Wayland porting continues

Mosaic by Alison's Eyes.

It has been a while since I’ve last reported progress on the ongoing port of GNOME to Wayland. Giovanni did an unbelievable amount of groundwork in mutter and gnome-shell during the 3.10 cycle. After that all landed, we took a bit of a break to catch our breath, while GNOME 3.10 matured to 3.10.1 and now 3.10.2.

Now it is time to pick up the effort again, and sort out what remains to be done for full Wayland support in GNOME 3.12. From a high-level perspective:

  • Wayland sessions in gdm
  • Keyboard handling (layout switching, on-screen keyboard, accessibility, input methods, shortcuts,…)
  • Pointer handling (pointer barriers, accessibility, better touchpad support,…)
  • Window management (lots of details)
  • Application support (gstreamer, clutter-gtk,…)
  • Application testing and porting

If this sounds like a lot of work, that is because it is a lot of work.

Thankfully, quite a few of these things are already in progress or at least being planned. For example, a new xdg_shell interface has been discussed for a while to handle window management. For keyboard handling, Rui has started by implementing layout switching for weston. A new library for sharing input handling code is beginning to take shape too. clutter-gtk support needs subsurfaces, for which Jonas has patches here.

But there is still a lot to do, and any help is welcome. If you feel adventurous and want to learn about Wayland, please join us – there are tasks in all levels of difficulty here, you don’t need to be a ├╝ber-X-hacker to find something useful to do.

More details on the Wayland port, including the list of open tasks, can be found on the wiki.

  1. Insider tip: Mir was a ruse by Canonical to speed up Wayland development. They intend to eventually scrap Mir (when it has served it’s purpose) and use Wayland. The people behind the idea are patting themselves on the back quite a bit at the moment.
