Want to use xrandr, but it says extension "RANDR" is missing

hello!
i have a problem and i don't know why, i think i have everything done to be able to use xrandr (nvidia-settings needs it). but i can't.
that is my problem:
$ xrandr
Xlib: extension "RANDR" missing on display ":0.0".
RandR extension is missing
here is my xorg log:
$ cat /var/log/Xorg.0.log | grep -i randr
(**) Option "RandR" "on"
(**) RandR enabled
(II) Initializing built-in extension RANDR
these are all errors:
$ cat /var/log/Xorg.0.log | grep EE
(EE) NVIDIA(1): Unable to find available Display Device for screen 1.
this is my xorg.conf:
# nvidia-settings: X configuration file generated by nvidia-settings
