If you have multiple displays and they are not mirrored, you can have different settings on each display. Select a display in the preview area.

On some laptops, you can physically rotate the screen in many directions. It is useful to be able to change the display rotation. You can choose the rotation you want for your display from the <gui>Rotation</gui> drop-down list.

Open <gui>Mouse &amp; Touchpad</gui>.

In the <gui>Touchpad</gui> section, check <gui>Disable while typing</gui>.

The <gui>Touchpad</gui> section only appears if your system has a touchpad.

Under <gui>General</gui>, adjust the <gui>Double-click</gui> slider to a value you find comfortable.

Click the <gui>Test Your Settings</gui> button to test. A single click in the window will highlight the outer circle. A double-click will highlight the inside circle.

In the <gui>General</gui> section, switch <gui>Primary button</gui> to <gui>Right</gui>.

You can quickly open a new window for an application with middle-click. Simply middle-click on the application's icon, either in the <gui>Launcher</gui> on the left, or in the <gui>Dash</gui>.

If your pointer moves too fast or slow when you move your mouse or use your touchpad, you can adjust the pointer speed for these devices.

Adjust the <gui>Pointer Speed</gui> slider until the pointer motion is comfortable for you.

You can set the pointer speed differently for your mouse and touchpad. Sometimes the most comfortable settings for one type of device aren't the most comfortable for another. Just set the sliders on both the <gui>Mouse</gui> and <gui>Touchpad</gui> sections.

Click, drag, or scroll using taps and gestures on your touchpad.

Click, drag, or scroll with the touchpad

In the <gui>Touchpad</gui> section, check <gui>Tap to click</gui>.

Two finger scroll

You can scroll using your touchpad using two fingers.

In the <gui>Touchpad</gui> section, check <gui>Two finger scroll</gui>.

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 <gui>Enable horizontal scrolling</gui>, 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.

Content sticks to fingers

You can drag content as if sliding a physical piece of paper using the touchpad.

In the <gui>Touchpad</gui> section, check <gui>Content sticks to fingers</gui>.

This feature is also known as <em>Natural Scrolling</em> or <em>Reverse Scrolling</em>.

Mouse reacts with delay before it starts working

Wireless and optical mice, as well as touchpads on laptops, may need to "wake up" before they start working. They automatically go to sleep when not in use to save battery power. To wake up your mouse or touchpad, you can click on a mouse button or wiggle the mouse.

Laptop touchpads sometimes react with delay after you stop typing before they start working. This is to prevent you from accidentally touching the touchpad with your palm while typing. See <link xref="mouse-disabletouchpad"/> for details.

When you plug an iPod into your computer, it will appear in your music player application and also in the file manager (the <app>Files</app> application in the <gui>Launcher</gui>). You must copy songs onto the iPod using the music player - if you copy them across using the file manager, it won't work because the songs won't be put into the right location. iPods have a special location for storing songs that music player applications know how to get to but the file manager does not.

A further reason why songs might not be appearing on your iPod is that the music player application you're using does not support converting the songs from one audio format to another. If you copy a song which is saved in an audio format that is not supported by your iPod (for example, an Ogg Vorbis (.oga) file), the music player will try to convert it to a format that the iPod does understand, such as MP3. If the appropriate conversion software (also called a codec or encoder) is not installed, the music player will not be able to do the conversion and so will not copy the song. Look in the software installer for an appropriate codec.
