[PyMOL] Running pymol over SSH and setting LIBGL_ALWAYS_INDIRECT

[Troels E. L. <tl...@gm...>]

Hi pymolers.

I was trying to test our lab pymol installation from home.
But i ran into an error in freeglut, when executing over SSH.
I have found a solution, but is unsure what it does, and if means something
for
speed and 3D rendering.

*When I ran:*
*[software@elvis ~]$ pymol*
*freeglut (pymol):  ERROR:  Internal error <FBConfig with necessary
capabilities not found> in function fgOpenWindow*
*X Error of failed request:  BadWindow (invalid Window parameter)*
*  Major opcode of failed request:  4 (X_DestroyWindow)*
*  Resource id in failed request:  0x0*
*  Serial number of failed request:  33*
*  Current serial number in output stream:  36*
* PyMOL: abrupt program termination.*

I found a solution here:

http://unix.stackexchange.com/questions/1437/what-does-libgl-always-indirect-1-actually-do
http://ubuntuforums.org/showthread.php?t=1682020

*I then changed the pymol exexution script.*
*
*
*[software@elvis ~/pymolsvn]$ ls*
*modules  pymol  pymolMPEG.sh  pymolplugins  Pymol-script-repo
 pymolsvn.desktop  svnfreemol  svnpymol  updatepymol.sh*
*[software@elvis ~/pymolsvn]$ cat pymolMPEG.sh *
*#!/bin/bash*
*if [ ! -f $HOME/.local/share/applications/pymolsvn.desktop ];*
*then*
*ln -s /sbinlab2/software/pymolsvn/pymolsvn.desktop
$HOME/.local/share/applications/pymolsvn.desktop*
*fi*
*
*
*export FREEMOL=/sbinlab2/software/pymolsvn/svnfreemol/freemol*
*export PYMOL_GIT_MOD=/sbinlab2/software/pymolsvn/Pymol-script-repo/modules*
*export
PYTHONPATH=$PYTHONPATH:/sbinlab2/software/x64/lib64/python2.6/site-packages/PIL
*
*export
PYTHONPATH=$PYTHONPATH:/sbinlab2/software/x64/lib64/python2.6/site-packages/lib-tk
*
*export
PYTHONPATH=$PYTHONPATH:/sbinlab2/software/x64/lib64/python2.6/site-packages/lib-dynload
*
*export PYTHONPATH=/sbinlab2/software/pymolsvn:$PYTHONPATH*
*export
PYTHONPATH=/sbinlab2/software/pymolsvn/Pymol-script-repo/modules:$PYTHONPATH
*
*export PYTHONPATH=/sbinlab2/software/pymolsvn/Pymol-script-repo:$PYTHONPATH
*
*export PYMOL_PATH=/sbinlab2/software/pymolsvn/modules/pymol/pymol_path*
*export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/sbinlab2/software/x64/lib/pymollib
*
*export LIBGL_ALWAYS_INDIRECT=no*
*
*
*/usr/bin/python /sbinlab2/software/pymolsvn/modules/pymol/__init__.py "$@"*


It now works fine when running pymol.
And it also works when i set: *export LIBGL_ALWAYS_INDIRECT=yes*
*
*
But what is the fastest solution, so pymol can use Direct rendering?
Locally, when sitting at the computer and over SSH.
