Need drivers for matrox g400

[jbander]

I Need drivers for the linux Ubuntu 11.04 Matrox G400 . I put the video card in and nothing came up on the screen , so I guess there is no drivers of any kind in my Ubuntu 11.04 . So do I have to load the drivers first, using my old card and if it is so, how do I do it.

I ran sudo apt-get install xserver-xorg-video-mga and it said it was already the latest version. so were do I put it so the matrx g400 will reconise it, as it is now when I put the g400 card in nothing come up on the screen except the boot amd bios page then it goes blank.
