Good day everyone!
Why does sometimes after I turned my laptop on it doesn't change the backlight of
my LCD when I pressed the decreased backlight button (fn + left).
My laptop is an acer aspire 5315 and sometimes it works and
sometimes not. I am a little bit annoyed because I always wanted
to lower or adjust my LCD's backlight to have a longer battery life.
I have also tried using the xbacklight -set command and just like
the problem above it sometimes work and sometimes not.
I think the problem is not in my videocard because I configured
slackware and it detected it w/ intel 960 GMA (X3100).
Why is that when I try to adjust my LCD's backlight it happens
to be a hit or miss??
Anyone w/ the same problem??
thanks in advance!!
