Large print in Wayland

Wayland is a newer replacement for X11. In Wayland, a lot depends on the “compositor” component. These notes are for the *Wayfire* compositor, as shipped with the Raspberry Pi Desktop OS based on Debian 12 in 2023.

Screen magnification

• Hold down the ‘Super” key (the one with the commercial logo on it, called the “start” key in Windows) while scrolling with the mouse wheel.
• This gives full-screen GPU-driven magnification with panning, but it blurs and it doesn’t wait for the mouse to hit an edge before panning, so it doesn’t feel as stable as old X11 hardware zoom. Also the mouse pointer does not enlarge. We hope they’ll add more options for this in future.

Permanent desktop scaling

• The desktop, including the mouse pointer, can be scaled up without blur by editing ~/.config/wayfire.ini and adding a line like scale = 1.5 to an [output] section (e.g. [output:HDMI]—just create a section called [output] if none are there).
• As the resulting desktop is not scrollable and it limits what can be shown on screen, you might want to use just a moderate scale factor here and make up for the rest by setting larger fonts in applications. You can then maximise windows and use Alt-Tab to switch between them.
• A bug in at least some versions of Wayfire results in the scale being lost whenever you open any Preferences dialogue (such as to set keyboard layout) and you have to restart the session to get it back.
