After the first suspend it wakes up just fine - it's the second suspend after which the screen stays blank and keyboard doesn't react (although the power LED starts glowing). It happens if I close the laptop's lid or do a manual suspend via the system menu.
I have a recent Thinkpad T14s with a Ryzen CPU, Ubuntu 22.04 is the only OS (if that's important).
What I tried:
- turn off security chip in the BIOS (https://askubuntu.com/a/1412049/424896)
- turn off Wayland and enable X11 (https://askubuntu.com/a/1412032/424896)
- I looked through the logs in /var/log but couldn't find anything obvious to me (but I'm not a Linux guru).
Anyone has an idea what might help here?
