The screen dims, goes blank, and eventually locks but my system does not enter suspend mode.

I have suspend enabled on ac power under energy saving in system settings.

Someone else (https://www.reddit.com/r/kde/comment...en_on_suspend/) has reported that upgrading their kernel to 4.6 solved a similar-sounding problem.

Which kernel are you currently using?

uname -r

4.4.0-38-generic

missing firmware???

upgraded to 4.7

https://www.linuxbabe.com/ubuntu/ins...2-ubuntu-16-04

uname -r
4.7.2-040702-generic

got similar output and uname -r displayed old kernel until after reboot I noticed 4.7.2 in grub boot loader and then in Konsole.

Still not going into suspend.

Is the suspend problem still there?

Still a problem. And to clarify, it will go into suspend when I do it manually and press the button in the start menu. What I am trying to achieve here is to get the machine to go into suspend mode when it is unattended.

Power Saving settings are enabled in BIOS.
