[ltp] Re: tpacpi bug in tpacpi::thinklight/brightness for X1 Carbon

[flip]

Hi,

I have the same problem on W530 which has backlight keyboard and thinklight.
Pressing Fn+Space toggles between 4 different states: keyboard with low
brightness, high brightness, thinklight (without keyboard backlight), and
off.
I tried to do what you wrote with input-events:

root@flipc /home/flip # input-events 5
/dev/input/event5
   bustype : BUS_HOST
   vendor  : 0x17aa
   product : 0x5054
   version : 16641
   name    : "ThinkPad Extra Buttons"
   phys    : "thinkpad_acpi/input0"
   bits ev : EV_SYN EV_KEY EV_MSC EV_SW

I hope this helps in any way.
