You are trying to run it remotely, logging into work from home (or
Normal 2-D X is a network transparent protocol -- it will work over the
network just fine, as long as your network bandwidth and latency are low
enough, and you have permissions set to allow it.
3-D, OpenGL and the like, however, use direct-rendering. They require
that you be working on the same machine, due to the additional hardware
requirements of 3-D. You can't forward OpenGL applications using X
forwarding, as you can with 2-D apps.
There is, however, a workaround. Rather than using X forwarding, use
something like VNC. This isn't quite as efficient, but it works if the
connection is fast enough. There are several VNC choices in the portage
tree. I don't have a use for remote desktop services, so I couldn't tell
you how they differ or which works best.
