3) The sound volume up/down function keys [Fn up/down arrow] no longer
respond (xfce4). However the screen brightness keys function normally
[Fn left/right arrow]. 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
