To solve this, click the icon at the very right of the menu bar and go to <gui>System Settings</gui>. In the Hardware section, choose <gui>Displays</gui>. Try some of the <gui>Resolution</gui> options and set the one that makes the screen look better.

If a wireless device is <em>not</em> listed, the next steps you take will depend on the type of device that you use. Refer to the section below that is relevant to the type of wireless adapter that your computer has (<link xref="#pci">internal PCI</link>, <link xref="#usb">USB</link>, or <link xref="#pcmcia">PCMCIA</link>).

Other users can't edit the network connections

If the network menu has disappeared from the menu bar, your <app>Network Manager</app> may not be running. To start it up again:

If other users really need to be able to change the connection themselves, make it so the connection is <em>not</em> set to be available to everyone on the computer. This way, everyone will be able to manage their own connection settings rather than relying on one set of shared, system-wide settings for the connection.

Create a wireless hotspot

If your network doesn't automatically assign network settings to your computer, you may have to manually enter the settings yourself. This topic assumes that you already know the correct settings to use. If not, you may need to ask your network administrator or look at the settings of your router or network switch.

If your touchpad supports multi-finger taps, <link xref="mouse-middleclick">middle-click</link> by tapping with three fingers at once.

A <em>web proxy</em> filters websites that you look at, it receipts requests from your web browser to fetches the web pages and their elements, and following a policy will decide to pass them you back.

To double-click, tap twice.

Select the network connection that you want to set up manually. For example, if you plug in to the network with a cable, look at the <gui>Wired</gui> tab.

Many mice and some touchpads have a middle mouse button. On a mouse with a scroll wheel, you can usually press directly down on the scroll wheel to middle-click. If you don't have a middle mouse button, you can press the left and right mouse buttons at the same time to middle-click. If you find you are unable to middle-click this way you can try following <link href="https://wiki.ubuntu.com/X/Quirks#A2-button_Mice"> these instructions</link>.

On scrollbars and sliders, a regular click in the empty space moves by a set amount (such as one page) in the direction you clicked. You can also middle-click in the empty space to move to exactly the location you clicked.

Set an image, color, or gradient as your desktop background.

If there is no entry that has the name of the mouse followed by <sys>[XExtensionPointer]</sys>, then the mouse was not recognized by your computer.

Make sure the mouse is turned on. There is often a switch on the bottom of the mouse to turn the mouse off completely, so you can move it from place to place without it constantly waking up.

Click a button and see if the mouse pointer moves now. Some wireless mice go to sleep to save power, so might not respond until you click a button. See <link xref="mouse-wakeup"/>.

You can click, double-click, drag, and scroll using only your touchpad, without separate hardware buttons.

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.

If your touchpad supports multi-finger taps, right-click by tapping with two fingers at once. Otherwise, you still need to use hardware buttons to right-click. See <link xref="a11y-right-click"/> for a method of right-clicking without a second mouse button.

When tapping or dragging with multiple fingers, make sure your fingers are spread far enough apart. If your fingers are too close, your computer may think they're a single finger.

If network settings don't get assigned automatically, you may have to enter them yourself.

Click <gui>Save</gui>. If you are not connected to the network, click the network icon on the menu bar and connect. Test the network settings by trying to visit a website or look at shared files on the network, for example.
