Components

As previously mentioned, Regolith is a collection of existing open source components that are integrated into a desktop environment. Due to standards regarding the way UI components should communicate and years of integration between components, for the most part is simple to swap out parts of the UI for others.

The following table lists each UI component and notes regarding it’s mutability:

UI Component	Purpose	Alternatives	Swappable
XOrg	Display System	Unknown	Unknown
i3-gaps	Window Manager	i3-wm, others	Difficult but possible
i3bar	Desktop Bar	Polybar, lemonbar, others	Yes, by changing the i3 config file.
i3xrocks	Status Indicator Manager	i3blocks, barista, others	Yes, by changing the i3 config file.
Rofication	Desktop Notification Manager	Dunst, gnome-flashback	Yes, by changing the i3 config file to load the Notification backend and Rofi UI, and configuring i3xrocks to load the blocklet.
Remontoire	Keybinding Viewer	Conky	Yes, by changing the i3 config file to load a different help program.
gdm3	Login Manager	lightdm, sddm, xdm, others	This is configured in Ubuntu. Installing an alternative session manager should present a prompt to specify which to use.
gnome-flashback	Desktop Environment	None	No

Due to the breadth of the topic, more details are not available here. Experimenting with different UI components is a fun way to learn more about the internals of the operating system. It is recommended to first experiment in a VM running Regolith to avoid breaking your working environment.
