[Pkg-acpi-devel] Bug#708444: thinkpad x121e brightness control with F8, F9 does not work anymore

[albatros69 at gmail.com]

Hello,

On a fresh jessie install (beg. of June), I've been bitten by the exact 
same issue. Brightness control was working with Fn+F8/F9. But it stops 
suddenly to work without any obvious reason, except the regular upgrades.

Echoing a value in /sys/class/backlight/acpi_video0/brightness is still 
functional though.

Regards,
