Pixel tips

Last week. Simon Long from Raspberry Pi released a new version of Raspbian with several new features. The most visible of these is the new-look desktop skin, named PIXEL (Pi Improved Xwindows Environment, Lightweight).

PIXEL splash screen

PIXEL splash screen

There’s a lot of user interface (UI) tweaks both functional and visual…

  • new splash screen on boot
  • stunning background images added
  • a whole new set of icons
  • larger ‘drag handles’ for resizing windows (that’s bugged me for years)
  • windows now have rounded corners
  • new font rendering package for better typography

I think the new look is a big improvement and I love it. ‘Grabbing’ the corner of a window to resize it has always been a bit harder than it should have been, so I’m delighted about the larger drag handles too.

So What Else is New?

Other tweaks include using Chromium as default browser and realvnc is pre-installed. I’m delighted by the addition of Chromium as it means I can use a Pi3B for G+ hangouts which I use a lot when I should be working for communicating and collaborating with people. I can now do this in the workshop whilst monitoring twitter and QC testing Pro Hats – all using the same Pi3.

I Want to Tweak PIXEL

But we all like to personalise our computing, so what if you want to tweak it for yourself? How would you manage that? Below are a few tips I’ve collected showing ways you can tweak or customise your PIXEL/Raspbian.

Don’t Want a Splash Screen?

If you prefer the retro look of the boot messages racing by, rather than the splash screen, there are two ways to achieve this…

  1. Using raspi-config application, choose “boot to CLI” instead of “boot to desktop”
  2. Opening raspi-config

    Opening raspi-config

    Select "To CLI"

    Select “To CLI”

    If you boot to CLI (command line interface) and then want the desktop, you’ll need to type startx to run it.

  3. Delete “quiet splash” from /boot/cmdline.txt
  4. sudo nano /boot/cmdline.txt
    remove quiet splash

    Removing "quiet splash" disables splash screen

    Removing “quiet splash” disables splash screen

    Save and exit (CTRL+X, y, ENTER)

Want to Change the Splash Graphic?

This is quite easy. All you have to do is replace /usr/share/plymouth/themes/pix/splash.png with your chosen graphic. It must be called splash.png though.

Supposing your required splash graphic is /home/pi/raspitv.png you would move (mv) it like this…

First let’s back up the old one in case we want to revert…
sudo cp /usr/share/plymouth/themes/pix/splash.png /usr/share/plymouth/themes/pix/oldsplash.png

Then move the new graphic…
sudo mv /home/pi/raspitv.png /usr/share/plymouth/themes/pix/splash.png

sudo is required because the target directory is owned by the root user.

So then the default splash becomes your own customised version…

NOTE: If you do a dist-upgrade your splash file will be overwritten with the new official PIXEL one showing the new version.

How to Disable Tooltips

If you hover over objects in the user interface, you see pop-out bubbles (‘callouts’) explaining what they are/do.

Here's a tooltip (callout)

If you no longer wish to see these, or find they get in your way, you can switch them off by adding a new line…

gtk-enable-tooltips = 0

…right at the beginning of the file ~/.themes/PiX/gtk-2.0/gtkrc

nano ~/.themes/PiX/gtk-2.0/gtkrc
gtk-enable-tooltips = 0

Then next time you restart LXDE the tooltips should be disabled.

I Miss the Raspberry Pi Desktop Logo. Can I Reinstate it?

Yes. You can select it with the Appearance Settings application – it lives here…

Then be sure to change “fill screen with image” to “centre image on screen” or the Pi logo will be huge.

Where are the New Icons Stored?

  1. Nice post, i thought of changing the splash screen and after reading this i did. Easy to do when you know where to look :D

  2. great tips, nice desk,,wonder whats behind the paper towel you don’t want people to see,,,lol

    • Those two squares of paper towel are covering two 12V halogen lamps which illuminate my face when I’m shooting videos. The light is a bit harsh without a diffuser, so I have a piece of paper towel on each acting as diffuser. So probably not as exciting as you imagined it might be. :)

  3. Thanks for all this new info, Alex, very useful.

    I’m glad to see another “cluttered” work area, like my own, but am hard pressed to understand how you will incorporate the deer horn into a future project.
