled in the "Screen" section.
"COMPOSITE" is disabled in the "Extensions" section.

With some newer desktops such as Gnome 3 it is not possible to disable 
composite. Try using the XFCE or Mate desktop.

Hi Matthias,


although, Nvidia announced that the final driver with 3D stereo is the 418 
driver, the more recent drivers (at least up to 440) under Linux (CentOS 7.7) 
apparently still support quad-buffered 3D stereo on our Quadro cards. This is 
in line with the 3D Vision End-of-Life 
FAQ<https://nvidia.custhelp.com/app/answers/detail/a_id/4845/~/3d-vision-end-of-life---faq>
 on the Nvidia site.


Best regards,

All modern graphics cards still support 3D vision, but you are correct that 
nvidia is addressing critical issues in release 418 only till April. So if you 
got a new card, you should not run into problems anytime soon. Just make sure 
the card is supported with the new kernel packages before updating and stick to 
the driver release 418. I did so for the last 7 years and just recently had to 
refurbish the card as it was no longer supported by centos 7.7.1908

So, I dont have an alternative yet either..
