Ububntu Jaunty 9.04 video card problems

[bomeatbob]

Hi... I know this topic has appeared in many places but I have yet to find a fix for the current OS I am using. I am using Ubuntu Jaunty 9.04 and am EXTREMELY new at this whole linux thing. I have the game installed and am running into the whole "your video card is too old, or you need to update drivers, or directx is out of date." I am using an ancient pc with a video port on the motherboard, (currently do not know the make but will open her up if need be). This thing has no ports for another video card, (of which I have a few lying around) so I understand if your suggestion is to get out another tower that can support a video card. I am just hoping that there is a nice quick fix to this problem instead of having to rebuild a new tower and to reinstall a new OS. This tower is sort of my Ubuntu experiment so far and I am still in the very early learning stages.

Any help is welcome.

Bring on the flaming for my ignorance!
