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. Meaning.. 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 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1710350 Title: black screen after suspend Status in gnome-shell package in Ubuntu: Incomplete Bug description: ubuntu 17.10 (gnome 3.24.2) 4.11.0-13-generic 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).
