Public bug reported:

Hello guys.I am new in ubuntu and i bought a brand new laptop acer
aspire 5745-dg with windows but i put and ubuntu together.My problem is
that the brightness changes from windows but i cannot change it inside
ubuntu,for example the fn keys don't work and i cant change the
brightness from power management too.The funny part is that the fn keys
for the sound work great!My problem is that the brightness is always at
maximun as a result to reduce my battery life!!I have reported this
problem to many sites but noone could help me..:/I have already tried to
change some lines in grub but nothing changed.I also have heared that
this might be a bios problem...Can you please help me with this serious
problem???I would appriciate that!!!
