I have installed xfce4 with success on Crux 3.1 but when I run "startx" (after having run #echo "exec xfce-session" > .xinitrc ) comes an unexpected error message:

"using system config directory "/usr/share/X11/xorg.conf.d

module ABI major version (150 doesn't match the server's version (18)

fatal server found no screens found"

thanks
