Ubuntu - problema com o gnome-control-central

Pessoal. Olha só essa.

Depois de algum tempo usando o ubuntu 16 LTS, resolvi partir para o 18 LTS.
Fiz uma instalação limpa no meu notebook, e pra minha surpresa, reparei que a inicialização estava demorando mais de 5 minutos (uns 8 pra ser mais preciso).
Pesquisa dali, pesquisa daqui, desabilitei a tela do splash do ubuntu e acabei descobrindo o erro “drm_kms_helper, flip_done timed out”. Esse erro pela minha pesquisa, acontece com alguma coisa com relação ao código do driver de vídeo (no caso do note, uma Intel integrada).

Consegui resolver o problema, aplicando a solução deste link https://sempreupdate.com.br/como-corrigir-kernel-error-in-drm_kms_helper-flip_done-timed-out-no-debian-ubuntu-linux-mint/ , ou seja, aplicando opção video=SVIDEO-1:d no grub.

Ficou legal mais ou menos um por um mês, quando em Janeiro, atualizei o sistema, e uma boa quantidade de pacotes foi atualizada. Para minha surpresa, quando cliquei no botão Configurações (gome-control-center), o sistema simplesmente encerrou a sessão, me jogando na tela de login novamente.

Já pesquisei bastante e não consegui achar alguém que trata-se desse problema. Alguém tem alguma ideia para ajudar?

Grato,
Rober

Tentou atualizar em fevereiro tbm?

Sim. Atualizadinho.
Está com tudo atualizado até o data de ontem.

Quando vc loga o sistema volta para a tela de login, é isso?
Já verificou se seu disco não está cheio?

Não, não é isso. O sistema carrega normalmente, somente ao clicar no botão configurações ele encerra a sessão. Ou, por exemplo, se for trocar o papel de parede, que abre as configurações, a sessão é encerrada, ou ainda, vou configurar a placa de rede, que tb abre as configurações.
O disco não está cheio.

Pessoal.

Pra ver se ajuda extrai um pedaço do syslog. Há uma série de Fatal Error 11.

Pessoal.

Depois de vários dias na luta consegui resolver esse incomum problema.

A solução foi a seguinte:
sudo apt install --install-recommends xserver-xorg-hwe-18.04
isso para mudar o Kernel para a versão 5, pois o kernel padrão da instalação 4.15-0.76 tinha bug com o driver da intel i915.

depois:
sudo add-repository ppa:oibaf/graphics-drivers
sudo apt dist-upgrade

depois de reiniciado o Xorg, ou o note, problema resolvido.
Valeu,
