I'm having real trouble setting up X11 on a Gentoo box of mine. I have it installed along with the "nv" drivers for my graphics card, but I can only start it up (using startx) as root. If I run startx as any other user it gives me the error "Xlib: connection to ":0.0" refused by server". I've seen people solve this problem using "xhost +user" before, but when I try to do this it just throws me back the error "unable to open display """, which suggests to me that the $DISPLAY variable isn't set up correctly. Am I on the right track? What should I set my $DISPLAY to?
Thanks for your time.
