Description

Description

As technology and the needs of modern computer users advance, X server has been proven less and less capable to keep up. Problems like serious lack of security, monolithic complicated design and even roadblocks to proper implementation of new technologies like touch screens and VR. Wayland has been decided as the future of not only the linux desktop but potentially the smartphone and tablet form factor too.

I propose to make our goal to migrate the core of the plasma desktop and make X server an optional compile and runtime depedency. In that way not only we will be giving our users futures that a modern desktop should have, like tear free compositing and security by default, but it will also pave the way for more advance futures like VR, touchscreen support and more that simply aren't possible without Wayland.

What it will take

  • Fix major breakage that still occurs
  • Implement missing functionality
  • Make SDDM run in Wayland
  • Start and stop X in every session dynamically based on necessity

How we know we succeeded

  • More people choosing Wayland, more bug reports for it
  • Wayland session is the recommended Default
  • X server doesn't have to be installed to run pure Plasma with core applications

T11054 should also be mentioned here, as input methods are also acting as a showstopper for certain users to even try out the Wayland.

This is also somewhat of a prerequisite for T11057 I think.

Although, I can't wait to see us switching to Wayland. I think this is slightly too "focused on one tech" as a goal. I'd rather see a lot of Wayland influence in the T11054 and T11057 goals mentioned than having a Wayland goal on its own which would overlook input methods for instance (which is exactly what the people who already switched for good did AFAICT).

there are some touch related things that currently need wayland (and probably will keep requiring wayland)

  • virtual keybaord
  • auto screen rotation
  • runtime detection for transformable laptops

And don't forget support for drawing tablets.

I agree with this. Can we find an angle for this goal that is not technology focused but expresses what will become better in the world? What is the underlying thing we want to make possible or achieve? What story would we be able to tell to get people excited?

Wayland by default would offer a better user experience. E.g. a tear free desktop, less power consumption, different refresh rates per screen, better possibilities to extend our desktop on mobile, better touch support and most important improved security. So yes, the goal as it is framed is focused on tech, but it can easily be reworded to focus on the advantages it gives us in comparison to X11.

I have reworked it to make it more focused on the way that it was discussed here. It is ready to vote by me.

Hey @fbampaloukas: I think the title of your goal could give a stronger impression if you stated explicitly what you want it to achieve. May I suggest Get KDE Working properly on Wayland Once and for All?

I hope this will include adding wacom and graphic tablet support under wayland in the missing functionality list.

Congratulations! This goal was selected as one of the three that we will concentrate on now. I sent you an email to coordinate the next steps.

My email to you bounced, @fbampaloukas. Could you email me at lydia@kde.org please?
