Brightness notification does not work

gpm is the responsible to send the notification to notify-osd in order to display the bubble if it doesn't do it, it's a gpm issue.

Thanks for the report, we are currently undergoing some large notify-osd changes for GPM in Karmic. You can follow the status here:

bug 399492
bug 406396
bug 344886

Thank you for testing Karmic, and if you could, follow the above reports to see how they are progressing.

I have a very similar issue affect me too.
The notify-osd works fine (volume, network, IM, etc ) except for brightness~
When I am changing the brightness the original gnome notification show up instead.
I didn't have this problem when I was testing on Karmic Alpha3 and Jaunty.

Could you test the newest version of GPM (2.27.5-0ubuntu3)? The notify
OSD work has been completed. On the liveCD you can choose to upgrade
gnome-power-manager through synaptic in the Administration menu.

Instead, notify-osd does not show anything when changing the brightness of the screen. Everything works fine (volume, network, IM, etc ) except for brightness.

the brightness notification bubbles still doesn't work after upgrading GPM (2.27.5-0ubuntu3)

As of gnome-power-manager 2.28.0-0ubuntu1 screen-brightness changes via the special keys on my keyboard, do correctly trigger notifications displayed as bubbles rendered by notify-osd.

This bug still exist in my karmic beta install, that is changing the brightness using keyboard hotkeys does not trigger notifications displayed as bubbles rendered by notify-osd though i have gnome-power-manager 2.28.0-0ubuntu1 :(

moomex, what kind of hardware and brand (laptop, desktop, netbook) do you have? It could be that your system does short-circuit something in lower parts of the library stack, not exposing brightness changes to HAL, which gnome-power-manager uses to obtain info about any changes you make via these special keys. Thus causing no notification-bubbles to show up, because they are simply not issued by gnome-power-manager.

The laptop I'm using is HP Pavilion dv2196ea with nvidia graphic card GeForce Go 7200.

btw, what causes the short-circuit in the lower part of the library stack ?

Same problem here with Acer Aspire One 120L (first series) and Intel Graphics.
I'm using 9.10, just upgraded from 9.04 (where the problem originated, I think sometime in august),

Same here on Dell 1555 Intel Graphics.
Also upgraded from 9.04 to 9.10.

This problem reappeared with Raring.

same on ubuntu 12.10 with ati radeon 7470m
i can change brightness fn keys but no notification appears
