Firstly thank you for your efforts,
I actually got my N150 brightness keys working for the 1st time today thanks to you.
All I needed was the easy-slow-down-manager and backlight and the brightness keys worked !
That worked without the need to install the updated kernel packages.
How is it possible to only update the 2 packages but ignore the rest after enabling the PPA?
Speficially I want to ignore the kernel packages if possible,
I have tried apt-pinning but that didn't seem to work (possibly due to bad syntax..)
Can anyone help/give an example of working apt pinning?
