Playing terraria on Ubuntu - Graphic card driver needed?

I'm trying to get Terraria working on my Ubuntu notebook (Xubuntu actually). I followed this guide and after hours of struggling I finally managed to install XNA, and .net and all the Microsoft stuff. But after starting the game, it crashes with an error - No suitable graphic card found. When I checked this list I saw my card (Intel GMA 945) isn't on the "not working" list, but similar cards are. But the fun part is, that there was Win XP before on that machine, and Terraria worked there.

Do I need to update the graphic driver somehow, or override the Ubuntu's default one?

If this question is more suitable for ubuntu stackexchange forum, please migrate it, I had doubts where to post it.

Intel Cards are known for having bad OpenGL Support. And on Ubuntu, you will always use OpenGL as backend.

What you need to do is to get accelerated graphics drivers for this card for ubuntu: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=13815&ProdId=2301&lang=eng&OSVersion=Linux*&DownloadType=

Try installing those and check with glxgears if you get acceleration.

Then Terraria might work.

No promises though.
