1133	3D hardware stereo not working chimeraX in RHEL7	kenneth.satyshur@…	Tom Goddard	"{{{
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):

 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
