Fedora: want to map my Fn key to work on LXDE environment.

The Fn key is the wakeup key when the machine is suspended.
If anyone wants to map it to other functions, then that's okay.
I want to map the Fn key on Fedora 33 LXDE.
My keyboard hardware come with an Fn key , see:

These are the infos about my Linux and hardware:

Code:

$xmodmap -pke | grep "=$"
keycode   8 =
keycode  93 =
keycode  97 =
keycode 103 =
keycode 120 =
keycode 132 =
keycode 149 =
keycode 154 =
keycode 168 =
keycode 178 =
keycode 183 =
keycode 184 =
keycode 197 =
keycode 202 =
keycode 217 =
keycode 219 =
keycode 222 =
keycode 230 =
keycode 247 =
keycode 248 =
keycode 249 =
keycode 250 =
keycode 252 =
keycode 253 =

The Fn key is disable because I don't have a response from xev command:

Code:

$ xev

The GRUB starts with:

Code:

$ cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora-swap rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet splash acpi_osi=Linux selinux=1 enforcing=1
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

On most keyboards Fn does not produce a scan code of its own and therefore cannot be mapped. If xev and showkey don't detect it, you are out of luck.
