Exhibition: Change background in Time (Homebrew) [webOS 2.1+]

Although webOS will allow you to toggle an image on/off for the Time screen in Exhibition Mode, there is no option to adjust that image. However, just as you can use a homebrew solution to change your boot screen animation images, you can apply the same methods to change your exhibition background. The default image that is provided is found at /usr/palm/sysmgr/images/dockmode/clock-wallpaper.png and is a 480x480 .PNG image. However, while the image is a square, your screen isn't. Anchoring on the top-left corner of the screen, webOS will zoom in/out the image to first fit the height of your screen, and if there is any empty space along with sides of the picture, it will then zoom in to fill up the width.

So, to change the background, you need to find a PNG image to use. If you have an image but it's in a JPG or other non-PNG format, you can always load that pic up in the Photos and take a screenshot to "convert" it to a PNG image. Once you have the file, just rename it to clock-wallpaper.png, copy it /usr/palm/sysmgr/images/dockmode/ directory on your device, and reboot your device. Continue reading after the break if you need step-by-step directions.

There are 2 relatively easy methods to do this using either Internalz Pro (on-device solution) or webOS Quick Install (using a PC)

Using Internalz Pro

  1. If you do not already have the images on your PC, connect your device to the computer and put it in USB mode, copy the .png files to your phone (remember where you put them), and then properly eject the phone from USB mode
  2. On your device, open Internalz Pro
  3. Swipe down from the top-left corner to bring down the Internalz Pro Application dropdown menu and select "Preferences"
  4. Scroll to the bottom of Preferences and turn "Master mode" on, and select "YES" to the warning prompt.
  5. Back-swipe to return to Internalz Pro
  6. Navigate to the folder on your device where you put the png file. Note that the main USB drive is /media/internal/, so if you put the files in an "exhibition" folder in the USB drive, you will want to navigate to /media/internal/exhibition /
  7. Tap on the clock-wallpaper.png file and select "Copy"
  8. Find and select /usr/palm/sysmgr/images/dockmode/ then tap "Select"
  9. Access the Internalz Pro preferences again and turn off Master Mode
  10. After he next time you reboot your device, the exhibition time background will be changed

Using webOS Quick Install

  1. Put your phone in Developer Mode by typing "upupdowndownleftrightleftrightbastart" without the quotes (or "webos20090606" for the less adventurous) and selecting the "DeveloperMode" app.
  2. Switch Developer Mode to ON.
  3. Connect your device to the computer and select "Just Charge"
  4. Open webOS Quick Install on your PC
  5. Select "Tools" then "Send File"
  6. Press the "..." button and find clock-wallpaper.png file on your computer
  7. For "Destination Folder" put in "/usr/palm/sysmgr/images/dockmode"
  8. Press "Send to Device"
  9. Follow the directions above to access Developer Mode, but this time turn it off.
  10. After the next time you reboot your device, the exhibition time background will be changed
