I use Fedora 38 Workstation on an ASUS ROG Zephyrus G15 with an Nvidia 3060. When I just used the laptop screen, suspend and resume worked perfectly fine. But I recently got a Gigabyte M32UC external monitor that I use alongside my laptop screen. Ever since I started using it, my laptop wakes up immediately after suspend. Suspend initially seems to work and both screens turn off, but then the laptop automatically wakes up from suspend. I have tried disabling all the enabled entries in /proc/acpi/wakeup but that does not seem to do anything to fix the problem.
Here is some additional information that might help:
