[Chimera-users] Chimera - remote start up issue

[Greg Couch]

Yes, as you discovered, remotely displaying 3D graphics is 
problematic.   Sometimes it works, usually if the graphics driver on the 
remote computer and the local computer are the same (same manufacturer, 
same operating system, i.e., same variant of Linux and version).


In your case, I'd recommend installing the VirtualGL package on the 
CentOS 7 computer, along with a graphics card and its driver. That way 
the 3D graphics are done on the CentOS 7 computer and an image is sent 
to your computer.  VirtualGL is available from the epel repository and 
virtualgl.org.  This is also the solution for nomachine and x2go.


An alternative would be to try the free cygwin.org X11 server, or a 
commercial X11 server, like Exceed 3D.  If either of those work, please 
let us know.


     Good luck,


     Greg
