-two days ago i did a revert update and it broke my lockscreen, i had a SDDM problem which i tried to fix then los hope and did a new installation.
Now i have weird problem where my screen goes black and flickering light when i plug hdmi of a second monitor.
-a second problem also showed up; when screen turn off after a period automatically i can’t relog; the screen is black and stays that way. the weird about it i still can lock screen by myself and relog so this problem only happens when screen turns off.
i tried reinstalling video-linux and rebooted but still nothing.
i think sddm has a problem and dont know why after this new installation. Now im looking on how to reinstall sddm.
Any help, guidance and links to this problem would be appreciated. Thanks alot.
