Fedora 18 Brightness Control Acer Aspire E1-571

Hello all,

I have recently bought an Acer E1-571 aspire laptop and have installed fedora on a partition and the brightness controls in Fedora aren't working (with the screen being stuck on maximum brightness).

I've looked up other solutions online and most suggest changing the grub file (almost all of the solutions I have found have also been for older versions of Fedora). I have changed the grub file to read:

GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/swap rd.md=0 rd.dm=0 $([ -x /usr/sbin/rhcr\
ashkernel-param ] && /usr/sbin/rhcrashkernel-param || rd.luks=0 vconsole.key\
map=us rd.lvm.lv=fedora/root rhgb quiet acpi_osi=Linux acpi_backlight=vendor"

Then after that copying the new config to grub2 and rebooting but still no brightness control.

Any help would be much appreciated!
