No. You are using a distribution which has chosen to stop supporting
the device-specific drivers and instead use the "generic" modesetting

I would not recommend doing this, but as with so many things in the
world, nobody really cares about that.

Use this guide to put separate monitors on separate X screens:

Just leave out the Xinerama enable bit.
