Eu atualizei recentemente do Trusty para o Xenial; Tenho uma grande falha em relação ao meu scanner que só funciona algumas vezes agora, com aplicativos travando, ou simplesmente não reconhecendo mais o scanner como costumava, e trabalhando eventualmente depois de muita tentativa.
Eu olhei em volta para pegar alguns logs que você pode encontrar abaixo, espero que ajude a dar algum ponteiro, eu realmente não sei o que eu poderia tentar lá. O nome do scanner é "Samsung multifonction CLX 3185 FW"

Erreur de segmentation (core dumped)
Eu tive um problema semelhante ao atualizar o Ubuntu de 14.04 (LTS) para 16.04 (LTS) com a Impressora Multifuncional Samsung C480W. A impressão sempre foi boa, mas o scanner precisava de uma desinstalação / reinstalação com o pacote de driver oficial da página de configuração da Samsung :
sudo ./unistall.sh
sudo ./install.sh
