Para criar um arquivo do iniciador do samba, primeiro execute-o no terminal - o nano é um editor de texto de linha de comando fácil de usar:
sudo nano /usr/share/applications/system-config-samba2.desktop
Em seguida, copie um dos textos abaixo (proveniente do arquivo do iniciador no meu computador Fedora, mas funciona no meu sistema Ubuntu ) e cole-o no nano( Ctrl+ Shift+ Vprovavelmente).

StartupNotify=true
Terminal=true
X-Desktop-File-Install-Version=0.21
Observe a Exec=linha e a Terminal=truelinha. O primeiro é o comando que será executado, enquanto o segundo significa que será lançado no terminal. Esse bit deve estar no arquivo do iniciador para que a senha do sudo possa ser digitada , mas se isso ocorrer automaticamente ou não exigir a senha, você poderá configurá-lo como Terminal=false.

Agora você deve encontrá-lo no painel, mas pode ser necessário fazer logout e login ou reiniciar para ver as alterações.
Se o iniciador aparecer, mas você quiser alterar o ícone, mude Icon=system-config-sambaparaIcon=/usr/share/icons/PATH/TO/REQUIRED/IMAGE

apt-getpara instalá-lo, veja se isso funciona.
