Some G450 dual-head problems

["Byeong-Jun Park" <BPark@computer.org>]

I use Maxtrox G450 dual-head whith
Samsung Syncmaster 950NF (First screen)
 and 17Gli (Second Screen) Monitors

My working environments are
Sid,  X 4.0.3 
I have two problems.

1. I can not apply gamma correction value online
  to screen 1 (second monitor) with xgamma utility
  ( xgamma -screen 0  ...  good work but
    xgamma -screen 1  ...  no change )
 and Anyone knows gamma correction widzard running on X ?

2. glx not work.
   If I turn on glx module,
  X hangs up with message,  "Can not find /dev/nvidia0"
 I have had nvidia geforce2 MX, but now it is removed
 and I remove nvidia-glx package.

Thank you for your reading this message..  ;-)
