[Chimera-users] Batch mode for Chimera

My guess is it is a graphics driver problem.
We haven't updated the software OpenGL driver that is bundled with the
headless Chimera in ages (Mesa 7.6.1), but we have updated Chimera's use
of OpenGL. Chances are that your Linux server has newer version. So
assuming you don't have a graphics driver installed, you should try
moving aside the libGL.so* and libOSMesa.so* files in your
/home/gleb/.local/UCSF-Chimera64-batch/lib directory so chimera will use
the system versions. You might need to install those libraries on your
system. On CentOS/RHEL, they are the mesa-libOSMesa and mesa-libGL
packages. On Debian/Ubuntu, they are the libosmesa6 and libgl1-mesa-dev
packages.
If you have an AMD/NVIDIA graphics driver installed, then you will want
to copy the Mesa versions of libGL.so and libOSMesa.so to your
/home/gleb/.local/UCSF-Chimera64-batch/lib directory. On CentOS/RHEL,
the AMD/NVIDIA installers should have moved the Mesa versions aside
somewhere, so they could be restored with the driver is uninstalled --
it will take some detective work to find them. On Ubuntu, the libGL.so*
files are in /usr/lib/x86_64-linux-gnu/mesa/.
HTH,
Greg
