# Hardware Setup

## Card Reader

 `With a card inside a card reader` 
```
# echo 1 > /sys/bus/pci/rescan

```

The command isn't 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](/index.php/PulseAudio "PulseAudio") and [pulseaudio-ctl](https://aur.archlinux.org/packages/pulseaudio-ctl/):

```
   "/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

```
