Desktop Team Updates
1

Hi everyone, below you will find the updates from the Desktop team from the last week.

If you’re interested in discussing a topic please start a thread in the Desktop area of the Community Hub (this site).
We also have our weekly meeting on IRC. We meet on Tuesday at 13:30 UTC in #ubuntu-desktop on Freenode. There will be an “Any Other Business” section at the end where you are welcome to raise topics. These topics might be discussed during the meeting, or afterwards depending on the time, depth of conversation, topic and so on.

Last week’s notes are here: https://community.ubuntu.com/t/monday-19th-november-2018/8701
Next week’s notes are here: Monday 3rd December 2018

rls-bugs:

  • NetworkManager IPv6 DAD lifetime behavior introduce security risk: I asked to upstream to release new version of nm 1.12
  • gnome session: Must ask twice to lock the screen: Fix committed upstream, I need to release it for disco and SRU it to cosmic and bionic
  • [SRU][regression] mozjs60 crashes with SIGSEGV on gnome-shell exit, in GetPropertyOperation() from Interpret() from js::RunScript(): @laney is taking care of SRUing gjs and mutter to cosmic

:white_check_mark: Merged/Uploaded
:eyeglasses: Under review

No change on release bugs from last week.

  • Tested and uploaded the fontconfig SRU
  • Build snap
    • Added more parts including: cogl, clutter, clutter-gtk and updated some existing parts
    • Fixed some more build issues
5
  • Switched tracker & tracker-miners to build with meson. tracker-miners doesn’t have as many meson options as it did for autotools. Previously, we were able to build-depend on universe libraries and disable the universe features in debian/rules. So for now, I’ve gone back to disabling the Build-Depends. It would be nice to add the options we need to the meson options so that we could sync tracker-miners from Debian again.
  • Poked at LP: #1740637 Maybe Seb can make a decision here on whether to go forward with removing python-appindicator and gir1.2-appindicator-0.1
  • Helped with package transitions
  • Spent time trying to fix up Debian’s ndctl package so that it could be used by a new libblockdev plugin (in Debian NEW queue).
  • Lots more work cleaning up libgnome and rarian reverse dependencies. There are only a handful left. I’ll post a Debian list soon.
  • Uploaded recent librsvg to Debian Unstable (& Disco), making some people upset with the impact on unofficial Debian architectures. I worked on a proposed solution but I need a ports person to prepare the initial upload for it. The librsvg packaging work was mostly done by Tim Lunn & Simon McVittie. I just did the part that involved upsetting people and trying to make those people less upset.

My week:

  • cups-filters: Released version 1.24.4, mainly to prevent cupsd taking all CPU when cups-browsed is hammering on it, by correcting cups-browsed’s way to handle timeouts. Fixes in pdftopdf and the PPD generator for driverless printing to avoid duplicate application of multiple copies options by both the filter and the printer. Code updates to build with newest versions of Poppler.
  • cups-filters: Further code fix to make it build with Poppler 0.71.0.
  • cups-filters: Tests for correct multiple-copy printing.
  • OpenPrinting web site: Continued coordination of web site renovation.
  • Bugs.

Mutter

  • Various fixes on wayland fractional scale resource-scale branch
    • Rebased on current master (upstream would like to merge this in the cycle)
    • Fixed scaling on nested views
    • Fixed a blurriness on offscreen textures when using fractional scaling
  • Xrandr scaling:
    • Changed the way we compute supported scaling values in X11, so that it works even before changing an output scaling, and in the way we can share the main code between X11 and wayland
    • Various refactoring neeeded to support native output scaling
    • Added settings for supporting fractional scaling in X
    • Done the actual scaling using only pure xrandr

snapd/ gnome-shell search providers

  • Continued working on implementing D-Bus service activation for snap services.
  • PR #5822 (systemd user unit support) is passing with against head. I ended up needing to disable the new spread tests on CentOS 7, since the method I was using to start the user systemd doesn’t work with the old version shipped with that release.
