Every Frame Matters

Hello fellow readers, and welcome to an other installment of the least regular blog on the planet (or actually, not on the Planet anymore).

Last time, we were about to release 3.8, and this time, 3.10.0 is already out and we're working hard for 3.10.1, so today I want to talk about one of 3.10 features, that is, Wayland done in the GNOME way.

I worked hard on it during this summer, as part of my internship in Red Hat (which I'd like to thank once again for the opportunity), and others like Phoronix and Slashdot already covered it extensively, but what changed today is that finally all the bits are in place for wider testing on Fedora 20.

Once again, I'd like to point out that this is just a tech preview, and there are many huge regressions (listed in the 3.11 feature page). Some can be fixed using jhbuild and the wip/wayland-work branch, some are just not implemented yet, and some are bugs we don't know about. So try it, complain if it crashes, but don't expect to do any real work on it, and don't assume that the final wayland experience will be the same as now.

How to try it? First, you need an up to date GNOME 3.10 (gnome-shell >= 3.9.92-3.fc20), then you need the very latest X server (xorg-x11-server-Xorg >= 1.14.3-4.fc20, currently only in testing) and intel driver (xorg-x11-drv-intel >= 2.21.15-4.fc20, from updates-testing).
Then, there are two major modes now. The first one is nested inside an existing X11 session. From a virtual terminal, run "mutter-wayland --wayland".

Alternatively, you can run a full GNOME session in a different VT. Just go <Ctrl><Alt>F2 and run "gnome-session --session=gnome-wayland".
And this is what you get:

Doesn't look very different from a X11 GNOME session? Then I did my job well :)

To leave it, just log out from the menu. If you get stuck and can't logout (which can happen for some reason, probably a timeout issue in gnome-session), run "killall gnome-session gnome-shell-wayland" in a terminal.
Note that keybindings are not in 3.10, so VT switching only works if you do "sudo chvt" from a terminal.

More details on testing gnome can be found in the GNOME wiki

Under the shell of the developer

So, it's 3.7.92 time! Release notes are almost out, and if everything goes according to the plan, we'll be releasing our next stable version on March 27th.

As a member of the shell team, the big news is another successful round of Every Detail Matters. Go and see for yourself the eco-friendliness of that page: almost every line is green.
Among the many bugs, I'd like to highlight one, that has probably bugged each of you since 3.0: OSDs and global keybindings (screenshots, volume, input source, brightness) work in the overview, the screen lock and when a modal dialog is up.
Many thanks to Florian Müllner for implementing it!
About the rest, suffice to say that we tried to fix all the small annoyances and inconsistencies in the shell. And the release notes already include a very nice screenshot of them, so I won't steal the surprise until we're out.

Then on, the features side, it deserves a mention that we have a new application view, with frequently used apps and custom folders. I like it!

Going back to what I did, I already blogged on the most noticeable feature I worked on this cycle, notification filtering. But the awesome GNOME folks started patching all applications in this universe, so the panel looks a lot better now:

Then, it was a slow February, all exams out, I started hacking on Gjs. The result is an application framework that I will propose for 3.8. You can see a demo (which doubles as a template) at
But I needed a real application to validate what I was writing, and so GNOME Weather was born - again. And people started saw there was activity, I got a bugzilla product, and bam, magically I had patches from everywhere. Now say, isn't free software the best?
But wait no more, here is Weather 3.7.92 in all its glory.

Once again, thanks to Paolo Borelli, Cosimo Cecchi and William Jon McCann for all the help and code, and thanks to all flickr artists that, by choosing a free license, contributed to the success of this app.

So, what are you waiting for? Go grab GNOME 3.7.92!
Tarballs are at the usual location, and so are jhbuild and ostree. And I'm told the build server offers pre-built VM images, if you're into that.
