Re: [PyMOL] Pymol 2.1 graphics error

Hi Andy,

Great! The -M ("mono") option skips the attempt to detect hardware stereo 
(a.k.a. quad buffered, available with Nvidia Quadro cards and 3D vision).

Did you install pymol with conda? Recently, pyqt=5.9 packages appeared in the 
default anaconda channel, but unfortunately PyQt >5.6 doesn't handle the stereo 
request properly on non-stereo hardware. Downgrading helps (conda install 
pyqt=5.6).

Cheers,
  Thomas

Hi all,

thanks for the responses. The -M option did the trick. What does it do?

Best,
Andy

Hi Andy,

Does it help if you launch PyMOL with "-M"?

pymol -M

If not, can you be more specific about the symptoms? Is it just slow
or do you get flickering, wrong rendering, crashes, etc.?



Are you working directly on the machine's console or over a network to 
a remote X11 server?  Graphics intensive programs which are smooth 
when running locally are often quite jerky when displayed remotely, 
even on a wired local network.

Hi all,

I just installed PyMol 2.1 on my system (Centos 7) and there are 
some issues with displaying any structures.


I get the following error, however I'm not sure whether that's 
what's causing the actual laggy graphics:


 "This Executable Build integrates and extends Open-Source PyMOL.
 Detected OpenGL version 2.0 or greater. Shaders available.
 Geometry shaders not available
 SMAA not available
 Detected GLSL version 1.30.
 OpenGL graphics engine:
  GL_VENDOR:   Intel Open Source Technology Center
  GL_RENDERER: Mesa DRI Intel(R) HD Graphics 530 (Skylake GT2)
  GL_VERSION:  3.0 Mesa 17.0.1
GL_ERROR : 1282"

I'm new to Pymol and Linux so please excuse me if I'm missing 
something.


Thanks,

Andy
