DVD support cannot be provided by default in Ubuntu due to legal and technical restrictions. Most commercial DVDs are encrypted and so require the use of decryption software in order to play them.

Use Fluendo to legally play DVDs

You can buy a commercial DVD decoder that can handle copy protection from <link href="apt:fluendo-dvd">Fluendo</link>. It works with Linux and should be legal to use in all countries.

Use alternative decryption software

In some countries, the use of the below unlicensed decryption software is not permitted by law. Verify that you are within your rights to use it.

Check that they have the right video codecs installed.

Other people can't play the videos I made

If you made a video on your Linux computer and sent it to someone using Windows or Mac OS, you may find that they have problems playing the video.

To be able to play your video, the person you sent it to must have the right <em>codecs</em> installed. A codec is a little piece of software that knows how to take the video and display it on the screen. There are lots of different video formats and each requires a different codec to play it back. You can check which format your video is by doing:

Right-click on video file and select <gui>Properties</gui>.

Go to the <gui>Audio/Video</gui> tab and look at which <gui>codec</gui> is listed under <gui>Video</gui>.

Ask the person having problems with playback if they have the right codec installed. They may find it helpful to search the web for the name of the codec plus the name of their video playback application. For example, if your video uses the <em>Theora</em> format and you have a friend using Windows Media Player to try and watch it, search for "theora windows media player". You will often be able to download the right codec for free if it's not installed.

There are a few other problems which might prevent someone from playing your video. The video could have been damaged when you sent it to them (sometimes big files aren't copied across perfectly), they could have problems with their video playback application, or the video may not have been created properly (there could have been some errors when you saved the video).

Use the tablet left-handed

Some tablets have hardware buttons on one side. The tablet can be rotated 180 degrees to position these buttons for left-handed people. To switch the orientation to left-handed:

Open <gui>Wacom Graphics Tablet</gui>.

If no tablet is detected, you'll be asked to <gui>Please plug in or turn on your Wacom tablet</gui>.

Switch <gui>Left-Handed Orientation</gui> to <gui>ON</gui>.

Switch the tablet between tablet mode and mouse mode.

Set the Wacom tablet's tracking mode

<gui>Tracking Mode</gui> determines how the pointer is mapped to the screen.

Next to <gui>Tracking Mode</gui>, select <gui>Tablet (absolute)</gui> or <gui>Touchpad (relative)</gui>.

In <em>absolute</em> mode, each point on the tablet maps to a point on the screen. The top left corner of the screen, for instance, always corresponds to the same point on the tablet.

In <em>relative</em> mode, if you lift the pointer off the tablet and put it down in a different position, the cursor on the screen doesn't move. This is the way a mouse operates, allowing you to cover distances on the screen with less hand movement.

Map the Wacom tablet to a specific monitor.

Choose a monitor

Click <gui>Map to Monitor…</gui>

Check <gui>Map to single monitor</gui>.

Next to <gui>Output</gui>, select the monitor you wish to receive input from your graphics tablet.

Only the monitors that are configured will be selectable.

Adjust the settings of your Wacom tablet.

Wacom Graphics Tablet

Define the button functions and pressure feel of the Wacom stylus.

Configure the stylus

The lower part of the panel contains details and settings specific to your stylus, with the device name (the stylus class) and diagram to the left. These settings can be adjusted:

<gui>Eraser Pressure Feel:</gui> use the slider to adjust the "feel" (how physical pressure is translated to digital values) between <gui>Soft</gui> and <gui>Firm</gui>.

<gui>Button/Scroll Wheel</gui> configuration (these change to reflect the stylus). Click the menu next to each label to select one of these functions: No Action, Left Mouse Button Click, Middle Mouse Button Click, Right Mouse Button Click, Scroll Up, Scroll Down, Scroll Left, Scroll Right, Back, Forward.

<gui>Tip Pressure Feel:</gui> use the slider to adjust the "feel" between <gui>Soft</gui> and <gui>Firm</gui>.

If you have more than one stylus, when the additional stylus gets close to the tablet, a pager will be displayed next to the stylus device name. Use the pager to choose which stylus to configured.

What is the "Super" key?

This key can usually be found on the bottom-left of your keyboard, next to the <key>Alt</key> key, and usually has a window/squares icon on it. It is sometimes called the Windows key, logo key, or system key.

If you have an Apple keyboard, there will not be a Windows key on your keyboard. The <key>⌘</key> (Command) key can be used instead.

The Super key serves a special function in <em>Unity</em>. If you press the Super key, the Dash is displayed. If you press <em>and hold</em> the Super key, an overlay showing many of Unity's keyboard shortcuts appears until you release the Super key.

The Super key can help you do even more than that, though. To learn about more uses for the <em>Super</em> key, see the <link xref="shell-keyboard-shortcuts">keyboard shortcuts</link> page.
