Increasing display brightness of Samsung NC10 Ubuntu

Display brightness can be easily controlled by using the setpci command. The setpci command basically controls the display device whose address can be found using the lspci command. In case of the NC10 the command looks like:

sudo setpci -s 00:02.1 f4.b=FF

In this case, 00:02.1 is the address of the Intel display adapter, and we further set brightness to maximum value by using FF. Minimum value is 00. Hence the range is all intermediate values from 00 to FF. f4 is the address of the register, and the .b possibly signifies a byte.
