black screen after suspend

Bug Description

ubuntu 17.10 (gnome 3.24.2)
GeForce GTX 1050 Ti/PCIe/SSE2 - 384.59
AMD® Fx(tm)-4170 quad-core processor × 4
monitor 3840x2160 (dvi)

It happens on 1 of 3 times. I don't know what causes that.

When I am going to leave my pc for several hours I put it first on suspend/sleep mode. At about one third of resumes (from suspend mode) a black screen occurs and there is nothing I could do about it (except from hard reset). If something is pressed by keyboard like 'ctrl+alt+F1' or F2, screen starts again black (it searches for signal - backlight turned on - working mode). If nothing is pressed by keyboard, the screen closes after 1-2sec (backlight turned off - standby mode).

It sounds like you might have hit a gnome-shell crash, but we can't debug the issue without any details of what/where crashed.

Please have a look in /var/crash/ and for each .crash file run something like:
  ubuntu-bug /path/to/file.crash

GTX 1050 Ti (default driver xserver-xorg-video-nouveau 1:1.0.15-2)
AMD Ryzen5 1600
monitors: 1980x1080 x2

A similar phenomenon is occurring on my system.
In my environment,that do not react to the keyboard.

`ls -a /var/crash/` is nothing.

I did it. The only crash that did not open ubuntu-bug was "_usr_bin_gnome-shell.1000.crash". I don't know if that is relevant to the problem.

If I could do anything to add more info, please tell me.

The problem wasn't just a crash. It happens about every three in a row times that I returned my pc from sleep.

1. press sleep button on keyboard -> pc goes to sleep
2. press power button -> artful returns normally
3. press sleep button on keyboard -> pc goes to sleep
4. press power button -> artful returns normally
5. press sleep button on keyboard -> pc goes to sleep
6. press power button -> artful returns black without anything I could do to see anything on monitor. Although it seems that artful runs on background normally because on button press monitor starts again on black ..and then closes again

I posted another bug (#1717479) that maybe is related to this.

Please run:

And let us know the new bug ID that is created.

I ran "sudo ubuntu-bug /var/crash/_usr_bin_gnome-shell.1000.crash" and I get the errors:
1) on terminal: Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
2) on gtk window: Error('Incorrect padding',)

Although somehow, maybe after some recent update, problem was solved!

I encountered a similar problem during hibernation. I have created a report with `ubuntu-bug`. Also attaching crash logs for perusal
