Installing LibreOffice on the Raspberry Pi?

LibreOffice is a free and open source office suite that includes applications for word processing, spreadsheets, presentations, and more. It is a great option for Raspberry Pi users who want an office suite on their device. Installing LibreOffice on the Raspberry Pi does take some work, but it can be optimized to run faster and more efficiently with a few key steps.

Installing LibreOffice on the Raspberry Pi?

Downloading LibreOffice

The first step is to download the latest armhf version of LibreOffice from the official website. This is the version optimized to run on ARM-based devices like the Raspberry Pi. The download is around 200 MB, which while large for the Pi, is needed for all the applications.

When the download finishes, extract the archive file to a location like /home/pi/libreoffice to install it.

Optimizing Memory Split

By default, the Raspberry Pi only allocates 128 MB of memory to the GPU. This leaves more for the CPU, but can slow graphics performance.

To optimize LibreOffice, adjust the memory split to allocate more memory for graphics processes:

  1. Open the Raspberry Pi Configuration tool
  2. Go to the “Performance” tab
  3. Set the GPU memory to 256 MB for best LibreOffice performance

This memory boost will allow LibreOffice to run faster and process complex documents more smoothly.

Adding Font Packages

LibreOffice may show text formatting oddly or use fallback fonts without extra font packages installed.

Run this command to install free font packages:

sudo apt install fonts-liberation libreoffice-l10n-en-za mythes-en-us

  • fonts-liberation adds new fonts like Liberation Sans
  • libreoffice-l10n adds grammar and spellcheck dictionaries
  • mythes enhances the built-in spellchecker

Now text should render properly in LibreOffice with better accuracy.

Using a Lighter Desktop Environment

The default Raspberry Pi OS desktop environment is quite heavy. Alternative “lite” environments like LXDE or Xfce use less RAM and CPU power.

Switching the Pi to boot to a lighter desktop can provide extra resources for LibreOffice:

sudo raspi-config

Under “System Options” choose the lighter desktop, like LXDE. Reboot for this to take effect.

Disabling Unneeded Services

Some default services and background processes that start with the Pi OS are unnecessary and waste resources if LibreOffice is the main application being used.

Try disabling some services that are not critical:

sudo systemctl disable rpcbind

sudo systemctl disable avahi-daemon

Reboot once again for maximum free memory for LibreOffice. Check with free -mh before and after to compare.

Adding Swap File for Extra RAM

With all optimizations so far LibreOffice should run faster. However, working with complex documents can still be slow on the Pi. A swap file essentially uses a bit of storage space as extra “virtual” RAM.

Here is how to create a 512 MB swap file:

sudo fallocate -l 512M /swapfile

sudo chmod 600 /swapfile  

sudo mkswap /swapfile

sudo swapon /swapfile

The extra memory allocation from disk will allow bigger files with graphics and tables to be edited more smoothly.

Key Takeaways

A few key ways to optimize LibreOffice performance on the Raspberry Pi include:

  • Allocating more GPU memory
  • Installing extra font packages
  • Using a lighter desktop environment
  • Disabling unneeded services
  • Adding a swap file for extra RAM

With these optimizations LibreOffice runs faster, launches quicker, and operates more efficiently even editing complex documents on the Pi. Carefully managing available memory is critical.

Conclusion

While the Raspberry Pi is not the most powerful device for running office software, LibreOffice can work well with careful configuration. The open source nature makes it accessible for all Pi users. Optimizing GPU allocation, adding fonts and dictionaries, using lighter environments, disabling services, and supplementing with swap space allows LibreOffice to run quite smoothly. With a few easy optimizations, the versatile LibreOffice suite can tackle documents of all kinds even on the Raspberry Pi.
