The old notifier used to stay out of your way. Get a little message or whatnot when you got a new e-mail. It was unobtrusive and didn't distract you while you're trying to figure out why some little bit of SQLAlchemy code is making too many calls to a database. But now, Canonical has found it necessary to make sure you're abundantly aware of every excruciating detail of your computer's operation. Productivity be damned.
I don't know whose bright idea this feature was, but whoever it is is trying to spread their terminal case of attention deficit disorder to the rest of the world. Fuck you. Grind up your Adderall pills and snort them until your heart shits out like a Chevy.
Anyway, if you don't know what I'm talking about, this is the offending window:
How To Turn This Thing Off
Open up a command line. Type this:
sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disabled
And restart your computer. You could probably restart the dbus daemon, but that makes a lot of things go ill on your machine.
This disables the notifier for good. Now you can get back to work.
