One thing that’s probably worth talking about is the Ubuntu Summit coming up!

Anything we’d like to do together? The call for abstracts is open until July 20th - let’s plan our next Office Hours before that so we can finalize any ideas if needed?

Meeting Notes 2024-06-20

Below I have summed up the meeting notes for this month. Please let me know if you think that anything is missing or needs revision.

Attending

@raof @matthew-kosarek

1. xdg-toplevel-icon protocol has landed

  • @raof mentiones that there needs to be some fix for buffer lifetime management to make it fully work.
  • In the Mir team, we don’t have any particular need for it quite yet. However we will probably hook it up at some point because it is a useful protocol

2. QtMir Follow Up

  • During the development of Mir v2.16, we cleaned up a number of interfaces which QtMir was relying on
  • As such, @raof has been working on getting QtMir up to this new scheme in the spare time that he has: https://gitlab.com/RAOF_47/qtmir/-/tree/mir-2.16?ref_type=heads
  • The team will schedule some fixes for QtMir during “work time” as well
  • If anyone is interested in working with Mir’s platform APIs, feel free to take a look at it! This work should be a bit of plumbing. The more annoying part is that you need to know which platform to import the texture on, because we have a different platform per-GPU but Qt only wants a single platform for its rendering. Chris will ignore this problem for the first solution.

3. Window Management Test Harness

  • We are building out a generic test harness that downstream window managers will be able to use to validate theit window management scheme
  • This is build on Google’s test library
  • Check out that pull request here: Pull requests · canonical/mir · GitHub

4. xdg_decoration

5. wp_viewporter

  • @raof has this functioning currently and is currently writing some wlcs tests for this protocol, specifically in terms of error handling

6. Input Configuration

  • @alan_g has hooked up the configuration of libinput to Mir’s configuration system
  • You will be able to configure libinput via command line arguments, environment variables, and the Mir configuration file

7. Mir v2.18 Soon

  • Expect a new minor release of Mir soon!

8. Atomic KMS

  • @raof will be working on migrating to atomic KMS very soon, which will enable a number of interesting graphics-related things

9. Miracle Spin

10. Ubuntu Summit

  • The Ubuntu Summit has been announced in The Hague at the end of October
  • We are going to submit 1 or more abstracts about Mir
  • If you are using Mir for any exciting reason and are interested in presenting, feel free to reach out

11. Chatting about upcoming work

  • @matthew-kosarek is excited about portals, specifically as they relate to screen sharing
  • Mir is getting better and better everyday!
