SW3DFnx:

Why don't you try an upgrade to Lucid 10.04? It's still a beta, but very stable. When using Ubuntu 8.04 I had problems with outdated video drivers, that were solved after upgrading to 09.10. However, 9.10 wasn't very stable, so I decided to upgrade to 10.04 which you can find here .

SH3D works fine on my computer.
