Unfortunately this problem is affecting me in Quantal Quetzal as well.
Basically the behavior is the same as the other fellow users are
experiencing: A too light-saturated Desktop Display that cannot be
corrected using any gamma utility.
In the past I could fix this using the radeon.modeset=0

@Andy - that sounds like a different bug. Also I'm not sure whether you
are using a Radeon or not. Please use ubuntu-bug to file a new bug
report.

Should Kernel 2.6.35.1-candela also fix this? It seems to have
catapulted me straight into a different problem, where rather than just

Thanks, but I've noticed that the recent kernel fixes this bug. I am
running 2.6.32-23-generic and I have no problem with default kubuntu

bright-display issue is fixed, however a new issues are introduced by
fglrx. The whole UI is much slower with fglrx. Just as an example, when

The above kernel has fixed this issue for me.
My issue seemed to be slightly different, it was mostly very bright but
depended on what was displayed on the screen. It seemed to be doing some
sort of dynamic contrast - if what was being displayed was mostly white,
the contrast would lower, if what

[R423] gamma bug, display too
I sort of fixed my problem.

(II) RADEON(0): Output DVI-0 using initial mode 1680x1050
DVI-0 is the good one, which works.
DVI-1 has bad colors.
