--- Comment #1 from Nate Graham <n...@kde.org> --- Assuming I tested this correctly, I can't reproduce the issue with my HP Z24m G3 monitor, which is connected to my laptop via a USB-C 4.0 cable (not Thunderbolt) providing DisplayPort signal, power delivery, and USB. I tested as follows: 1. Plug in laptop and close lid -> external screen stays on as intended 2. Configure system to sleep after one minute -> wait a minute, let it sleep 3. Open lid -> system wakes and both screens become active 1. Plug in laptop and close lid -> external screen stays on as intended 2. Configure system to never sleep, but turn off screens after 30 seconds -> wait 30 seconds, let screen turn off 3. Wiggle the mouse -> screen turns back on Could be an issue with your monitor. -- You are receiving this mail because: You are watching all bug changes.
