Today I wanted to set a screen timeout so my screens go in stanby mode when i'm away. Then I realized that the timeout was ideed set to 30 minutes but every time I came back to my PC both screens were on. So I reduced the screen timeout to 5 minutes and watched what happend. After 5 minutes, my screen locks and 5 seconds later went black but again 3-4 secons later it showed the lock screen again (the power-LED never went orange to indicate standby mode).
I already searched the Internet but I couldn't find my issue.
Of course feel free to ask if you need any system logs or other Information.
I am using Linux Mint 20.2 Cinnamon (5.0.7).
Thanks!
