Device Settings

Device

With this combo box you can select the device you want to edit, the settings below will adjust to the selected device. The list shows all connected pointer devices.

Enable this device

Uncheck this option to turn a device off. If a device it disabled, it won't send any coordinate updates to the pointer. By default all (new) devices are enabled.

Right-handed and Left-handed

If you select Left-handed the primary and secondary buttons on the mouse will be reversed.

Reverse scroll direction

If this option is enabled, the scroll direction will be reversed (sometimes called “natural scrolling”).

Acceleration

The factor at which the pointer's speed will increase as the cursor is moved, when the device moves more than Sensitivity pixels in a short time.

Sensitivity

The number of pixels the pointer must move in a short time before it starts accelerating.

Currently only touchpads using the Synaptics driver are supported.

Disable touchpad while typing

Turn the touchpad off while typing to prevent accidental clicks. The settings daemon will start the following command in the background when enabled: syndaemon -i 2.0 -K -R.

Tap touchpad to click

When this option is selected, tapping the touchpad with your finger will preform the same action as clicking the primary mouse button. The device property Synaptics Tap Action will be set to 1 2 3 ….

To click, tap on the touchpad. To double-click, tap twice. To drag an item, double-tap but don't lift your finger after the second tap. Drag the item where you want it, then lift your finger to drop.

Scrolling

Disabled

Disable scrolling with the touchpad. This will unset both the device properties below.

Edge scrolling

When this is selected, dragging your finger up and down along the right side of your touchpad will scroll vertically. If you also select Enable horizontal scrolling, dragging your finger left and right along the bottom of your touchpad will scroll horizontally. This will set the device property Synaptics Edge Scrolling.

Two-finger scrolling

When this is selected, tapping and dragging with one finger will work as normal, but if you drag two fingers across any part of the touchpad, it will scroll instead. If you also select Enable horizontal scrolling, you can move your fingers left and right to scroll horizontally. Be careful to space your fingers a bit apart. If your fingers are too close together, they just look like one big finger to your touchpad. This will set the device property Synaptics Two-Finger Scrolling.

Enable horizontal scrolling

Allow scrolling horizontal. The way horizontal scrolling works depends on the Scrolling type you've selected.

Currently only devices using the Wacom driver are supported.

Tracking mode

Pen (absolute)

In absolute mode the active area of the tablet will be mapped to the screen. Every time you go down to the tablet at the same point with an absolute device the pointer will appear at the same point of the screen.

Mouse (relative)

In relative mode the tablet has the behavior of a mouse. This means, that if you take the pen off from the surface, move it and go down again, the pointer does (ideally) not move.

Rotation

None (right-handed)

The tablet is not rotated in software and uses its natural rotation.

Half (left-handed)

The tablet is rotated by 180 degrees (upside-down).

Clockwise

The tablet is rotated 90 degrees clockwise.

Counterclockwise

The tablet is rotated 90 degrees counter-clockwise.

Threshold

The number of pixels the pointer must move before a drag operation will start. Default value is 8 pixels.

Time

Two mouse clicks in less than this length of time (in milliseconds) will be considered a double click. Default value is 250 ms.

Distance

The mouse pointer cannot move farther than this distance between two clicks for them to be considered a double click. Default value is 4 pixels.
