#1133 closed defect (nonchimerax)

3D hardware stereo not working chimeraX in RHEL7

Description

I am running on RHEL7, equivalent to Centos7.

Linux paprika 3.10.0-693.21.1.el7.x86_64 #1 SMP Fri Feb 23 18:54:16 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

The Nvidia driver is installed on the system and stereo 3D hardware works fine in pymol. However, it does not seem to run in ChimeraX.


chimerax/bin/ChimeraX --stereo


just gives and error




Traceback (most recent call last):

OpenGL.error.GLError: GLError(
 err = 1282,
 description = b'invalid operation',
 baseOperation = glDrawBuffer,
 cArguments = (GL_BACK_RIGHT,)
)


The graphics card is an FX4800 Quadro.


This was discussed in the ChimeraX users Forum.

I have installed the gcc 4.9 lib in /lib as per web page.

Does anyone have experience with getting this to work on Linux?

thanks

Error suggests it failed to get a stereo OpenGL context. Maybe starting "chimerax --stereo --debug" will say something about not getting the context it asked for.

I improved the ChimeraX stereo code a week ago so that you don't need the command-line option and you can just start ChimeraX with no options and use ChimeraX command "camera stereo". This also might give a clearer error message about why it failed.

If PyMol is displaying stereo then almost surely ChimeraX can to and it is a problem with missing libraries.

If you start ChimeraX without --stereo, what OpenGL info does it give at the top of the log panel? Need to make sure you are getting an Nvidia driver and not Mesa.

FYI, we also have a very simple program that you can use to test hardware stereo at https://www.rbvi.ucsf.edu/Overview/stereotest.html.

No matter how I start ChimeraX and go to hardware stereo, I get the same error. Here is what I get when using pymol2.0.4 that does stereo correctly:

Please send us the output of the glxinfo command. That will tell us more about your OpenGL setup and help us figure out what's going on.

Update::::


Hardware stereo works on the following system:


RHEL7.4 ; P5000 Nvidia driver 384.111


I can start ChimeraX then go to

camera stereo

and I get the system box saying 'enabling stereo' and it goes into hardware stereo. Unfortunately, rotations and incredibly SLOW. In fact virtually impossible and not useful for display. ? why this is?

Linux owsley 3.10.0-693.11.6.el7.x86_64 #1 SMP Thu Dec 28 14:23:39 EST 2017 x86_64 x86_64 x86_64 GNU/Linux


The other system is old, 8 years, and has a FX4800 with 340.104 driver.


Still searching for Good 3D stereo so the professor can teach from ChimeraX. It has superb graphics.

Also as I suggested before, please start ChimeraX without stereo and report the OpenGL info it gives at the top of the ChimeraX log panel.

in reply to:  8 ; comment:8 by goddard@…, 7 years ago

If it is incredibly slow that is almost certainly a graphics driver issue.  I use ChimeraX quad-buffered stereo on a Quadro P6000 on Windows 10 and it is very fast on 100,000 atom structures.  I don’t know about the linux drivers.  Try ChimeraX command “light simple” to turn of the ambient occlusion lighting and see if that makes it faster.  Only a more capable driver will fix slow rendering.  Such a driver may not exist on Linux.

For the Quadro FX 4800, that card came out 9 years ago it is not surprising there is trouble with it.  As it says on the ChimeraX download page: "
We recommend using computers three years old or newer for ChimeraX because it employs several graphics features that require or work best on a recent system.
Although programs designed 20 years ago like Chimera and PyMol might work fine in stereo on 9 year old graphics, ChimeraX is coded for modern OpenGL, such as requiring a core OpenGL context (those old programs use a “legacy” context).  You might want to try Chimera instead of ChimeraX if you need stereo to work on that old system.

in reply to:  9 ; comment:9 by kenneth.satyshur@…, 7 years ago

Thanks. I tested it also on a new computer P5000 Nvidia 390.48, and it runs fine. There is not delay in rotation in 3D stereo. Very impressive display. Whish it worked for old systems too. I have 4 of them.

More updates. I have been running on RHEL7.4 with FX4800 Driver 340.106. It will do stereo in Gnome classic or new Gnome. Rotations are slower than on the P5000 with 390.48. However they do rotate in stereo. However, when I resize the window, chaos reigns. The whole desktop begins to flash in and out. Going to mono does not help. No rotations are possible. In fact I need to logout and back in to kill the behavior. I am sure it is the Gnome desktop. When RedHat went to 7, they broke the nice stereo-in-a-window that runs in version 6 Desktop. Now it is stereo in a desktop, and the whole login is subject to stereo flashing, even if in a desktop that is not displaying stereo. We have have sent many re

many requests to both Nvidia and RH but they don't seem interested in fixing stereo problems. I have been forced to keep old RHEL 6 systems because they will do stereo in a window and we need this to do research. I think that all this will end up in Win since there seems to be a bigger audience there (gamers?). Too bad.

Resolution: nonchimerax
Status: assignedclosed

I am not surprised by your experience. We have quad-buffered stereo running at our lab using a Quadro P6000 and Windows 10, and also Windows 7 and an AMD FirePro W7000. We spent the last couple years trying to get stereo to work on Windows 10 with a variety of work-station graphics cards, and only succeeded a month ago. I think Nvidia and AMD have zero interest in quad-buffered stereo in a window, there is no money in it. If you can get it to work on any new system you are lucky. It is probably more likely to work on Windows than Linux.

Also, to be clear, we do support old legacy graphics systems with our next generation ChimeraX program, this hinders development. For older computers use our older program Chimera. The ChimeraX download page advises to use hardware no older than 3 years.

For stereoscopic visualization we put most of our effort into virtual reality headsets for ChimeraX and I suspect the sequential stereo technology is more dead than ever because of competition of limited engineering resources from VR.

If no one is interested in 3D stereo, VR is even less useful.

I don't think the poor support from Nvidia and AMD for stereo glasses has anything to do with what is useful, it is about what is profitable. Possibly the current generation of VR will also not be profitable and stop working in future drivers from these companies.

I meant to say in my previous message we do not support legacy graphics. We don't have nearly enough funding to try to solve problems for hardware that the companies who made the hardware no longer support.

Sorry I don't have a good solution for you.

That's ok. I appreciate all the hard work that is being done to make better graphics. We will just leave legacy devices for

the older versions. Maybe the OSF people will pick it up as a challenge.
