monitor brightness issue

I'm running GNOME on Debian Sid. I usually turn off my monitor on night and when I go to school and leave computer on to do some long processes. The problem is that when after few hours I turn monitor on again - screen is very bright and smooth. To make it look ok again I have to do off->on procedure again (sometimes twice) which can of course damage the monitor. I'm sure that this is not a hardware problem, becouse on winxp it's fine. I tried screensavers and "Saving power" options (I'm not sure if this is right english name) but it doesn't seem to change anything. Do you have any ideas what I can do?

#dpkg-reconfigure xserver-xfree86

make sure you got the correct information for your video card, monitor's horizontal and vertical frequencies, depth color.

Maybe playing with the Contrast and Brightness configurations in your monitor with the control buttons.

Monitor's horizontal and vertical frequencies are surely ok - I checked it at producer's web site for exactly my monitor model. My video card is Radeon 9600 XT - I installed the fglrx driver and used the fglrxconfig, so I didn't messed with the XF86Config-4 file directly (I'm not sure if options available in this configurator can cause the problem). The color depth is set to 24bit.

I'm a bit afraid to reconfigure the xfree, since now it works for 2d and 3d modes - and life teached me that messing with working fglrx can only make the things worse. I hope simple backup of the XF86Config-4 file will be enough...

I'm also having a brightness issue, though it's not quite the same as yours. I'm running Gnome on sarge distro and I have my ATI drivers working (finally) so I'd really prefer not doing anything that could screw it up. My monitor brightness level is fine until I play Enemy Territory, and then its wayyyyy too dark. I went to the configuration utility in ET and turned the brightness all the way up, and set brightness to max on my monitor and it looks like it does next to nothing.

I have found a temporary (and interesting) fix though. I start up Wesnoth, go to configurations, turn gamma waaayyy up and exit. (My desktop is really really bright after that). Then I go to ET and the brightness config util looks like it should and the game plays great. I don't recall any sort of brightness/gamma configuration utility in gnome. Am I missing something here?
