Hello, there is request to introduce some option (via sysfs) to disable one input device. Originally it was for tsc2005 touchscreen found on Nokia N900 cellphone. Use case is to completely disable touchscreen when phone is in pocket or when screen is locked via slide switch (to prevent random clicks).
But it would be better to have disable option for all input devices. Sometimes input device is not use and only consume power. Another case is when input device (e.g. keyboard or touchpad) is integrated into machine (e.g. on laptops) and user does not want to use it (so make sure that kernel does not send events to userspace). I would like to ask, how to solve it? What do you think about adding new sysfs file "disable" (accept values 1 or 0) for every input device? With "1" it cause that kernel will drop all events from specific input device and if driver provide some function is can be called (e.g. for power management or disabling device at hardware level). Or do you prefer something other? -- Pali Rohár [email protected]
