Help me get rid of these flat colors (xorg wise) [solved]

As the topic says, time has come to install Arch on this lappy after first checking in with a fedora 8 t3 live cd.
Now the problem is, Xorg gets the colors plain wrong on Arch. Colors look both too bright (no a real problem I can adjust the brightness of course), but also flat. This really is annoying for things like looking photos.
On fedora the colors look good, but I can't find anything color related they do to Xorg.

Well, basically any hints, tips, calibrating applications, or anything you can up with to get the colors good so this lappy can remain running arch ?

[edit] the videocard is an intel 845gm (same problem with both the i810 and intel driver)

Perhaps is has something to do with your color depth. Post your output from:

xdpyinfo | grep root

# xdpyinfo | grep root

root window id:    0x65
depth of root window:    24 planes

no problem there I guess

I solved it by changing the gamma settings like this

xgamma -rgamma 0.7 -ggamma 0.67 -bgamma 0.6

with the start of the DE.

The colors are now better than ever before

Not an issue at all, but is it possible to get these settings into xorg.conf or does xorg not support it ?

man xorg.conf (Monitor section):

Gamma  gamma-value

Gamma  red-gamma green-gamma blue-gamma
     This is an optional entry that can be used to specify the gamma correction for the monitor.  It  may
     be  specified as either a single value or as three separate RGB values.  The values should be in the
     range 0.1 to 10.0, and the default is 1.0.  Not all drivers are capable of using this information.

I guess I should have looked there (thanks for pointing it out for me).

Sadly it does not work , although one would not say so from the Xorg.0.log

[ronald@Miranda log]$ cat Xorg.0.log | grep gamma
(**) intel(0): Using gamma correction (0.7, 0.7, 0.6)

Could this be because of

man xorg.conf wrote:
