I recently switched from Windows 11 to Fedora 38 on my 11th gen Framework laptop and encountered an issue with my external display connected via HDMI on an expansion card. After the laptop goes into sleep mode or is turned off, the external monitor takes about 2 minutes to wake up. The display is recognized in settings, and I can move the mouse between screens. I cannot reproduce this issue on a MacBook.
As a Linux noob, I would appreciate any troubleshooting suggestions.
UPDATE: I just tested with two other displays (portable with USB-C interface and TV) and this works just fine. Short “start-up” time on both. Seems that there may be issues with my Samsung monitor.
