Black screen with underscore after suspend/resume

[nicolas-t]

Hello,

Ideally I'd like to have my eGPU always on, and be able suspend/resume my laptop during the night like a regular computer.
I've tried the 3 methods but none of them seem to work for me.

When I resume my laptop I get a black screen with a white underscore, keyboard is unresponsive and l’m forced to stop the laptop and the eGPU before restarting.

Can you help me navigate the logs and to resolve this issue ?

For example after running all-ways-egpu configure egpu

I get this status:

Method 1 setup with following Bus IDs
0000:00:02.0 i915
0000:00:1f.3 snd_hda_intel
Method 2, 3 setup with following Bus IDs

0000:04:00.1 snd_hda_intel
0000:04:00.0 eGPU connected, not set as primary with Method 2
Method 1 auto switch at startup service

     Loaded: loaded (/etc/systemd/system/all-ways-egpu-set-compositor.service; disabled; vendor preset: enabled)
     Active: inactive (dead)
Press [Enter] to return to menu.

My setup is as follow:
Ubuntu 22.04
Gnome
Wayland
Razer Core x
Nvidia 3060

Thank you

New infos:
I get the same behaviour (black screen with underscore, forced to shut down computer) when restarting the Display Manager.

Then status:

Then, after restarting the display manager I get stuck on the black screen until I force a shutdown.
