I am a new Ubuntu user. I just installed 12.04. To get Chrome on the Launcher, I clicked the BFB and searched for Chrome, then dragged that icon to the Launcher. However, when I run Chrome, it creates a second icon for the running chrome. Creating a second window creates a second triangle under the second Chrome icon, with the first icon not doing anything. It is also apparently not locked to the launcher and I can't remove it. Does anybody know how to remove the first icon? I have locked the second icon to the launcher and it seems to be working fine, but I don't want two icons.
I think this is a bug.
Try the following:
The above command will reset the icons the way they were when you first installed Ubuntu.
and remove the following line:
I hope this helps.
