Bug description:
--- en
Always, almost every time I turn on my notebook, my LG external monitor keeps
blinking and it takes a while to actually connect to the notebook and the
external monitor screen to turn on. 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.

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.
