The mute sound function key is also ignored [Fn F8]. I can control volume with the mouse using pavucontrol or gkrellm-volume.No progress.
if the keys are recognized by the kernel, then you can remap them with an udev hwdb rule.
Test with evtest if the keys get a scancode and a keycode. Something like: type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e0 type 1 (EV_KEY), code 29 (KEY_LEFTCTRL), value 1 In this case I pressed the Left Ctrl key, which has a value of 700e0 Create a new rule in /etc/udev/hwdb.d with something like: evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pn* KEYBOARD_KEY_ed=volumeup KEYBOARD_KEY_ee=volumedown etc... use evemu-describe to find your evdev:... line also read: https://wiki.archlinux.org/index.php/Map_scancodes_to_keycodes https://wiki.archlinux.org/index.php/Extra_keyboard_keys /lib/udev/hwdb.d/60-keyboard.hwdb for more information and examples Floris
