Finally got my wife away from Windows and on Fedora 40 (Gnome 46).

Now, when her PC goes to suspend and when she wakes it up, one of her 2 monitors doesn’t wake up.

Both are connected to HDMI ports (no dedicated video card, just the integrated card in her Ryzen 9).

Any ideas on what could be happening? I wouldn’t want her to go back to Winblows over something so insignificant, but she would.

    So it works on windows? If so, then it’s probably not a hardware issue.

    What I could recommend to help track down the issue:

    • test another distro, if possible - sitting here on NixOS it works for me
    • test another display manager (aka X11)
    • test another desktop (KDE, LXDE, whatever)

    If it’s none of the above, you might need to get your hands dirty

    • check if it’s always the same monitor
    • check the logs (journalctl --boot -xe) maybe something will jump out
    • monitor the reconnection of peripherials with sudo udevadm monitor
    • start it when everything’s booted up and everything’s plugged in
    • disconnect problem monitor then reconnect it and observe the output
    • suspend then wake the computer and check the output

    That might give you a hint of what’s going on.

    There’s a change something isn’t working in terms of drivers. You can probe her computer with the executable from https://linux-hardware.org/ and share uploaded result here. Maybe there’ll be an indication of a missing driver or something.
