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.

    I’d probably:

    1. make sure it can be reliably reproduced using something like systemctl suspend
    2. try swapping the cables and see if it still happens on the same screen, or the same port
    3. look at journald/dmesg output for the period from suspend to resume

    When the screen fails to wake, are you able to get it back by powering it off, or by unplugging it? Is it X or wayland?
