Using the Device

Multitouch & Gestures

Only some multitouch gestures are enabled on the Nexus 7. For the gestures that are not enabled, the failures are a combination of bugs and unimplemented code. Section 5 of the Unity Gesture UI Guidelines covers what behaviors the gestures are supposed to do. Right now, only the following gestures are known to work:

Gesture	Correct Behavior
Single finger tap	Select item
Single finger drag	Move item
Single finger double tap	Select a whole word or item
Single finger triple tap	Select a paragraph or related set of items
3 finger tap	Bring-up Unity grab handles
4 finger tap	Open the dash

Resetting the Device

If the device is locked-up then you can reset it by holding down Volume Down and Power. When the screen goes black release the buttons. If you end up in fastboot mode (by holding down too long) just click the power button and it will boot back into Ubuntu.

sudo password

The default sudo password is ubuntu.

Starting Onboard (onscreen keyboard) when it fails to auto-show

There is a known issue where onboard does not always show automatically when a text input field is selected. In these cases, onboard can be shown manually. To show onboard, first find the onboard indicator in the panel, (the icon should look like this: .

Click this indicator, which will then bring up the Onboard menu. From here, simply select "Show Onboard"

You might also want to enable Show floating icon when Onboard is hidden from the Onboard Preferences > General tab. With this setting enabled, when you hide the onboard onscreen keyboard, an icon displays. Click the icon to show the keyboard again. This may be easier than launching Onboard again from the Onboard indicator panel menu.

Increasing Font Size

You may want to increase the default font size. This not only makes GUI text easier to read, it also makes the menus easier to navigate because the selection targets become larger.

Open Settings from the Unity launcher panel.
Open the Universal Access settings app.
On the Seeing tab, set the Text size to Larger (this is the largest possible setting).

Attaching a USB Device to the Nexus 7

You can attach USB devices to the Nexus 7 if you purchase a Micro USB Host Cable (OTG Cable) from Amazon or other electronics retailers. The cable may be difficult to find at local stores and you may have to order online. Once this cable is attached to the Nexus 7 you can attach a USB hub or a USB device directly.

$Warning /!\$ There is no way to charge the device while it is connected to the OTG cable $Warning /!\$
