Ubuntu > dragging windows to desktop sides not working

Problem

Basically, dragging windows to sides of the screen isn't readjusting the window size to half the screen.

(I later found out this feature was called "window grid".)

Solution

I'm reposting the solution, because it worked.

In the terminal...

1. compiz --replace & disown
2. (I then needed to logout and log back in, as none of my windows were responding)
3. unity --reset

That should be it, windows now snap to half the screen, when dragged to the sides of the desktop.

Ubuntu Unity > remove Rhythmbox from the sound menu

Problem

Ubuntu 'Natty' 11.04
There's no (obvious) way to remove rhythmbox from the sound menu in unity.

Solution

According to the documents on the ubuntu wiki, rhythmbox must be removed by using gsettings. Execute the following in your console:

gsettings set com.canonical.indicator.sound blacklisted-media-players "['rhythmbox']"
