needed for the use case of files/folders on the desktop; check whether we want this use case; need to disable in “mobile” mode

* Disable nautilus background handling on devices images * Talk to design to determine if we need to display files on the desktop still and if yes, whether it should be the default for the Ubuntu Desktop

we should keep it for the desktop, users expect it on this UI format

goa-daemon

/usr/lib/gnome-online-accounts/goa-daemon

4.6M

5.0M

9.5M

75.3M

should not be running; superseded by signon-ui (Ubuntu Online Accounts); evolution-data-server is configured with goa support for GNOME flavors; need to patch it not to start goa needlessly

Seb to file a bug/write the patch to avoid starting goa in Unity sessions or if there is no goa accounts

Laney - can we simply remove the recommends from g-c-c to goa so that it's not installed by default (and seed it in the gnome remix instead)?->done, fix the issue for the default install, the bug is still worth fixing though

will be merged in Unity on the long-term, but not being worked on right now; could patch notify-osd to exit when idle, but notifications are so common (messages, volume changes, wifi connections, screen brightness etc.) that it's not worth restarting each time

gnome-screensav

12.1M

should not be running all the time; will be replaced by lightdm on the long-run; for now, we could either stuff the idle watch in gsd (but we'd like to get rid of it) and then move it to an upstart user session job when that's available (slangasek: nothing in the upstart roadmap covers starting upstart jobs based on a desktop idle timeout, I don't see that this can be moved to upstart)

Séb to check it out and see how hard it is

would like to replace this with upstart; currently monitors restart required, apport crash files, end of package installation, and if an update hook needs running

Séb to research all the things that require update-notifier to be running to check whether we can use upstart for these. bdmurray - in addition to file monitoring update-notifier also checks for CDs with packages on them, monitors for devices requiring firmware, and checks for a new release of Ubuntu
