Scale apps to fit with screen

For apps that aren't supported for mobile (e.g. gnome-system-monitor, gnome-maps,...), it's possible to make Phoc to scale the app to fit with the display.

Per-app settings

As of phoc-0.4.0-2, scale-to-fit helper script is available, which makes this task simpler, and it's also very easy to adapt it to an app.

To do this, open the terminal:

1. Run your favorite wayland app, but with the following environment variable: WAYLAND_DEBUG=client
2. Look for something that looks like this [email protected]_app_id(“firefox”)
3. Now the name inside set_app_id is your appid (which is "firefox"), now to adapt it you need to exit the app and run: scale-to-fit firefox on

And without reboot or any modification, the application will start just fine.

If you don't want to hunt for one line in a lot of debug output, try using this script:

#!/bin/bash
WAYLAND_DEBUG=1 $1 |& grep 'xdg_toplevel@[0-9]\+\.set_app_id'

Just copy these two lines into a text file, e.g. named get-app-id.sh, on your PinePhone and make it executable by running $ chmod +x get-app-id.sh.

Let's say, you want to use KeePassXC, which does not scale well by default, but becomes somewhat usable by running scale-to-fit. But you won’t get there by running $ scale-to-fit keepassxc on. You can now run $ ./get-app-id.sh keepassxc and KeePassXC will start up. Go back to your terminal and you will find a line of text similar to:

[4049990.198] -> [email protected]_app_id("org.keepassxc.KeePassXC")

The part between the “” is what you are looking for. Just run $ scale-to-fit org.keepassxc.KeePassXC on and the next time you start KeePassXC, it should be usable.

Global settings

You can tell Phoc to scale every app that doesn't fit the screen. Tested with 0.5.1-1.
