Another fix for brightness control issues Fedora 16

[jlturn]

Hey everyone, So I had been searching for a fix for an issue where the fn keys don't seem to increase or decrease the screen brightness on my Samsung laptop using fedora 16 64bit, and gnome.

I had followed a post found on the fedora forum where the problem was fixed by reinstalling bash. This did not seem to fix the problem for me. The solution I have tried that has worked so far is by adding:

acpi_backlight=vendor acpi_osi=Linux

to the end of the

GRUB_CMDLINE_LINUX

variable in

/etc/default/grub

and then running the following command to regenerate grub and restarting,

sudo grub2-mkconfig -o /boot/grub2/grub.cfg


I hope that this will work for others as well if resintalling bash does not solve the problem.

I did this, but after restarting the pc it doesn't boot anymore.

I'd got this message on boot: "Failed to start LSB: init script for TCSD" and so I disabled TCSD by doing "systemctl disable tcsd.service", but still it gets stuck at "Started WPA Supplicant daemon".
