Adding a little more to Daniel's useful reply...
Since suma is based on OpenGL (a graphics library
for hardware rendering), the natural use will not
usually work because either the GL layers will be
sent over the network for local rendering (VERY
slow), or it will fall back to using software
rendering instead of hardware rendering (again,
VERY slow).
And note that to even begin, the server will need
to have OpenGL libraries installed. Many do not.
You will need to verify that for your remote
server.
Occasionally suma will work reasonably well (such
as served from my laptop to my desktop, but NOT
the other way around for some reason), but that
is not the norm.
One option is to use VirtualGL, which is available
on many current linux systems (I can install with
"yum install VirtualGL" on Fedora 21). That does
require some configuration. But it is not too
difficult.
