Eu vi vários problemas sobre o congelamento da GUI do Ubuntu 17.10. Estou enfrentando esse problema também. É realmente irritante, mas acredito que meu problema é mais "preciso".
Meu computador tem duas GPUs RADEON, com três monitores. É autologado pela conta da minha esposa.
Engraçado é quando eu mudo para minha conta. Esta versão do Ubuntu não gosta de lidar com duas contas registradas. Porque, enquanto uma conta está ativa, a outra congela.
Por exemplo, chego em casa e faço o login às 16:05. Eu trabalho por cerca de 30 minutos. Quando minha esposa precisa trabalhar e nós trocamos de sessão, o relógio da sessão dela está aparecendo 16:05! Congeladas. Apenas o mouse se move, nada mais. Às vezes, a sessão é desbloqueada e tudo fica normal. Mas às vezes, a única solução é:
sudo pkill -u <username> -KILL
Aqui está a saída do dmesg -T:
