Hello Johannes, Johannes Stezenbach [2009-12-14 13:37 +0100]: > I don't understand. I only append to the force_release attribute > because the kernel already removes duplicates. Oh, indeed it does: $ cat /sys/devices/platform/i8042/serio0/force_release 133-139,143,147,369-370 $ echo '133-139,143,147,369-370,143,147,370,371,147,371' | sudo tee /sys/devices/platform/i8042/serio0/force_release $ cat /sys/devices/platform/i8042/serio0/force_release 133-139,143,147,369-371 So indeed we then don't need to worry about sending duplicate keys.

Hm, it seems to work just fine here: $ echo 133 | sudo tee /sys/devices/platform/i8042/serio0/force_release133 $ cat /sys/devices/platform/i8042/serio0/force_release 133 So it seems every time you write the file you have to do it completely (or read the original one). So I think your approach is fine after all, and we just need the other small cleanups.
