Alright.. I have installed PS on my new Ubuntu 9.04 installation, and it seemed to work. But when I start the game, it shows all 2D modeling, but nothing 3D. I believe the problem lies in my 3D/OpenGL, but I have no idea how to fix it since I'm new to Ubuntu. The chat-box works, so that actually proves my theory right somewhat.. I just have no idea how to fix it.
My GFX-Card is an Intel Mobile GM965. It's a fresh Ubuntu installation. It all worked on XP, so if I can't get this to work, I can just go back.. I just prefer Ubuntu (other than this problem) so I don't want to keep switching back and forth.
I hope somebody can help me.
