Default Updated 32bit drivers to 256.44 and now I get this.

Hi. I just updated my drivers to 256.44 and now I get this when looking at xrandr output:
xrandr: Failed to get size of gamma for output default

Is this something to be concerned with?

primerib,

Can you please supply an nvidia bug report (see stickies), the exact xrandr command-line you're using, and also the driver version where this used to work, if any? Thanks.

Hi Stephen, stumbled upon this thread after some googling; I was getting this with $ xrandr too. It's probably unrelated to my issue but:
I was looking into xrandr because something broke either in maverick, xorg1.9 or 256.53.
Xinerama Info is not properly working, all my apps launch either in the middle of the screen, or stuck on the right side of my primary screen. My xorg.conf bit:

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "1"
Option "TwinViewXineramaInfoOrder" "DFP-0, DFP-1"
Option "metamodes" "DFP-0: 1680x1050 +0+0, DFP-1: 1680x1050 +1680+0"
SubSection "Display"
Depth 24
EndSubSection

$ xrandr outputs:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 3360 x 1050, current 3360 x 1050, maximum 3360 x 1050
default connected 3360x1050+0+0 0mm x 0mm
3360x1050 50.0 51.0*

This is probably just an unsupported feature in NVIDIA's driver, and not a problem. I believe the gamma APIs were added as part of XRandR 1.2, whereas the NVIDIA driver only supports XRandR 1.1.
