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

  • Finally someone else with Aftershock laptop. Their support is good but Windows only. Usually my activity light is on (suspend should be blinking) and the power button light is on. My workaround is to notice when there's some delay in the previous wakes and restart befpre the wake fails. Sometimes pressing the power button works also

  • I actually found out that there is a fingerprint sensor on the touchpad that it’s use to wake the computer up. Due to the abnormal size touchpad, sometimes you might accidentally scan you finger and it puts the system to sleep. To bring it back on, just need to scan again on the top left button. You sometimes see a flashing blue light (default light Color). Don’t need to panic you turn on the power and it’s black screen still.

According to this answer on the XFCE forum, you should monitor what happens when you suspend the computer.

To do so, you could install xfce4-power-manager and check that your hardware indeed supports suspending, sleeping, hibernating, screen locking, screen saving, display on/off switching, etc.

I personnally had trouble resuming after suspending. That answer, along with the Power Manager documentation, helped me narrow down what I shouldn't do with my laptop. I am now able to suspend and resume as expected !

Hope it helps

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: https://itsfoss.com/upgrade-linux-kernel-ubuntu/ A fresh install of ubuntu 18.04 would also solve this issue as the latest os image has the latest Linux kernel.

For me, after trying everything I’ve found on the Web, what worked was to use bbswitch to switch to using a non-nvidia driver for normal usages, then switch to NVIDIA when needed.
