O sistema congela às vezes depois de retomar da suspensão

Question

Eu tenho tido esse problema por algum tempo. Às vezes (eu acho que uma em cinco vezes) meu laptop congela completamente depois que eu tento retomar a suspensão. A tela exibe o protetor de tela ou a solicitação de senha, completamente congelada; o teclado e o mouse não funcionam, nem mesmo o Caps lock ou Ctrl + Alt + Fn .

Estou tentando resolver isso há semanas, sem sucesso até agora. Isso é o que eu tentei (com base em respostas para problemas semelhantes que encontrei na internet), reiniciando após cada um deles:

1. Remova o comentário SAVE_VIDEO_PCI_STATE=true no arquivo / etc / default / acpi-support .
2. Adicione resume=UUID=<swap-partition-uuid> à variável GRUB_CMDLINE_LINUX_DEFAULT no arquivo / etc / default / grub e execute update-grub .
3. Verifique se o UUID da partição de troca acima mencionado está correto em /etc/initramfs-tools/conf.d/resume e / etc / fstab .
4. Atualize o kernel para a versão mais recente.
5. Reinstale o pacote xserver-xorg-input-all .
6. Adicione atkbd.reset i8042.nomux à variável mencionada no item 2 e execute update-grub .

O que mais posso fazer para resolver este problema? Obrigado.

Algumas informações sobre o meu sistema (posso adicionar mais, se necessário, é só pedir):
