Google is preparing to test Ozone, making it possible for X11-alternative window systems on Linux such as Wayland or Mir to bring up Aura Chromium.
According to the official project page, Ozone is:
“Ozone is a platform abstraction layer beneath the Aura window system that is used for low-level input and graphics. Once complete, the abstraction will support underlying systems ranging from embedded SoC targets to new X11-alternative window systems on Linux such as Wayland or Mir to bring up Aura Chromium by providing an implementation of the platform interface.”
A new experimental flag added to the Chromium repository today talks about enabling Ozone:
“Use ozone: Use the Ozone/X11 platform implementation on X11″
Back in May 2020, the Chromium team had reported that they are “approaching the point when use_x11 && use_ozone can be compiled at the same time”
The next step in the development was adding a new flag to help users test this new platform. It was added to the Chromium code today.
