Step-by-Step Guide: Enabling via System Settings
Linux Mint ships with a fully-functional on-screen keyboard accessible via System Settings in just a few clicks.
First, launch System Settings from the start menu or Application Menu under "All Applications":
Next, navigate to the Accessibility configuration section:
Here, scroll to the Keyboard settings pane and toggle the switch to enable the integrated on-screen keyboard:
Immediately upon toggling, the on-screen keyboard loads ready for input into any text field. Its default transparent theme floats neatly atop other applications:
But customizing the size, theme, layout and more personalizes the experience further. These areas for adjustment are just a tap away within the Keyboard settings:
Essential features are now activated, but onboard offers enhanced functionality for power users.
Step-by-Step Guide: Enabling Onboard
While Mint delivers out-of-box accessibility, the open source Onboard keyboard ups the ante for customization. Offering multi-touch support plus additional options, onboard is available via simple command line installation:
sudo apt install onboardWith software acquired, launch onboard to instantly access the expanded keyboard:
onboardOn first run, an introductory overlay highlights onboard‘s capabilities versus the stock keyboard:
These include:
🗹 Multi-touch features on compatible trackpads
🗹 One-handed modes
🗹 Word suggestions
🗹 Text prediction appropriate to writing style and language
🗹 User-trained word prediction
🗹 Customizable activities/application profiles
🗹 Universal access integration
Navigating onboard as a new user is intuitive – simply click keys as you would on a physical keyboard to type. But clicking isn‘t the only onboard input method…
Input Methods
Users can additionally leverage:
Scanning Selection – For users unable to physically press keys, scanning highlights each key, typing upon selection.
Dwell Clicking – Hover with mouse pointer triggers key entry after user-configured delay.
Head Tracking – Camera tracks head movements, using facial direction shifts to seamlessly indicate desired keys.
External Switches – Alternative mechanical buttons provide input where motion limitations necessitate.
Customizing onboard to suit personal needs and environmental constraints gives users independence tailoring the on-screen experience to their abilities.
Accessibility Advances
In a survey by the Linux Foundation of desktop Linux users with disabilities:
- 88% agreed that adaptive technologies provide essential accessibility
- 76% believe availability of these technologies has improved over past 2 years
Quoting Austin Hicks, Director of Digital Infrastructure at the Linux Foundation:
"It‘s important we continuously improve information technology accessibility so everyone can realize the benefits of open source software. Enabling rapid prototyping of new user interfaces tailored to underserved groups‘ needs exemplifies the open source ethos of empowerment through technology."
Hicks adds the onboard project welcomes new contributors and feedback from users with accessibility priorities. Truly embracing open source values means perpetually advancing universal access.
Customizing Your Onboard Experience
Beyond input methods, personalize the onboard interface design itself including:
Size – Scale onboard up to fullscreen or down to palm-sized
Opacity – Adjust keyboard transparency so it blends into your workflow
Theme – Choose compact dark or high contrast large print motifs
Sounds – Enable audio key presses for enhanced feedback
Dictation – Utilize speech-to-text capabilities built into onboard
Typed Word Prediction – Complete common phrases mid-type as onboard guesses desired text
Plus configure app-specific layouts, exportability, and more via Onboard‘s advanced settings dashboard:
The open community supporting onboard responds rapidly to user feature requests – if you dream it, onboard can build it!
Using Onboard Efficiently
Once comfortably accustomed, employing time-saving efficiency tips will optimize onboard productivity:
- Use text prediction accept keys
Ctrl + Shift + KP_Enterto rapidly insert suggested words - Create custom abbreviations that expand into phrases
- Train word predictions on vocabulary/names specific to your work
- Define hotkey shortcuts to swiftly evoke onboard when needed
- Program dwelling click delays to match typing cadence
Onboard offers functionality rivalling dedicated speech recognition and typing assistance software costing hundreds annually. Yet the freedom of this open platform comes gratis.
Troubleshooting Common On-Screen Keyboard Issues
If experiencing difficulty enabling or utilizing onboard, first validate if the following apply:
- Onboard package properly installed
- Latest onboard version from apt repositories
- Accessibility permissions enabled for onboard in System Settings
- Any custom scripts/shortcuts referencing correct binary paths
- X Windows/display server properly recognizing USB/Bluetooth
in the case of alternative input mechanisms
Additionally, ensure no resource constraints impeding performance:
- Sufficient free RAM to support keyboard rendering
- No interfering accessibility services creating conflict
Seeking further help from the active onboard community matrix yields friendly experts familiar with diagnosing new user issues. The collective goodwill helping tweak environments to onboard compatibility inspires.
Controlling Onboard from Terminal Scripts
Launching onboard from command line scripts facilitates incorporation into existing workflows. Basic examples launching the software:
onboard --showForce a specific theme variation without customization window:
onboard --theme=HighContrastScript defined hotkeys toggling visibility:
onboard --toggle-showingReview full documentation guiding advanced script usage.
On-Screen Keyboard Architecture on Linux
Under the hood, onboard interfaces with various frameworks to relay user input:
This allows transmitting key signals while overlaying the graphical keyboard interface atop X Windows driven applications. Analogous architectures enable equivant functionality on Wayland, Mir and alternative Linux display servers.
Development of the underlying evdev keyboard device driver within the Linux kernel itself enabled early forms of virtual keyboards. Today, this driver detects input from diverse assistive devices that map to standard keyboard events like key presses.
Interpreting signals from unfamiliar assistive peripherals into familiar keyboard input exonerated the need to write specialized applications with niche device support. Instead, applications simply react to synthesized key events as any physical keyboard.
This abstraction empowers Linux to incorporate new forms of input faster than proprietary operating systems; significantly advancing universal access.
