Eu tenho um problema desde a última vez que fiz sudo apt dist-upgrade em meu machon do Ubuntu como descrito aqui . No entanto, nenhuma de suas soluções funcionou, começando pelo fato de eu não estar usando o kernel de baixa latência.
Eu sigo todos os passos que parecem funcionar:
noveau . nomodeset em /etc/default/grub . GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1" também em /etc/default/grub (2 e 3 não foram definidos simultaneamente). apt purge ^nvidia e apt install --reinstall nvidia-384 . Enquanto (4) finalmente me dava uma tela de login, a saudade no gnome não funcionava.
sudo journalctl -ocat yields:

Essa última mensagem é repetida pelo menos cem vezes.
Removendo completamente o driver, deixe-me usar o computador novamente.
Depois de analisar este tópico , percebi que alterei o compilador padrão cc de gcc a clang (mesmo para c++ de g++ para clang++ ). Então a correção:
gcc . apt clean para limpar o cache do apt.
