Disabling annoying popup notification on Gnome Ubuntu
So I'm on Ubuntu and I use Pidgin and Tweetdeck. Everytime someone sends a chat message to me, or someone I follow tweets, a black notification message pops up on upper right corner of my screen, showing what who they are and what they say. And because I follow almost 500 people on Twitter, this notification pops up very frequently and becomes annoying distraction. I needed to rid them.
This is what I did, which worked for me:
sudo apt-get -y remove notification-daemon
sudo apt-get -y remove notify-osd pidgin-libnotify
