Hi.
Well, I don't know really what you wan't, but I remember pain with graphics
and computers. :-)
I see the same error (X Error of failed request....) when I get a kernel
update to my CentOS comp.
That screws up my NVIDIA driver installation, pymol fails, and I have to
reinstall the driver package.
The term "LIBGL_ALWAYS_INDIRECT=1", is controlling something with which
method draws the window.
By OpenGL or by the mesa driver. (Something like that).
The OpenGL is super fast, and mesa driver is slow.
Our shared installation of pymol, means that computers with the NVIDIA
driver works super fast, while
the computers which havent an updated NVIDIA driver is just running slow.
(Pain slow).
If this can help, our execution script for pymol is:
----------------------------------------------------------------------
[tlinnet@tomat pymolsvn]$ cat pymolMPEG.sh
#!/bin/bash
if [ ! -f $HOME/.local/share/applications/pymolsvn.desktop ];
then
ln -s /ourlab/software/pymolsvn/pymolsvn.desktop
$HOME/.local/share/applications/pymolsvn.desktop
