My Thinkpad T480 suspends and resumes successfully and with no problems. However, I noticed that if I hit Ctrl-C a few times during the resume process, I kill X and the screen saver and get a password-free access to the shell. This is a major vulnerability and I hope there is a fix for it. Has anyone been able to work out a security fix for this? At this point any other security measures like full disk encryption and firewalls are practically useless.
