Suspend Issues

[iAmG-r00t]

(1) Issue/Bug Description: I am unable to suspend my laptop both when connected to two external displays and when not connected to an external device.

When connected to external devices and I try to send the suspend signal, it locks the screen goes dim then turns on once again. If I try to close the lid, it doesn't suspend it stays on and when I open the lid it starts to glitch like the video below and I have to force shutdown of the laptop.

FYI: I am using integrated graphics, with two external monitors

@iAmG-r00t any chance you have a bluetooth device paired? If yes, and you disconnect it, does suspend begin working again?

Also I believe this may be a duplicate of pop-os/system76-power#340

[iAmG-r00t]

@leviport even after disconnecting/turning off Bluetooth, suspend doesn't work.

[iAmG-r00t]

This issue on pop repo actually fixed it. Running this command: sudo kernelstub -a mem_sleep_default=deep then restarting my PC fixed it. Now I can suspend even when having Bluetooth device connected.
