Is it possible to increase the brightness of laptop screen above what's possible in BIOS and Ubuntu Linux/Windows ?

I have an old laptop (Lenovo-X200s) and the maximum brightness is rather dark. I wish to increase it further beyond what's possible using normal available tools.

I don't care if an increase in brigthness will decrease the lifetime of the laptop, since I need it for most a year.

Can someone provide me with suggestions ?

In Linux:

xrandr --output DVI-0 (your output) --brightness 2 (or the value you want)

In Windows:

Calibrate your display color (Type "Calibrate display color" in the Windows searchbox)

    How do I see my outputs in Ubuntu ? And what is xrandr specifically ?

    To check the outputs, I think you just do "xrandr". xrandr is just a configuration utility.

    Thank you for the answer. It helps, but increasing brightness just to 1.02 makes gray more or less white.

    Try in less increments or search for using 'gamma' instead of brightness in xrandr.
