I installed DbVisualize in Ubuntu 12.04. Now I don't want to use it anymore, so I deleted the folder "DBVisualizer" in my Home folder. Problem is I can still see the icon in the Dash.
How could I remove it completely from my system (for other apps too)?
Dash picks up its entries from .desktop files placed in
/usr/share/applications
and~/.local/share/applications
.Deleting the .desktop file corresponding to your program should remove its entry from Dash.
I had the same issue, this seems to be quite a common problem. Ubuntu should include a MENU editor by default.
First I uninstalled the application, then I deleted all references from the following folder:
Rebooted....but never resolved my issue.
So installed this MENU editor:
and delete unwanted icons.
Actually, you should delete programs through Synaptic or Software center, but not simple by deleting the application folder. Also, you can delete the application icon from the unity dashboard by right-clicking it and than clicking on the "Unlock from Launcher".
