ATI Contrast Control - Open Source ATI Driver

Using the open source xf86-video-ati driver, is there an easy way to change the screen contrast?

I recently switched from Ubuntu to Arch. On Ubuntu I had used the ATI proprietary driver "Catalyst". The default settings for the computer were really a strain on the eyes. However, using the Catalyst GUI to change the brightness and contrast I could get it to a nice setting. I would much prefer an open source driver to a proprietary one and even the Arch Wiki states that support for the proprietary driver has been dropped due to "dissatisfaction with the quality and speed of development". I can resort to this driver if I need to, but I'd rather not.

I've been able to get some level of brightness control by changing the /sys/class/backlight/acpi_video0/brightness, but this only gives me so much control because the value goes from 0 to 8. However, this would probably be acceptable if I could also find a way to control the contrast of the screen. Using this driver is there anyway to easily do this?

Thank you for your time!

Not exactly the answer to your question, but you could try xgamma or redshift.

Edit: Ah... I'm guessing you're using a laptop.
