Haven't any familiarity with multiple monitors, so no direct experience. But, here are some suggestions. 1. Ensure that there is only a single screensaver operational. 2. Have you set the screen to blank at the same time as the power off? It is possible that there is an interaction or dependency between them. 3. Set the screen blank and power off to 1 minute for testing purposes. 4. Try different combinations of the three monitors. Switch the center monitor to the right or left. The symptoms you describe sound like it is slower to respond to the power up, and the system decides it is unavailable, and pushes its windows to the other two monitors. This will confirm if that is the case. Or, if it is the video card output being tardy on one of its outputs. 5. Try different combinations of two of the monitors. Write down the monitors you use, where they are located, and their behavior on awakening. 6. Use each monitor individually, and see what its behavior is. 7. Look in the journal after each test, journalctl -r. Are there any messages that indicate why the problem monitor has a problem? Are there any messages from the power control module about problems? 8. There might be a way to tell the screensaver to put out extra messages (verbose or debug). Set that if you can. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
