Hardware

In the following sections you will find examples of how to configure some hardware aspects of your GNOME desktop, including keyboard or mouse preferences, handling of removable drives (and other media) or screen resolution.

Modifying Keyboard Preferences

To modify some keyboard settings (such as autorepeat preferences or typing break sessions) click Computer+Control Center+Hardware+Keyboard.

Keyboard Preferences Dialog

  1. On the Keyboard tab you can set some general keyboard preferences, such as enabling keyboard repeat with individual delay and speed options or enabling or disabling the blinking of the cursor and defining the speed. For more information about the individual options, click Help.

  2. To select your keyboard model click the Layouts tab and select your model from the Keyboard model list.

  3. To add a new language layout, click Add and choose a language layout to add to the list. You can select different layouts to suit different locales. Select one layout as Default.

  4. On the Typing Break tab you can set typing break preferences. For more information about the individual options click Help.

  5. If all options are set according to your wishes, click Close.

For configuration of keyboard accessibility options refer to the Section 4.2.1.5, “Configuring an Accessible Keyboard”.

Configuring the Mouse

To modify some mouse options click Computer+Control Panel+Hardware+Mouse to open the Mouse Preferences.

Mouse Preferences Dialog

  1. The General tab is divided into several sections. Use the radio buttons in the Mouse Orientation section to specify if the mouse buttons are configured for left-hand or right-hand use.

  2. Check the option in the Locate Pointer section on the General tab to enable a mouse pointer animation when you press and release Ctrl. This feature can help you locate the mouse pointer.

  3. Use the sliders in the Pointer Speed section on the General tab to define the Acceleration and Sensitivity of your mouse pointer.

  4. Use the slider in the Drag and Drop section on the General tab to modify the distance that you must move an item with the pointer before the action is interpreted as a drag and drop action.

  5. Use the slider in the Double-Click Timeout section on the General tab to define the maximum delay between the two clicks of a double-click. If the interval between two clicks is greater than the interval specified here, the action is interpreted as two separate clicks instead of a double-click. Use the light bulb icon to check double-click sensitivity: the light will light up briefly for a click, but stay lit for a double-click.

  6. If all options are set according to your wishes, click Close.

For configuration of mouse accessibility options refer to Section 4.2.1, “Configuring Mouse Behavior”.

Installing and Configuring Printers

The Printing module lets you connect to any available local or remote CUPS server and configure printers.

  1. To start the Printers module, click Computer+Control Center+Hardware+Printing.

  2. The CUPS server to which you are connected is shown in the status bar. To connect to a different CUPS server, click Server+Connect, enter URL of the CUPS server and press Connect. The printers available at the server are shown in the main window. Update the list of available printers with the Refresh button.

  3. To add a new printer press New in the toolbar and follow the configuration wizard.

  4. To configure printer properties, set it as the default printer or view its print queue, right-click the printer's icon and select appropriate option from the menu.

Configuring Screens

To specify the resolution, refresh rate and orientation for your screen or to configure multiple screens, click Computer+Control Center+Hardware+Screen Resolution and modify the options.

  2. To set options for any monitor, click on the monitor's icon in the blue preview area and set its Resolution, Refresh Rate, and Rotation (orientation) using the drop-down lists underneath.

  3. If you use multiple monitors, you can set their respective positions by dragging their icons in the blue preview area to the appropriate location. Alternatively, you can configure your monitors to show the same image by checking Mirror Screens.

  4. To show an applet icon in your system tray which enables you to rotate your screens, check Show Displays in Panel.

Configuring a Touchpad

Use the Touchpad module to configure the behavior of a touchpad. This module is only available on computers containing touchpads, such as laptops. In most cases the default behavior should remain unchanged. Click Computer+Control Center+Hardware+Touchpad to start the Touchpad module. This allows you to enable or disable the touchpad or to set its sensitivity, tapping and scrolling behaviour. This module also controls mouse-pointer acceleration.
