After upgrading to Ubuntu 14.10 brightness control no longer works on Lenovo Thinkpad X220. Fn+Home/Fn+End doesn't work, the only way is to echo value to:
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight/brightness
I use Awesome WM, but it doesn't seem to be related to Awesome. |
