Based on your preferred installation method, follow one of the following two sections to install Regolith. Unlike previous versions of Regolith, PPA and ISO installs result in different configurations. The PPA install favors coexistence with the existing Ubuntu desktop, while the ISO release optimizes for less resource utilization. Specifically, the ISO install is roughly 1Gb smaller and cold start RAM usage is reduced by about 200Mb as compared to the PPA installation.
Option 1: Regolith Linux via Installer
At this time an installer for Regolith 1.5 is not available, however the 1.4.1 installer can be upgraded to 1.5.1.
- Download an ISO image of Regolith R1.4.1 and then use an OS installation tool such as USB Creator to write the downloaded file into a USB device. Here are Ubuntu guides for performing this action in Windows, Mac, and Ubuntu.
- Reboot the computer and select the USB flash drive to boot from.
- Install or run the live environment by providing information when prompted during the setup process. See this tutorial to learn more about the installation process.
- When prompted, reboot the computer and login to your new Regolith environment!
The system will automatically upgrade to Regolith 1.5.1 with the following commands:
$ sudo apt update && sudo apt dist-upgrade
Option 2: Regolith Desktop via Repository (PPA)
- Add the Regolith release PPA to your system: (See below about PPA sources for other package archives.)
$ sudo add-apt-repository ppa:regolith-linux/release
- Install the Regolith desktop package (see below for other desktop packages available):
$ sudo apt install regolith-desktop-standard # or regolith-desktop-mobile for laptops
- Reboot the computer, and when logging in select the “Regolith” session from the gear menu (⚙️):
From this point, please proceed to the next section, configuration to learn about the most common changes people like to make to Regolith.
Status indicators missing after Upgrade
Regolith 1.4 changes the way in which blocks are installed and configured. This change is necessary to cleanly support the
arm64 architecture and make it simple to swap out components like the notification subsystem. From 1.4 onward, blocks are installed by the package manager. See this Howto on adding and configuring blocks.
In the case that the Regolith desktop environment becomes corrupted or otherwise unbootable, follow these steps to reset it. No user files will be removed as part of this process:
- Login to the stock Ubuntu session. If this session is not available, install it with
sudo apt install ubuntu-session. If you are unable to login, type ctrl alt F2 to access a TTY console. After installing the
ubuntu-sessionpackage you will have the option to select the “Ubuntu” session type in the login screen.
- Uninstall Regolith from within the Ubuntu session:
$ sudo apt purge regolith-* $ sudo apt autoremove -y $ rm -Rf ~/.config/regolith/flags
- Verify that no regolith packages are still installed with
apt list --installed | grep -i regolith. The command should not return any packages. If it does, manually uninstall them with
sudo apt purge <package>.
- Reinstall Regolith:
$ sudo apt install regolith-desktop i3xrocks-net-traffic i3xrocks-cpu-usage i3xrocks-time #also consider i3xrocks-battery i3xrocks-memory i3xrocks-weather
- Reboot the computer and when logging in select the “Regolith” session in the gear menu. At this point you can remove
ubuntu-sessionif you don’t want the stock GNOME session (optional).
Simply follow these steps to remove Regolith Desktop installed via PPA from your system:
- Log out of the Regolith session and into the default Ubuntu session.
- Open a terminal and run:
$ sudo apt purge regolith-desktop && sudo apt autoremove
- Now remove the PPA:
$ sudo add-apt-repository --remove ppa:regolith-linux/release
- You can now safely delete the directory
There are 4 sources for Regolith packages. The
release PPA is recommended for most users, but another may be better for you based on your needs. Here is a description of each PPA.
Starting with Regolith 1.5, there are a few different desktop packages that users can choose from to get specific package selections for their system and use case.
|Legacy package, no status indicators. Not recommended for new users.|
|A reasonable set of default packages for desktop users.|
|The bare minimum package set for power users. Not recommended.|
|Some additional packages on top of standard for laptop users.|
|Includes all of the official looks and status indicators available.|
Regolith packages are built for
armhf architectures. A stand-alone installer is not available for ARM-based systems such as the Rasberry Pi, however Regolith can be installed via PPA into any existing Ubuntu system running on the supported architectures. See above about installing Regolith via PPA.
