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.

Exceeding the speed of light - possible or not

May or may not be possible. However, one thing is pretty clear from the space time diagrams is that the cause-effect relationship of things can be violated if this limit is exceeded.
