right now there are 3 alternatives to notify-osd>alert boxes, morphing
alert boxes & morphing windows . rather than using 3 different ways to
present these alerts, just unify these alerts/notifications into a
single method that looks as good as the notify-osd, so then all forms of
notifications/alerts are covered by just 2 kinds of notifications
[notify-osd and the new system]
pls check this link [
https://wiki.ubuntu.com/NotificationDesignGuidelines/Comments ] for the
notification tags, mockup+screenshots of a persistent notification
concept, i think u may better understand what i'm trying to explain
here.something similar is required.
updates are ephemeral ONLY when all the programs are working properly,
but when some part of the system is broken a notification and a
persistent one is definitely required
[eg:1>since 9.04 uses the ATI driver for my ATI X1400 i have several X
restarts, which have caused me to redo a lot of work , but such updates
wont be notified until after 7 days of my previous update ,since they
are not security updates(mpt has promised to look into this update
classification for the new app centre in 9.10)
eg:2>as every update can help/break an app, firefox has slowed
drastically over the recent updates but i wont be notified of the next
1.the current system of notification of updates is definitely horrible,
un-notified window pop-ups is not a good process,
2.i have never noticed the pop-up immediately,usually i notice it after
my work is done or when i'm switching desktops.
3.the present behaviour forces me to keep the update manager window open
and if i close the update manager the i'm forced to remember about the
4.there is no quick access to the updates if dismissed,as was present
when the notification area displayed the update icon.
5.pop-ups are a regression since there are more better ways to force
updates/clean up notifications area.
there have been several complaints/bugs in both launchpad and
brainstorm regarding this problem.
and the default is set to display ONLY every 7 days which is even worse!
and as Matthew Paul Thomas says,the old system definitely makes no
sense, so there is a need for a persistent notification system , which
allows hyperlinks/actions as allowed by the
notifications are a good way to implement update notifications

i think u got this wrong. the user * wants * to notice the blinking list
but since the user has set the windows list to auto-hide , to utilize
the screen better,the blinking is not obvious enough.
he has to compromise on missing such notifications.
several others dont have the window panel, but instead use the docks for
windows list and the blinking of these docks is not good enough to get
ideally for window attention notification a time repeated window preview
as done by compiz would be nice, but the compiz window preview doesnt
allow interactions with the preview, whereas Windows7 has copied the
idea and allowed interactions[clicking on the preview brings the window
to the front]
but to bring all such notification in one spot, an actions allowed
notification could be used instead.

NO, one-clicks force quits are never good,
what i was mentioning was a notification that such a window/application
is misbehaving is never notified by the system, the user never realizes
this app freeze unless the user returns to the desktop where the app was
this is a huge loss of time, when the user thinks that the app is doing
its work in the background or the other desktop but rather has stopped
if there is a notification, clicking on the notification brings up the
app window along with the force quit dialogue , this way such
unresponsive apps dont unnecessarily eat away the system resources or

i was more concerned about the large file operations.
the method the Ubuntu uses for file operations notifications is by 2
ways, one is by using the metacity window and second is the notification
area where an unnecessary icon shows up on such copy/paste/move.
when notifications area was cleaned up why wasnt this removed?while
update notifier was!
such notifications are needed since there is a problem with system
performance when file operations are going on, for eg: there is a huge
drop in firefox performance and it drastically slows down during these
file operations, so user notifications using these notifications would
be good. to serve as a user reminder to not open more programs which
might cause program freezes and system hangs.

well, i agree with ur assessment that notify-osd could be used for this,
but there present system of opening child windows in the current desktop
and disturbing the user needs to be looked into.
notify-osd can be used to notify the synaptic process completions.

this is similar to file operations, there is usually drop in system
performance about the time such transfers are happening, so using the
notification tags , accept the transfer and

i do understand the team is focusing on refining the notify-osd. as mark
has asked for the notify-osds to be color tagged and properly
identified, this would be a good time to identify all other
notifications which do/do not require actions and simplify the
Also by doing so the OS would look more organized.
