No passado, meu laptop funcionava bem, mas nos últimos meses eu tive problemas com a tela do laptop não sendo capaz de acordar após certos eventos. Basicamente, depois que eu suspendo o laptop, há uma estimativa de 15% do tempo que a tela não liga depois que eu acordo a máquina. Uma porcentagem similar de telas em branco aparece quando a tela fica preta após um período de não atividade. Quando eu movo o mouse, ele pode ou não acordar de novo.
Eu revisei uma daquelas instâncias em que a tela não liga depois de ficar preta devido a não atividade (porque há menos entradas de log do que com uma suspensão). Durante o período em que a tela ficou preta e eu movi o mouse novamente, não havia entradas de journalctl. No entanto, no log do xorg, encontrei isso (não consigo decifrar os timestamps, mas este é o final do arquivo de log):

O único tópico relevante que pude encontrar foi: link - mas não há solução. Eu mantive meu sistema atualizado. Executando o Arch Linux com o i3 como gerenciador de janelas. Meu kernel é 4.14.52-1-lts. Quaisquer pensamentos o que poderia ser a causa disso?
