           Summary: Setting brightness doesn't work out of the box on Acer
                    Extensa 5235

I use this laptop since 2010 and I always have to write something into
/etc/default/grub, to make the bríghtness changeable.
Now on Ubuntu 12.04 it is properly working if I write "acpi_backlight=vendor"
to this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
I tried the latest upstream kernel, but this bug is still exist in it.
Is it possible to fix this bug, to make the brightness change working out of
the box?
I hope I attached everything which necessary, if not please let me know what I
should send.
