An unexpected journey

Software

Since my last post quite some progress has been made in getting KWin working on top of a Wayland compositor. My main focus of work has been on the input stack. This is something I am not really familiar with as so far we did not have to care about it.

As some might know input handling in X11 is very insecure. Every application is able to listen to every key event. And in the KDE workspaces we obviously make use of these “features”. For example the global shortcut handling is implemented as a kded module listening to all key events and notifying the application via D-Bus that the shortcut got triggered. In a post-X11 world this will not work any more: applications are no longer able to listen to all key events.

One of the important tasks therefore is to not send all input events to the X-Server but just to the window which should get it, or to handle the input events inside KWin and discard them without passing to the applications.

    It's been five almost five months since the developers behind the Debian-based Devuan GNU/Linux operating system launched the second Beta version towards the first stable release of the OS, and they now announced the Release Candidate. The Devuan project continues its vision of providing a libre Debian fork without using the systemd init system, and the Release Candidate (RC) version brings the GNU/Linux distribution closer to a final release. The interesting fact is that this RC appears to be stable enough to be used for production work.
