Public bug reported:

I've a netbook samsung n150 with ubuntu 12.04, yesterday when I've
upgraded from kernel version 3.2.0-33-52 to 3.2.0-34.53 immediately it
didn't work fn keys for brightness of monitor.....it didn't effect!!!
and also this kernel is very slow in perfomance than old kernel
3.2.0-33-52. in this moment i am using the previous kernel.

I wait from you that you'll improve this kernel because i've just read
other message about problems on the same kernel.

Wait your reply,

thanks,

carlo.
