Can I run dconf-editor for a different user? (user gdm), or
find some other magical way to disable the notifications
that pop up while logging in?
In particular there is a persistently annoying notification
that my mouse battery is low. I'm fairly certain it is really
the keyboard battery it is talking about, but the dadgum keyboard has
a red light that comes on when it actually needs charging,
the gnome check is totally bogus and starts weeks before the
keyboard actually needs to be charged.
