xrandr extensions as normal user

[Pietro <p.alfa@email.it>]

Hi,
I've searched the archives for analogous problem, but found nothing, so
forgive me if the question has already been asked!
This is the problem: if I run startx as root the xrandr extensions runs, but
if I run startx as normal user they do not run:
[pietro@gandalf pietro]$ xrandr 
Xlib:  extension "RANDR" missing on display ":0.0".

Any suggestion? I have X from the latest SID except for xlibs from testing
(the bug with alt+tab). I use nv driver (not the nvidia's one).

Bye bye,
Pietro.
