Bug ID: 97333
Summary: Missing feature for remote desktop and virtual machine
software: keyboard grabbing
Product: Wayland
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: wayland
Assignee: [email protected]
Reporter: [email protected]
One main difference between x11 and wayland is that in x11 all applications
receive all input whereas in wayland the compositor receives input and decides
which application may receive it. This causes a major issue with application
which need to grab keyboard input for running or showing a nested desktop. This
affects e.g. GUI virtual machines (SPICE clients), RDP clients, VNC clients,
nested kwin/gnome-shell/whatever. Without giving these wayland clients the
ability to grab input, they will not be able to handle keys which are also
global key bindings in your wayland compositor, e.g. Alt+Tab or the Super key.
Games might also be affected, I don't know that for sure.
I'm posting this here to raise attention because
1. to fix this we need another protocol (extension)
2. this issue can't be fixed in a single application, it needs the whole stack
(wayland library, compositors, affected applications) to change
IMHO, this is the biggest important feature that's still missing for wayland to
be ready for production.
