Você está fazendo uma coisa errada. Você não pode instalar xserver-xorg-video-intel no Ubuntu com uma pilha HWE.
O pacote é xserver-xorg-video-intel-hwe-16.04 e já deve estar instalado por padrão.
Eu tenho tido alguns problemas no meu PC, eu postei sobre esse problema aqui cerca de três dias atrás, mas ainda não tenho solução; então eu decidi tentar consertar isso sozinho ...
A coisa é que eu descobri que nem tinha um driver intel instalado em primeiro lugar, como você pode ver no meu post aqui , quando tentei mudar para modesetting. Modesetting foi ativado desde o início, eu não tive que mudar ...
Então, tentei voltar para o antigo driver xserver-xorg-video-intel para ver se isso corrige o problema de distorção ...
Recebi as seguintes mensagens quando tentei instalar:
sudo apt-get install xserver-xorg-video-intel
[sudo] password for sakib:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:
The following packages have unmet dependencies:
xserver-xorg-video-intel : Depends: xorg-video-abi-20
Depends: xserver-xorg-core (>= 2:1.17.99.902)
E: Unable to correct problems, you have held broken packages.
O que devo fazer agora? É um mistério total porque eu não tenho o driver da Intel instalado, mas sim o modesetting; isso não aconteceu quando eu usei Mint, por padrão eu tinha Intel e depois mudei para modesetting ...
E agora isso!
Adicionado este parágrafo após a edição: encontrei este artigo que diz que modesetting foi habilitado por padrão para gráficos Intel Gen4 e mais recentes ...
Alguém, por favor, me guie através disso ...
Obrigado antecipadamente ...
