Changing Native LVDS Contrast on Thinkpads
XVideo Contrast
The xvattr program can be used to change the contrast of videos being played with programs like wxvlc and mplayer.
Native LVDS Contrast on Radeon
On many thinkpad models, the LVDS panel contrast cannot be changed using standard tools. In Microsoft Windows, this is done with the proprietary ATI configuration program. However, neither fglrx nor the radeon driver can do this.
