Hi, The battery triggers aren't working for some reason, trying to write them comes back with -EINVAL. I'm on somewhat old kernel, 3.17, but the relevant parts haven't changed from the commit Frank made in 2014 adding the MAC address to the name. # cat trigger none timer heartbeat backlight [default-on] sony_controller_battery_00:26:5c:31:a2:c8-charging-or-full sony_controller_battery_00:26:5c:31:a2:c8-charging sony_controller_battery_00:26:5c:31:a2:c8-full sony_controller_battery_00:26:5c:31:a2:c8-charging-blink-full-solid # echo sony_controller_battery_00:26:5c:31:a2:c8-charging-blink-full-solid > trigger bash: echo: write error: Invalid argument The shorter triggers do work. Is it something caused by the long name, or the colons? Do they work for others?
