Bye Raspbian! Long Live Raspberry Pi OS!

Last week, we reported a “new” Raspberry Pi 4 SBC with 8GB RAM launched last week, together with a beta version of “Raspbian” 64-bit needed to make full use of the extra RAM, although the 32-bit version can also address the full 8GB thanks to LPAE, but with a limitation of 3GB per process.

It turns out the launch of the new board, effectively killed Raspbian. But by name only, as the recommended Raspberry Pi operating system is now called Raspberry Pi OS with three 32-bit images namely Desktop with recommended apps such as Wolfgram and Mathematica, Desktop, and Lite for headless applications, as well as the Raspberry Pi OS 64-bit beta that’s yet to be officially released, but can be downloaded from the forums and works on Raspberry Pi 3 and 4 boards.

Raspberry Pi OS Magnifier

Apart from the name change, and support for 64-bit kernel and rootfs, the Raspberry Pi Foundation also introduced a few other software changes in the first version of Raspberry Pi OS include a magnifier (mage), Bookshelf program for easy access to free Raspberry Pi magazines such as The MagPi, HackSpace magazine, and Wireframe, as well as some books.

Note that if your language is not English, there’s a bug with Bookshelf (“disk full”), and you may need to run “sudo apt update” followed by “sudo apt upgrade” before running the program.

The magnifier had to be written from scratch because existing Debian magnifier applications did not work quite the same way the magnifiers in MacOS and Ubuntu do. The magnifier can be enabled from the taskbar or by pressing Ctrl-Alt-M. It will automatically follow the cursor or focus button in applications that support the accessibility toolkit. Chromium is one of the program that does not support it yet, so you’d have to use Firefox instead:

Note that contrary to Chromium, Firefox does not support hardware video decoding.

There’s also an optional “User research” where users can fill a questionnaire about their use case(s) for Raspberry Pi board(s), as well as various bug fixes and tweaks including ALSA now treating HDMI socket and the headphone jack as separate audio devices. If you’re using the Raspberry Pi OS Lite or prefer to work from the command line, simply create the file .asoundrc in your home directory:

Where x should be 0 for HDMI or 1 for the headphone jack. If the file is missing HDMI will be used by default.

You can also install the magnifier and bookshelf in your existing Raspbian installation as follows:
