### Example Commit Message

Source: https://github.com/linuxwacom/xf86-input-wacom/wiki/For-Developers:-Commit-Messages

Illustrates a well-formatted commit message with a clear summary, detailed explanation, and sign-off information. Follow this structure for clarity and context.

```text
HID: wacom: support named keys on older devices

Some Wacom devices have keys with predefined meanings. However, when
support was originally added for these devices, the codes for these
keys were not available yet. These keys were thus reported with
the numbered KEY_PROG* range.

Some missing key codes were added with commit 4eb220cb35a9 ("HID: 
wacom: generic: add 3 tablet touch keys") and we are now able to
report the proper key codes. We continue to report the original
KEY_PROG codes so as not to break any unknown applications that
may depend on them.

Also, to support the touch key, track its state in the pad report.

After attempting to set a VCP value, use `getvcp` to verify the change. This confirms the color preset was set to 5000K.

```bash
$ ddcutil --mfg=WAC --model=CintiqPro32PT --sn=7KQS0H1000016 getvcp 0x14
```

```bash
VCP code 0x14 (Select color preset           ): Setting: 5000 K (0x04)
```

After identifying a display, use the `capabilities` command along with display identifiers (manufacturer, model, serial number) to view its supported settings, such as luminosity, contrast, and color presets. This command provides a detailed list of VCP features and their possible values.

```bash
$ ddcutil --mfg=WAC --model=CintiqPro32PT --sn=7KQS0H1000016 capabilities

### Interrupt Process with SIGINT

Source: https://github.com/linuxwacom/xf86-input-wacom/wiki/Debugging

If the X server was started with 'run' in GDB, Ctrl+C might not work. In such cases, you can send a SIGINT signal to the process using the 'kill' command with its PID.

```bash
$> sudo kill -SIGNIT `pidof Xorg`
```

### Match Wacom or Waltop Devices by Product Name and Path

Source: https://github.com/linuxwacom/xf86-input-wacom/wiki/xorg.conf.d

This snippet applies to devices that have either 'Wacom' or 'Waltop' in their product name AND match the specified device path. Use this to target specific input devices for configuration.

```xorg.conf
Section "InputClass"
	# This is for human-readable purposes only.
	Identifier "Wacom class options"
        # Match all devices with either Wacom or Waltop in their product name
	MatchProduct "Wacom|Waltop"
        # AND match devices with a device path of /dev/input/eventX.
	MatchDevicePath "/dev/input/event*"
EndSection
```
