Hello,

I am having difficulty configuring monitor gamma under Debian Linux Sarge (now the stable release). My self-compiled kernel from the Debian Source package works and supports the chipset - version 2.6.10-6. It's the xserver-xfree86 that is not working. I'm using the i810 module there - no i830 module available. I also tried the same with original linux kernel 2.6.9 that has only i810 support - and still I can't adjust the monitor gamma with kgamma.

Here's my XF86config file and output of dmesg and lspci:

# XF86Config-4 (XFree86 X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the XF86Config-4 manual page.
# (Type "man XF86Config-4" at the shell prompt.)
#
# This file is automatically updated on xserver-xfree86 package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xfree86
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands as root:
#
# cp /etc/X11/XF86Config-4 /etc/X11/XF86Config-4.custom
# md5sum /etc/X11/XF86Config-4 >/var/lib/xfree86/XF86Config-4.md5sum
# dpkg-reconfigure xserver-xfree86

I actually have an Intel Extreme Graphics 852GM 64MB video card. The screen looks very pale, and the video look very bright. I had to adjust contrast in xine video player to see the images properly.

Does anyone know how to fix this? I tried a lot of things now and nothing works.

Thank you for your help.
