black screen on Suspend

Question

My laptop is asus vivobook X556UQ. I have integrated intel graphic card and nvidia geforce 940mx.

After installing nvidia drivers and nvidia x server I have black screen when I awake laptop after suspend I get a weird error.

The screen is completely black, except for one line of code:

[ 44.351019] rtc_cmos 00:01: Alarms can be up to one month in the future

The only solution is to long-press the physical power button until the machine shuts down.

This solution works for me. Ubuntu 16.04, Asus laptop.

Open Applications -> System Tools -> Administration -> NVIDIA X Server Settings

Choose PRIME Profiles and then click Intel (Power Saving Mode)

If you're using the nvidia drivers, read this post: SUSPEND , RESUMING and WAKEUP with nvidia370.28. It tells how to configure your driver to work propely at wakening up from hibernate and suspend.

If you have any issue with looping at login screen, ubuntu stuck at login loop after nvidia drivers

I encountered the same problem, though I'm using Ubuntu 18.04. In my case, I solved the problem by switching from Gnome to Gnome Wayland. I don't know exactly why but it became a no longer issue. You might consider trying it.

Another option is to change the primary setting from Nvidia to Intel. You can easily do that by typing

sudo prime-select intel

in the terminal.
