Hardware Setup

Card Reader

With a card inside a card reader: 

# echo 1 > /sys/bus/pci/rescan

The command is not needed until the next start of the machine.

Special Touch Keys

Only two keys can be remaped to use on DE, second and trird touch keys.

Touchkeys Scancodes: 

0xDB # First touch key, Dell apparently uses a key sequence here where 0xDB is a modifer, 0x2D stands for the touch key and 0x19 for the monitor toggle
0x85 # Second touch key
0x84 # Third touch key

One method to remap it is as systemd service: 

/etc/systemd/system/multi-user.target.wants/setsecondkey.service
[Unit]
Description=Setkeycode Second Key

[Service]
Type=oneshot
ExecStart=/usr/bin/setkeycodes 0x85 202

[Install]
WantedBy=multi-user.target

Tips and Tricks

XBindKeys

Volume keys configuration with PulseAudio and pulseaudio-ctlAUR: 

   "/usr/bin/pulseaudio-ctl down"
   m:0x10 + c:122
   Mod2 + XF86AudioLowerVolume

   "/usr/bin/pulseaudio-ctl up"
   m:0x0 + c:123
   XF86AudioRaiseVolume

   "/usr/bin/pulseaudio-ctl mute"
   m:0x0 + c:121
   XF86AudioMute
