Hello, I do not know where to ask this question, but I think that kernel developers could help me. I have notebook with one special button on keyboard which is designed for turning ambient light sensor on and off. By default pressing button do nothing (I can turn ambient light sensor on/off via sysfs platform wmi module). Button press is reported by kernel input device AT Translated Set 2 keyboard and reports it as button "touchpad off". Of course "touchpad off" is incorrect and I'd like to ask which kernel key or button from /usr/include/linux/input.h should be mapped for my ambient light sensor button? Is there already some? And what is strategy for allocating KEY_* and BTN_* numbers? I'd like to know this, so udev could have correct DMI keymap hooks and other userspace programs can understand ambient light sensor button correctly. -- Pali Rohár pali.rohar@xxxxxxxxx
