No Gerenciador de Pacotes Synaptic, o backport do Ubuntu quer instalar o systemd (admin, main, versão 204-5ubuntu20.20) no Ubuntu 14.04 com o kernel 3.13.0-105 genérico e deseja desinstalar os seguintes arquivos. Por quê? A desinstalação desses arquivos tornará meu sistema inutilizável?

Parece que um ou mais desses pacotes (provavelmente o material do X.org) no seu sistema é incompatível com o systemd pacote (s) e os outros pacotes dependem desses pacotes incompatíveis. Daí porque o Apt quer removê-los para instalar systemd .
Se você disser ao Apt para desinstalá-los, você não terá mais uma interface gráfica do usuário até reinstalar o. Seu sistema ainda será utilizável, embora apenas a partir de um terminal virtual.
