Re: Last update to 3.2.1-1 & kmod broke backlite brightness keys @ Samsung

Are you guys able to adjust the brightness by directly writing the brightness level into sys?

I used to do that with the command

 echo "15" > /sys/class/backlight/acpi_video0/brightness

However, regardless what value I choose, the brightness doesn't change at all.

In this case upgrading to udev-git doesn't solve my problem.

Regards

Mine has changed to /sys/class/backlight/toshiba/
and echoing no longer lowers it, so my acpi script fails on that part, but the fn keys work still? I have tried sending variables to all the files in there relating to brightness and one (actual_brightness) is not writable even tried changing permission to writable and still did not work. At least the fn keys still work for me.

I have an x505-887 toshiba just for reference.

udev 179-1 fixed this problem for me.
