NAMEwdaemon − Wacom tablet hotplugging emulator

SYNOPSISwdaemon [options]

DESCRIPTIONwdaemon is an application to abstract Wacom tablet hotplugging​. wdaemon creates virtual input devices using the uinput kernel module and makes them available while at run time keeps looking for specified devices to be plugged in​. Instead of looking for the actual device, the X server is configured to look for the emulated device​. wdaemon will provide the an identical device description, allowing the server to initialize properly​. Once the physical device is plugged in, wdaemon will forward all events through the emulated device and thus to the X server​. For easier recognition, the device name is prefixed with the string "wdaemon"​. This can be disabled at configure time​.

OPTIONS−h Print a help message −p Path to the device file to monitor, load to or extract −t Device type, use −w to get a list −c file Use <file> as configuration file​. −d N Enable debug messages up to level N −o file Redirect debug messages to file −f Fork on start and enter in daemon mode −w Get a list of supported devices and their numbers −a Autoconfigure, generate a configuration file based on currently plugged in tablets −l file Load a device description from file −x file Extract a device description into file −s Use syslog for debug messages (conflicts with −o) −v Print version number

CONFIGURATIONwdaemon requires configuration in the udev(7) system setup, the xorg​.conf(5) configuration files and finally wdaemon itself​.

UDEV CONFIGURATIONwdaemon requires a tablet to have a predictable unique device file​. This is usually accomplished through udev rules​. For example, on modern systems, a tablet may appear as /dev/input/by−id/usb−Tablet_PTZ−630−event−mousewhich will point to the event device of a Intuos3 6x8​. The wdaemon package provides udev rules to create symlinks to known tablet models in the form of /dev/input/wacomX, /dev/input/wacom−tablets/wacom−<model>−tabletX and /dev/input/wacom−tablets/wacom−<model>−tablet−<phys path>The last link provides unique type per USB port​. Once a tablet reliably appears at a given device path, wdaemon may be configured to use it​. The second step consists in creating a persistent name for uinput devices created by wdaemon, so you can configure your xorg​.conf right​. An example udev rule to do this: KERNEL="event*", PROGRAM="/lib/udev/wdaemon_is_uinput​.sh", \ RESULT="056a−0000", \ SYMLINK="input/uinput−devices/uinput−wacom−penpartner−tablet%e"This will create a symbolic link for penpartner tablets​. Notice it needs wdaemon_is_uinput​.sh script (included in this package)​. Also included in this package, 11−uinput−wacom​.rules has these rules done for most tablets​. With the rule in place, a wdaemon−created device will have predictable device files​. This makes xorg​.conf configuration simpler​.

XORG​.CONF CONFIGURATIONThe X server should be configured to use the devices by wdaemon instead of the actual physical devices​. An xorg​.conf(5) section may look like this: Section "InputDevice" Identifier "cursor" Driver "wacom" Option "Type" "cursor" Option "Device" "/dev/input/uinput−devices/uinput−wacom−intuos3−6x8−tablet" Option "Mode" "relative" Option "Tilt" "on" Option "Threshold" "20" Option "Suppress" "6" Option "USB" "On" EndSectionNote that if the X server is configured to hotplug devices, it must ignore physical devices in use by wdaemon​. Example xorg​.conf​.d(5) and fdi files are provided with this package​.

WDAEMON CONFIGURATIONNow wdaemon must be configured to monitor the physical tablet and create matching uinput device​. A /etc/wdaemon​.conf for two devices may look like this: device = 36,/dev/input/wacom−tablets/intuos3−6x8−tablet device = 6,/dev/input/wacom−tablets/graphire4−4x5−tabletNotice the spaces​. The wdaemon parser is very rudimentary at this point and can get easily confused​. The device types 36 and 6 can be determined by running wdaemon −wWhen wdaemon is started, it will create devices of the types specified in the wdaemon​.conf configuration file and monitor the device path​. Whenever the physical tablet appears, wdaemon will forward events from the device to the uinput device​. If the device type is unknown to wdaemon, see SAVING AND LOADING DEVICES below​.

AUTO−CONFIGURATIONThe −a option was added in 0​.14 to generate a wdaemon​.conf based on the currently plugged−in tablets​. First, plug in all tablets that should be emulated by wdaemon in the future​. Then run wdaemon −aThis command prints a configuration file that can then be used for wdaemon​. Auto−configuration only works with device types known to wdaemon​.

SAVING AND LOADING DEVICESwdaemon has the device descriptions for a number of devices built−in​. For devices that are unknown to wdaemon the device description must be gathered from the physical device and loaded on startup​. A device description may be extracted with the −x option: wdaemon −p /dev/input/by−id/usb−Tablet_PTZ−630−event−mouse −x Intuos3_6x8​.descThe resulting device file is a description of the device currently available as /dev/input/event12​. The description may be loaded again with the −l option: wdaemon −p /dev/input/by−id/usb−Tablet_PTZ−630−event−mouse −l Intuos3_6x8​.descwdaemon will initialize a device based on the description file and forward events from the specified device path​.

CONFIGURATION FILE FORMATThe configuration format supports the following keywords: debug = <debuglevel>Where debuglevel is an integer equal or larger than 0​. device = <type>,<path>Where type is an integer representing the device type and path the path to the device to monitor​. description = <desc>,<path>Where desc is the path to a device file description and path the path to the device to monitor​. wdaemons parser is simple and the spaces in the configuration file must be exactly as above​. That is, no space at the beginning of the line, a space before and after the = sign and no spaces elsewhere​.

ENVIRONMENT VARIABLESUINPUT_DEVICE Specifies the path to the uinput kernel device​.
