External monitor (TV) is preventing Suspend?

[mrmikeroot]

Hi all. I have a Razer Book 13 laptop running Bullseye, connected to a Dell WD19TB dock, to which I have several devices connected (webcam, speakers, charger, USB hub, monitor)

I've found, through experimentation, that Suspend works correctly with everything except the monitor plugged in. However, when the monitor is connected, the laptop will resume immediately after suspending. The 'monitor' is a LG CX48, connected to the dock via HDMI.

Has anyone had experience with this? Anything I can try to fix this? I haven't been able to make any sense of /proc/acpi/wakeup. No idea which '4 letter code' might refer to my CX. I've tried searching, all I find is people having trouble with their monitors suspending or not suspending.

Thanks in advance for any advice.

Copy what is in your /proc/acpi/wakeup. You could experiment by making simple script that would disable one of them at a time to see which one is it.

Here it is. Any clue which device is the monitor, or is it just gonna be trial and error?

I know that XHCI is USB interface, but that doesn't seem to be an issue for you, as you said it works fine when no external monitor is connected. You can try this, after restart check /proc/acpi/wakeup and then again after you connect external monitor. To see the differences, then you can disable those new ones that appear and test it out.
