In compare with kernel up to 2.6.27 (because I used Ubuntu, Mandriva), 2.6.33 looks:more brighter, may be more contrast, especially white, it is definitely more brighter although I stated xgamma 0.75. But biggest problem is that colors of the picture are not solid, stable - they are somehow blinking or flickering. Sometime I think may be back lights of LCD panel works different. And after hour or two eyes start notice it, it is looks like colors is not constant, they always changes, little bit but they are "playing".

Dear All.

At last, I found the problem - it is new kernel 33 and 34, I took them from Fedora.
I put them to my OpenSuse 11.1 (27 kernel) and boot it up.
Picture of the screen became unusable. And it is not Xorg with its drivers, because except of the kernel everything from OpenSuse 11.1 - it is kernel.
I do not know how it works with other GPU (intel or nvidia), but mine i915GM shows awful screen.
I know what is wrong with picture - colors of the pixels. They are not static, they change. Little bit, but change. It became more noticeable when I just reboot. For example white - it is white, but it changes around white, and as color is brighter it is more annoying.
May be I am wrong about all of it, I for sure - I am not going to use 33 and 34 kernel with i915GM.

Thanks everyone.
