nvidia x server color correction gamma setting always back to default after restarting computer

[Hery]

I use Nvidia Geforce 7600 GT. Whenever i set my gamma setting, it always reset back to 1.00 after i restart my computer. I notice it from my LCD screen, it become brighter then before ( because i set my gamma below 1.00 ). But if i open Nvidia X Server Setting, my LCD screen immediately become darker like it correct it self according to my gamma setting. For information My LCD is 17 Inch Samsung SyncMaster 732n+ ( D Sub / Analog Type ) .
It also detected as CRT monitor in Nvidia X server setting (Is it wrong or is it because i have D Sub / Analoc connector and not DVI ?? )
I use 180.44 driver version and UBUNTU 9.04 clean install.

Hi overvi,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

As long as i remember, i didn't change my xorg.conf but i will attach it anyway. Maybe it will help.
Thanks.

I've posted a new version of the -nvidia driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get nvidia-graphics-drivers-180 - 185.18.14 here:
