Didn't think of that. You'd think XMMS could warn you about that after clicking 'enable'.
You opened up a can of worms here. I'm using a NVIDIA GeForceFX 5200 video card. I downloaded the nvidia driver, tried to install it, but YAST says I'm using the 'nv' driver. I haven't tried to enable 3D support, however, when I try to configure it In YAST2, it says my card does have 3D accelleration enabled. Then I go into the menu anyway and it says it's not, and asks if I'll allow the system to install the Linux 3D/OpenGL accelleration, which probably isn't as stable as the actual nvidia driver.
Think I should go back and install the nvidia driver?
