When I click sleep or sudo systemctl suspend, it seems to power down, screen turns dark for about 2 seconds, then it powers back up and goes to the lock screen.

This is the output of systemd-inhibit --list --mode=block:

WHO     UID  USER    PID  COMM           WHAT                                                     WHY                                                         MODE

Notables:

  • I have my laptop lid closed, and plug in an external monitor
  • I have played with various power settings, tried various combinations of lid, screen diming, and power button settings.
  • I have a disabled radeon graphics card sudo nvim /etc/default/grub contains (radeon.modeset=0): 
    RUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0card)
  • Have gone through the BIOS and disabled all wake from options, e.g wake from USB/LAN/AC etc.

I found this behavior was caused by an nvidia driver upgrade not removing some broken symlinks as outlined here: Ubuntu 20.04 suspend logs off and wakes up

Even though I get similar output as you above, it was not related to the issue and I can now suspend after removing the broken links.
