Gnome merges Global Shortcuts
This is a rough draft, and I'm looking for feedback on the high-level shape of it. Most important is that I added another type...
It wasn't clear for me what the hell is a "Global Shortcut" I heard the term first time in my life, I found the answer in the upstream PR:
It's designed so that applications can register actions that can be triggered globally (i.e. regarless of the system's state, like focus).
It's strange it wasn't possible until now, or the main thing it's now DE independent?
On Gnome I use Run or raise extension, and with this I can run or switch to running apps with global shortcuts, so this was definitely working from Gnome extensions.
Gnome Extensions run in the Gnome shell, so they have special privileges.
Wayland’s security focus prevents apps from listening in on all user key presses, which means they can’t know you used a keyboard shortcut unless the app is focused.
The Global Shortcut Portal was made to address this. An app registers for a global shortcut, and when the user activates the shortcut, the portal tells the app that it’s been activated.
Thanks for the context!
It's because this feature was implemented as a pseudo-keylogger on X11. All X clients could listen to the compositor state at all times (including input), even if input was focussed on another (potentially sensitive) application.
In Wayland, clients have almost zero knowledge of the compositor's state. This was an explicit design choice to enhance security and enable modular features via wayland protocols. Of course, this also killed every implementation of app-specific global shortcuts.
Wayland protocols take a lot of time to get agreed on - They need multiple implementations across different compositors (usually means KDE and GNOME need to implement the protocol spec and agree to it) and the specs can take a long time to design and reach production.
Obviously this does hurt uptake for Wayland since issues can take years to resolve, but the core team are very aware of the pitfalls of X11's development and have long preferred this slow and methodical approach in the hopes it's sustainable and maintainable into the future.
it's still up to individual apps to implement the portal I think
Does anyone know what the status on KDE implementing this is?
