i also have/had this problem. ThinkPad P14s 3rd gen (21J6) with AMD Ryzen 7 pro 6850u with Radeon Graphics. Ubuntu 22.04. Kernel was 5.19.0-46-generic.
Those solutions did not work: - no "Sleep Mode" option in my BIOS - did not manage to successfully access the Lenovo advanced BIOS menu to switch from Modern Standby power to S3 (the apparently secret advanced BIOS settings) - turned off "security chip" and secure boot in the BIOS - disabled Wayland What did work was to switch to kernel 6.12.14-060214-generic on Ubunutu 22.04 (#14). Now the suspend/wakeup cycle works. Laptop seems cool/normal and quiet for now. I did not try the amdgpu-install (#8). I do have the issue where "there is a short moment where the plain screen content is visible after wake up, but the screen is locked almost immediately." However, I can live with that. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.19 in Ubuntu. https://bugs.launchpad.net/bugs/2008774 Title: Ubuntu 22.04 not waking up after second suspend Status in linux-signed-hwe-5.19 package in Ubuntu: Confirmed 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://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).
