This page is about Dell XPS l702x hardware configuration.

## 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 third 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
