Try adjusting it with the xrandr command.

First find your device name by entering:

xrandr

There's an output line like:

LVDS connected 1440x900+0+0 (normal left inverted right x axis y axis) 367mm x 230mm

The enter a command like (substituting for your device LVDS):

xrandr --output LVDS --prop --verbose --gamma 1.0:1.0:1.5

experiment with value, partitcularly the last, blue, value, until you like the results. The number must be floating point and they stand for red:green:blue.

The driver shouldn't matter.

See this man page.
