Atualizar :
Para remover completamente o lançador do tempo de execução do seu script, eu desabilitaria o plugin compiz da unidade.
Temos um script desse tipo em Caixa de seleção , que estou colando aqui por conveniência:
#!/usr/bin/env python3

manage_compiz_plugin
====================
This script allows enabling or disabling compiz plugins using
gsettings. Changes take effect on the fly.

Para desativar o plug-in do unity:
./manage_compiz_plugin unityshell disable
Para restaurá-lo:
./manage_compiz_plugin unityshell enable
Primeira versão (usando a ocultação automática):
Para ocultar o iniciador de unidade, use os seguintes comandos:
dconf write /org/compiz/profiles/unity/plugins/unityshell/launcher-hide-mode 1
dconf write /org/compiz/profiles/unity/plugins/unityshell/edge-responsiveness 0
Para restaurá-lo, basta usar:
dconf write /org/compiz/profiles/unity/plugins/unityshell/launcher-hide-mode 0
dconf write /org/compiz/profiles/unity/plugins/unityshell/edge-responsiveness 2
