startx problem - display 0 already active?

[viniosity]

I'm installing X for the first time on a brand new Gentoo box (nvidia GeForce3 card w/ nforce2 chipset). I followed the desktop guide by doing an emerge sync, emerge xfree, and then doing an xf86config, etc. but when I get to the startx point I get this error:

Your free to remove the lock file. It wont hurt anything else.

If your unsure about your configuration check out this. Start with a minimal configuration to make sure the basic settings are correct before fudging around too much.

Edit: You did emerge and configure a window manager as well, right?
