You are trying to run it remotely, logging into work from home (or |
| 10 |
wherever)? |
| 11 |
|
| 12 |
Normal 2-D X is a network transparent protocol -- it will work over the |
| 13 |
network just fine, as long as your network bandwidth and latency are low |
| 14 |
enough, and you have permissions set to allow it. |
| 15 |
|
| 16 |
3-D, OpenGL and the like, however, use direct-rendering. They require |
| 17 |
that you be working on the same machine, due to the additional hardware |
| 18 |
requirements of 3-D. You can't forward OpenGL applications using X |
| 19 |
forwarding, as you can with 2-D apps. |
| 20 |
|
| 21 |
There is, however, a workaround. Rather than using X forwarding, use |
| 22 |
something like VNC. This isn't quite as efficient, but it works if the |
| 23 |
connection is fast enough. There are several VNC choices in the portage |
| 24 |
tree. I don't have a use for remote desktop services, so I couldn't tell |
| 25 |
you how they differ or which works best. |
