This document provides a reference for the snap interfaces available for Ubuntu Frame.
The current snap interface connections can be checked by issuing:
$ snap connections ubuntu-frame

The above is the default set of connections upon installation. It serves the default use case of Frame running as a system service. You can change the connections through a gadget snap or manually:
sudo snap connect ubuntu-frame:login-session-control
The wayland connection will be automatic if Frame is the only provider of the slot. On Classic systems this slot is provided by snapd, so upon installing a snap that has a plugs: [wayland], a manual connection (to any wayland slot). The same applies if you have multiple snaps that have slots: [wayland] installed on a Core system:
sudo snap connect <snap>:wayland
# or, on Core
sudo snap connect <snap>:wayland <compositor>:wayland
The interface connections serve the following purposes:
| Interface | Purpose | Notes |
|---|---|---|
| ubuntu-frame-diagnostic | The diagnostic screen feature | |
| graphics-core22 | GPU userspace drivers | |
| hardware-observe | Avoiding excessive logging from libinput | |
| login-session-control | Running as an unprivileged user | Not auto-connected, as the primary way to run Frame is as a system service |
| network-bind | Operate as a X11 server | |
| opengl | Access the GPU for hardware acceleration | |
| wayland | Act as a Wayland compositor | |
| x11 | Run nested on a X11 session |
