Summary
For Karmic Koala (Ubuntu 9.10) we want to improve the capabilities and user-experience of the notification-daemon notify-osd and further its integration into the Ubuntu- and Kubuntu-desktop. Changes are mostly internal to the notify-osd service, but there will still be some updates to patches applied to gnome-settings-daemon or nm-applet.
Release Note
The release notes will be refined as the implementation goes. However here is a first version of it:
The new included version of notify-osd x.y.z now provides increased rendering performance (and reduced CPU-usage) in general, notification-bubbles look nicer on non-composited desktops, non-critial notifications are now suppressed when using an application in fullscreen-mode or the screensaver is active (but e.g. notifications like "battery-low" still show up), on-screen time of notification now adapts to user behaviour (e.g. timing out is paused when a user hovers the mouse-pointer over a notification-bubble), notifications better adjust their positioning to users with multi-screen setups, old notifications (of exited or crashed applications) get removed from the notification queue, feedback-notifications for multi-media keys on keyboards are introduced again (e.g. Play/Pause, Stop, Forward, Backward).
Rationale
The original specification to improve of the notification-system used in Ubuntu written for the Jaunty Jackalope (Ubuntu 9.04) was not fully implemented in time due to its complexity and interaction with so many external applications. Furthermore the gather feedback and bug-reports from users introduced rethinking some aspects of the original specification, which has been updated since.
User stories
- The system (Network Manager in this example) reconnects you to your favorite network after resuming from suspend. It sends a notification
The user experience for the new notification system is described more thoroughly at https://wiki.ubuntu.com/NotifyOSD#Use%20cases (they are really user stories, though the link says "use cases").
Scope of the changes
Rendering / performance aspects
- surface tweaks, blur cache
- non-composited fallback mode
- adapt better to the DPI settings
Interaction enhancements
- improving the appearance and behavior (making composited bubbles more obviously unclickable, and non-composited bubbles classier, pause on hover, proximity hover, more subtle transitions)
- investigating whether we can use non-critical priorities for anything useful
Presentation enhancements
- positioning on (multiple) screen(s), depending on the type of notification
- experimenting with better positioning for the notification bubbles
- implementing the duration rules, so that notifications with longer text are shown for longer
- better handling of long backlogs of notifications
- accessibility, e.g. sound theme compliance and maybe alt text for icons
Audio application enhancements
- consistent feedback for multimedia keys
Context awareness
- better Do-not-Disturb mode (DnD) for full-screen applications, adaptive timer
- suppressing bubbles when any window is full-screen
KDE-integration
- (agateau and ScottK could provide the needed bullet points here)
Design
Contribute our experience to FDO
Helping to get the FreeDesktop notifications specification to 1.0
Testing
- a test suite for the rendering layer.
Implementation
UI Changes
The looks of notifications
- no non-composited case (designs still missing)
Code Changes
Mainly notify-osd has to be modified for the required enhcancements. But there are also external applications which need patches in order to meet http://wiki.ubuntu.com/.
Mandatory (applications in main):
- rhythmbox
- pidgin
- firefox
- evolution
- gnome-settings-daemon
- gnome-power-manager
"Nice to have" (applications in universe):
- gwibber
- thunderbird
- liferea
- empathy
- banshee
Migration
Application developers need to be aware of NotificationDevelopmentGuidelines and NotificationDesignGuidelines if they want to make sure their applications notifications seamlessly integrate with notify-osd on the Ubuntu desktop.
Test/Demo Plan
There is a manual test plan for the notification system at: http://testcases.qa.ubuntu.com/Applications/Notification
The test plan will be complemented with new test cases related to the new features or changes in this future release.
