For the external monitor to work I change the video settings using Ctrl + P and turn the monitor off/on several times. In Kubuntu it is recognized but when it blinks the system thinks the monitor is off. I'm using Kubuntu 23.04, I've used other distributions on the same hardware and this problem hasn't happened. I believe it's something with KDE. --- pt-br Sempre, quase toda vez que ligo meu notebook, meu monitor externo LG fica piscando e demora para realmente conectar ao notebook e a tela do monitor externo ligar. Para o monitor externo funcionar eu mudo as configurações de vídeo usando Ctrl + P e desligo/ligo o monitor várias vezes. No Kubuntu ele é reconhecido mas quando fica piscando o sistema acha que o monitor está desligado. Estou usando o Kubuntu 23.04, já usei outras distribuições no mesmo hardware e esse problema não aconteceu. Eu acredito que seja algo com o KDE.
