[Chimera-users] Problem running Chimera remotely on CentOS7 system

[Greg Couch]

Hello,

I'm preparing a change to the Chimera installer that will workaround 
this problem.  In the interim, you can remove the following libraries 
from CHIMERA/lib, where CHIMERA is the root of the Chimera installation 
tree:
> libgcc_s.so.1, libstdc++.so.6, libgfortran.so.3, libgomp.so.1, and 
> libXss.so.1

That assumes that your system has those libraries installed elsewhere 
and that they are more recent than what comes with Chimera.  The 
libraries are the C runtime library, the C++ runtime library, the 
Fortran runtime libraries, and the X11 screensaver extension library.

I noticed in your error report that your system is using a software 
OpenGL renderer, Mesa.  If you have AMD or NVIDIA graphics, please 
install the proprietary driver from the vendor, www.amd.com or 
www.nvidia.com, respectively.  The proprietary drivers have much better 
performance and are more efficient than the open-source drivers.  If you 
have Intel graphics, then your only choice is the open-source driver, so 
in that case I'd recommend switching to a Linux distribution that keeps 
up with changes in the graphics drivers, like Ubuntu.  The Intel drivers 
are way better than they used to be, but are still undergoing a lot of 
development.  FYI, CentOS 7 comes with Mesa 9.2 and Ubuntu 15.04 has 
Mesa 10.5, need I say more?

     HTH,

     Greg
