Ubuntu 20.04 hangs after sent to Suspend mode

cx flag

I am running Ubuntu 20.04.4 LTS on Lenovo Thinkpad P1 (and using Grub to dual boot between Windows and Linux on two physically separate SSD drives).

Recently I let the system install some updates. After that, I'm not able to send the machine to Suspend mode. I am not using the lid to suspend it since I use external monitors. I tried the UI command and also command line systemctl suspend. Both don't work:

  • screen goes blank
  • the laptop light on the power button is still on
  • I hear the fan running
  • I can't wake the system
  • I have to hard reset the system by pressing the power button for 5 seconds

What could be wrong? Which logs should I look first? What to search for in the logs?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
