See:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-driver-ati/+bug/152312
Following an upgrade from Feisty on Kubuntu, the display now appears too washed
out such that "greyed-out" text is invisible in most colour schemes (the text
in this window is only just visible!). No amount of adjustment of the monitor
controls will bring the display back to it's former state under Feisty.
Altering the gamma setting in /etc/X11/x.org.conf or via xgamma to a value of
about 0.4 - 0.5 will improve matters slightly but this was not required in
previous releases.

I installed the "ubuntu-desktop" meta package and got the same results under
GDM/Gnome desktop.

Hardware is a Asus Pundit-R with onboard ATI Radeon 9100 IGP

x.org driver is "ati"

I can confirm this bug also following a recent network upgrade from Feisty to
Gutsy. Moreover, the auto adjust button on my Polyview V293 LCD adjusts nicely
then is immediately over ridden.

Note the Gutsy xorg packages used:
Package xserver-xorg-core
   * gutsy (x11): X.Org X server -- core server
     2:1.3.0.0.dfsg-12ubuntu8: amd64 i386 powerpc
Package xserver-xorg-video-ati
   * gutsy (x11): X.Org X server -- ATI display driver
     1:6.7.195-1ubuntu2: amd64 i386 powerpc

Compared to Feisty packages:
Package xserver-xorg-core
   * feisty (x11): X.Org X server -- core server
     2:1.2.0-3ubuntu8: amd64 i386 powerpc
Package xserver-xorg-video-ati
   * feisty (x11): X.Org X server -- ATI display driver
     1:6.6.3-2ubuntu6: amd64 i386 powerpc

Using the gutsy VESA driver fixes the washout problem at the cost of
poorer resolution.
The same system has no problem running current Debian Sid with
xserver-xorg-video-ati 1:6.6.6.193-3 and xserver-xcore 2:1.4-3.

I note that the 1:6.7.195-1ubuntu2 is from Debian experimental [ !?] which has
been updated since due to this bug which may or may not be relevant:
