You are trying to run it remotely, logging into work from home (or wherever)? 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. -- Duncan - List replies preferred.
