Launchpad Entry: wacom-tablets-ui
Contributors: Alberto Milone
Currently there's no easy way for users to enable, configure and calibrate Wacom Tablets and Tablet PCs as they have to do it manually in the xorg.conf. For this reason we should develop a simple graphical interface which can write user settings to the xorg.conf and which allows testing of the stylus, eraser and buttons inside a drawable area.
Ubuntu now provides a simple graphical interface to enable and calibrate computer drawing tablets.
* Claire plugs in her USB tablet but HAL detects only the stylus
* Mark wants to configure the sensitivity of his tablet
* John wants to use the touch capability of his tablet PC
* Gwen wants to constrain the movement of her stylus to her first screen
- hardware profiles for different models
- custom profile:
- users are asked a few questions on the characteristics of their tablet/tablet PC
- buttons on the tablet, touchscreen, (serial or USB) connection, etc.
- the different components (stylus, eraser, pad, touch) can be configured separately
- some components are not available in certain hardware configurations
- some options are not available in certain components
- Mode (Screen, Window → Relative/Absolute)
- Pressure Sensitivity
- Click Threshold (or Button Threshold)
- Allow cursor to move across multiple screens (for screens with different resolutions)
- Rotation (?)
- a drawing area to test the pressure sensitivity of stylus and eraser devices
- applies/saves settings (2 alternatives):
- settings are applied and saved only after clicking on the “Apply” button
- settings are applied immediately but are saved only after clicking on the “Save” button
- makes the wizard show up when no relevant device is found in the xorg.conf
- allows users to change the tablet model (maybe with a button to run the wizard again)
- displays a dialog to warn the user that s/he has to restart X with the tablet plugged in in order to use it (when the tablet is already configured in the xorg.conf)
- The first supported frontend will rely upon GTK.
A drawing area (using Cairo and GooCanvas for the GTK UI) for testing
