Bug Description
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. It happens only recently (I think after some kernel update, but I'm not sure about this) - before it worked fine for month (since I installed Ubuntu).
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:/
* turn off Wayland and enable X11 (https:/
* I looked through the logs in /var/log but couldn't find anything obvious to me (but I'm not a Linux guru).

There's many other screen related issues like this with 5.19.0-32 and with RYZEN processors with integrated graphics too.
My desktop is a RYZEN 5 2400G and I have the same issue with resuming from suspend or hibernation. I have a workaround though.
Once the monitor is blank but processor appears running, I do ctrl+alt+F2 to get to the console. The screen then flickers into life and then ctrl+alt+F7 to get back the the monitor. And all appears OK on the display again.
