Nosotros've been able to set up the background paradigm for users for quite some time. Did yous know you can also control the epitome of the background wallpaper for the sign on screen too?

Here'due south the different options for setting up a wallpaper epitome and how to configure each in the Google Admin Console.

Chromebook Background Image

Regardless of what programme you lot utilize to create your Chromebook background image, there are a few things to go along in heed.

The paradigm you upload to the Google Admin Console has to be a JPG file. Almost any prototype program will permit you to save your image in this format.
All devices in an OU will apply the same image for the sign on screen. You'll need your Chromebooks moved into sub OUs if you want different images for different groups of Chromebooks. For example: Cart A, Cart B, 3rd Grade, etc…
About Chromebooks have an eleven″ screen with a resolution of 1330 10 768. I recommend you make your image that size. It is piece of cake to resize an image with programs such as Pigment on a Windows PC. If you lot don't size the epitome appropriately, the paradigm volition automatically be cropped to fit.

Chromebook sign on screen background image

A sign on screen wallpaper is a neat way to differentiate Chromebooks when no one is logged on. For example, you lot could have one cart of Chromebooks have a bright green groundwork, while another cart has a bright yellow image. This mode if a Chromebook gets moved to the wrong cart it would be hands identified.

There are also several ways to change the concrete advent of your 1:ane Chromebooks which I discussed in my Ways to Customize Your Personal or School Chromebook post.

The wallpaper for the sign on screen is a device setting. The wallpaper is just shown when a user is non logged on. Once a user logs on, the user's wallpaper will be shown. We'll talk about user wallpaper setting in another section below.

I don't want to go also far down a rabbit hole, but keep in mind that it is non possible to have a specific background when users are logged onto specific Chromebooks. For example, yous can't take only the library Chromebooks have a certain groundwork when users are logged onto them. This is because the background for a logged in user is a user setting, not a device setting.

Image and text placement

If I was to push out my example images above, I would quickly observe an effect when looking at a Chromebook. The sign on screen would look like this.

The login box shows up in the middle of the screen. I tin can't run into the words "Cart A" and my Schooled in Tech logo is partially covered up. Instead of putting your images and text in the centre, I recommend moving them to the left side instead. This mode the sign in box will not cover anything upwards and neither will the listing of existing profiles that shows upwardly on the right side of the screen.

Deploy a Chromebook sign-on screen background

The background for the Chromebook before a user logs on is set in the Devices settings in the Google Admin Console. If you do non take admin rights in your domain, your tech department should exist able to brand these changes for you.

Specifically in Device Management > Chrome Direction > Device Settings

The same image is applied to all of the Chromebooks in an OU. So if you lot want different images for different carts, each cart would need its own OU.

Whenever yous are making changes in the Google Admin Console, brand sure yous have selected the correct OU

Scroll down and click onUPLOAD WALLPAPER FILE

Another practiced use instance for a sign on background is your default enrollment OU. That manner you tin can piece of cake tell when a Chromebook has non been motion to its correct OU.

How to force the aforementioned groundwork for Students Using Chromebooks

But like with the device background, a user background volition exist applied to all users in an OU and inheriting sub OUs.

The placement of images and text are not as of import on a user background. I would even so make sure to size the paradigm from the correct resolution. Again for an eleven″ Chromebook, the image resolution should be 1330 x 768.

The user background volition merely show up when a window is not maximized. So if you accept a item web folio gear up to launch every fourth dimension users logon on, yous may never see the groundwork unless the user closes or minimizes Chrome.

Though it might be seldom seen, pushing out a background ensures that a user doesn't fix an inappropriate background.

User backgrounds are deployed using the Google Admin Console past browsing toDevice Management > Chrome Direction > User Settings

Scroll downward and click onUPLOAD WALLPAPER FILE

Then choose the file you desire to upload

Finally, click theSave push.

You can employ the aforementioned epitome for your device background and your user groundwork, just you would still need to upload the image in both Google Console setting areas.

By default, when you open aNew Tab in Google it shows the Google Search page.

In the lesser right corner of the screen you'll encounter an option to customize this screen.

When you click on the pencil / Customize, you accept the choice to change theChrome background.

Unfortunately, at this time, there is not a way to disable this option in the Google Admin Console. A feature asking has been submitted to Google, but there is no ETA on when (or if) Goggle volition provide an option to block irresolute the background of the Google Search page.
