Title:
8086:0be1 [HP Mini 110-4100] Backlight brightness control keys not
working
Status in Linux:
Expired
Status in linux package in Ubuntu:
Invalid
Bug description:
Problem: Function keys don't control de backlight brightness and can't
be controled by System Configuration either.
With stock Ubutnu distribution (both kernel and Xorg server) I get
this:
No entries in /sys/class/backlight whit or withtout
"acpi_backlight=vendor" grub line
Low level setpci command works
$ sudo setpci -s "00:02.0" F4.B="XX"
Where "XX" is anything between 00 and FF
On dmesg when pressing keyboard funciton keys:
Fn+F3 (Bright UP)

on isa0060/serio0).
