Ubuntu 18.04 unable to wake from suspend I am been unable to wake my ubuntu laptop everytime I put it into suspend. 3 possible signs: * Sometimes it wake up ok * Sometimes, it freezes at wake and show screen before it freeze. * Sometimes it just a black screen but the keyboard backlights and laptop is running Anyone has any idea how to solve this? I had only found similar problem faced by people here System: Laptop Model: AFTERSHOCK Apex 17 (A reseller of Tongfang GK7CP7S) Same laptop but rebrands include: I am using Ubuntu 18.04, with Linux Kernel Version of 4.18.0-18-generic. * Walmart OVERPOWERED 17+ Cyberpowerpc TRACER III 17 XTREME * Cyberpowerpc TRACER III 17 XTREME VR * Eluktronics MECH-17 * Tongfang Mechrevo X8Ti-plus * PC Specialist 17.3" Recoil II (Europe) * Illegear Selenite * Clevocenter Nextcore

The solution was quite easy. Once I updated to the lastest kernel for Linux in ubuntu, the issue goes away. I am able to boot from sleep with no issue. Please refer to this: < A fresh install of ubuntu 18.04 would also solve this issue as the latest os image has the latest Linux kernel.
