Public bug reported: This is 4.15.0-47-generic on a Dell Latitude 5580. Closing the laptop lid will suspend the system, and opening it will resume, and I normally get my xfce session or the xscreensaver unlock dialog. I recently suspended in this manner, but upon opening the laptop lid, nothing came up on the display. The power button was on, and the keyboard backlight responded to keypresses. Ctrl-Alt-PrtScr-[REISUB] had no discernible effect (PrtScr because I don't have SysRq on this keyboard). Neither did Ctrl-Alt-Del or Ctrl-Alt-F1 for a console. I needed to poweroff and poweron the laptop which of course caused the suspended session state to be lost.
