On my X1 Carbon 10th Gen, I can confirm my 'sleep state' in UEFI/BIOS is set to "Linux" - as per lenovo's instructions, and I use Xorg exlsuively - via Ubuntu Mate.
I can confirm that this mitigates the problem, but still occurs occasionally.

YMMV, but since I lost a day I wrote my solution here in case it helps someone. -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1970957 Title: suspend problem Status in linux package in Ubuntu: Confirmed Bug description: I've installed Ubuntu 22.04 on the ThinkPad E480. Suspend functions ok intermittently. Some times it works fine, other times the computer does not enter the suspend mode (the screen gets blank, but the machine is still running and the ThinPad led is on, and there is no way out... no response from keyboard or mouse... the only solution is to switch off manually hitting and holding the power button), other times the machine does not wakes up from suspension mode.
