You can set a wallpaper on both the home screen and lock screen of a supervised iOS device. As mentioned, the device will need to be supervised. Supervision can be implemented via Apple’s Device Enrollment Program (DEP for short), but DEP will require MDM to implement supervision, and with a device enrolled and supervised via MDM, you’ll need to use the MDM to set the wallpaper. You can also use Apple Configurator 2. To use Apple Configurator 2 to set a wallpaper on a supervised iPhone or iPad, first save the image or images lo call on an iOS device. Once saved to the Apple Configurator machine, open Apple Configurator 2 and plug a device in. Then right-click on the device, choose the Modify menu and then Wallpapers… from the Modify menu. When prompted, use the Choose image… button to set the Lock Screen (the screen that is displayed when the device is locked) and the Home Screen (the background behind all your icons on each screen of the iPhone or iPad). Once you have chosen the appropriate images, click on the Apply button. You can also set lock screen text from Apple Configurator 2. To do so, use the “Custom Text…” button at the bottom of the screen and enter the text you’d like the lock screen to display when waking a device up (before you enter the passcode on the device). Then click on the Apply button. The device will install the new wallpaper (note that devices will need to be plugged in and have be unlocked to install these new options). Now the home screen should use the new image as should the lock screen.
A really neat new feature in 2012R2 is that Hyper-V can resize a running virtual machine (.vhdx) to the smallest possible size, while the virtual machine is running. To do so, use Get-VM in PowerShell. Here, we’ll use the -Path option to define the location of our vhdx, the -ToMinimumSize option to indicate that we’d like to shrink it down as low as we can go and -AsJob so it runs in the background:
Resize-VHD –Path D:\myVM.vhdx –ToMinimumSize -AsJob
The article I did a few weeks ago on customizing the Mac OS X Server Wiki banner seems to have been a little incomplete. I discussed customizing the banner for a full web browser. However, the banner looks differently when viewed from an iPhone. I’ve had a couple of questions about how to customize the banner for iPhone so I figured I’d finish what I started. As I mentioned in the last article, you can simply customize (or replace) the banner-bg.png file located in the /usr/share/collaboration/css/serverhome_static/img directory. This will alter the appearance when viewed from a full web browser. You can also simply edit the following files (same directory) to further alter the appearance (including those for iOS):
- footer-bg.png – The Apple logo on the initial splash page.
- iphone-banner-bg.png – The banner file to customize for when users are accessing the splash page from iPhone rather than the browser (what this article was originally about). As with the last article, here’s a sample ArtText document for customizing the banner.
- iphone-footer-bg.png – The footer image from iPhone.
- iphone-service-button.png – The background for services from iPhone (tip: make sure to leave something in place of the little blue arrows so people know to click on these).
- iphone-service-icons.png – Smaller version of the service-icons.png, without reflection (Note: you may have seen clips of these in presentations I have done).
- more-bg.png – The arrow beside the View All per service on the opening page.
- service-bg.png – The background for the various services you have enabled on the initial landing page.
- service-icons.png – collection of the service icons that indicate what an item is. These include the icon for blog, wiki, mail, change password, Podcast Producer and iCal. While these may seem generic I have to give the designers who made them credit as I have yet to make anything approaching the quality of these so I almost invariably leave them as-is.
In Mac OS X you can set your screen saver as your background image. To do so, run the following command:
Once you close Terminal or hit Control-C then you will set the background back to what your initial background was. Hope you enjoy!/System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background
DeployStudio has a very nice background image that it uses by default for the NetBoot set. But you can customize the image that’s used if you wish to have something more, well, customized. Simply mount the DeployStudioRuntime sparseimage file from the DeployStudioRuntime nbi file that was created when you elected to generate the NetBoot set. You can do so by simply opening the nib file and then double-clicking on the sparse image. From here, browse into the System and then the Library and then the CoreServices directory in the NetBoot set. From here find the DefaultDesktop.jpg file. Replacing that file will replace the background that is used when you boot to the NetBoot set. The higher resolution the better!
OK, OK, you’re right – if I’m going to cover customizing the loginwindow of Mac OS X then the least I can do is cover Windows as well. Because the registry is basically a bigger, more monolithic version of the defaults domains, we’re going to do pretty much the same stuff at the login screen for Windows. First, open the registry editor (regedit) and browse to HKEY USERS .DEFAULTControl PanelDesktop
Then edit the value for wallpaper, typing in the path to the image you’d like to use. To set it as tiled add TileWallPaper and set it to the integer 1 or to stretch add WallPaperStyle and set it to the integer 2.
The acceptable use hint at the login screen is a little different. Open the policy editor (Control Panel, System & Maintenance, Administrative Tools, Local Security Policy). Open up your Local Policies and click on Security Options. Then find Interactive Logon: Message Text For Users Attempting To Log On and right-click on it, choosing Properties from the contextual menu. Then enter the message you want displayed and click on the OK button.
You can also edit the title bar of that box (although that seems a little extra much) using the Interactive Logon: Message Title For Users Attempting To Log On similarly.
Alternatively (if you’re looking at a one-off customization) you can use Logon Studio from StarDock and do all of this from a GUI.
