Did you do any settings in BIOS related to Thunderbolt? Sometimes there is an option called "Force power" which basically turns power on the controller always. In normal cases that option should be disabled.
Also can you attach acpidump (along with the other things I requeted) of the system to the bug? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1708043 Title: Lenovo X1 Carbon Gen5 fails to resume Status in linux package in Ubuntu: Confirmed Bug description: Last week it worked fine, this week however if I open the lid for it to resume the power light flashes for a bit, then comes on solid, the but screen stays blank and the machine is unresponsive. I have to power it off / on again in order to use it. It might be related to the APST issue with Samsung NVMe SSDs, I'm not sure.
