Ubuntu – Can’t wake up from suspend

17.04suspend

My notebook with Intel+Nvidia card can't resume after suspend. I have Kubuntu 17.04 installed with 4.10.0-19 kernel. I'm using Intel GPU (Nvidia driver is not even installed). This issue has been existing with 16.10, too.

When I try to resume after suspend, everything freezes at the half visible login screen. Even keyboard doesn't work (when I press CapsLock or NumLock, LEDs doesn't light up)

Any help with examining the issue is appreciated.

Solution: Upgrade to kernel 4.13.1.

I was struggling with this issue on my Lenovo G40 laptop since 2 years. Recently I upgraded to the latest kernel 4.13.1. The problem solved 100%. Works perfectly. Tested with Ubuntu 16.04, Ubuntu 17.04, CentOS 7, Fedora 26, Linux Mint 18.2, OpenSuse 42.3. All OS work perfectly with kernel 4.13.1. When I close and open the laptop lid, it wakes up from suspend smoothly.
