brightness

We have a desktop system running Ubuntu 8.04.4, and it is connected to a standard desktop LCD monitor. Unfortunately, in 8.04.4, the brightness of the image is cranked way up. It appears to be a graphics driver issue. Unfortunately, installing a newer GPU driver for this Intel GPU is very difficult to do. So, I am looking for a software (or config file?) solution to achieve this.

Note: Ubuntu 9.10 and higher do not exhibit this issue, so this is not a hardware problem. Note: VNC-ing to this machine from another does not exhibit this issue either.

Also, I installed "DisplayCalibrator.app", and it does not work very well (the app comes up, but the contents of the window are blank).

Is there anything that I can add to the xorg.conf file to correct this issue?

Also, this solution: http://superuser.com/questions/96539/adjust-contrast-and-brightness-in-ubuntu did not resove my issue.

Thank you all for the help!
