Hello everyone!!

I experience a strange problem on my Asus X5dij laptop with Intel 4 Series Mobile chipset( Intel GM4500 Video card).
The problem is that my monitor's refresh rate seems to be low, as I see some sort of flickering which extremley hurts my eyes.
I have already tried Ubuntu, OpenSuse, Fedora, Debian, FreeBSD. The problem is seen everywhere, only in Windows 7 everything works fine.
The flickering or flashing is like if one makes a vidoe capture of the monitor and watches the vidoe. I can clearly see the refreshing of the screen.

Currently I'm using Linux Mint 10. In the Monitor settings the system shows correct refresh rate, 60Hz .
I've also created an xorg.conf file and included a Modeline from Xorg.0.log(Modelines from EDID). But there is no improvement at all.
Are there any ideas how this problem can be solved? It is really disturbing, so that I cannot work more than 20 minutes using Ubuntu.
Thank you in advance.

Here is my xorg.conf:
