Having the same issue. Screen flickers after waking up from suspend or
hibernate, when switching user I just get a black screen and can't do anything,
when switching terminal I can successfully login.

May or may not be of any consequence, but peeking at kwin_x11 with strace after
the black screen occurs shows the process stuck at:

restart_syscall(<... resuming interrupted read ...>

This just started happening for me in the past week or two on Arch Linux with
the stock repo packages. Had been working fine up to that point. Randomly after
a suspend-to-ram or monitor-suspend, the screen comes up entirely black with a
themed mouse cursor able to be moved.

I'm able to ctrl-alt-f2 into a terminal. I've tried poking around a bit to see
what exactly is borked but the best I can come up with kwin_x11 has trashed
itself in an unrecoverable and unlogged way. 

Trying to "DISPLAY=:0 kwin_x11 --replace" with or without the kquitapp5 /
kstart5 voodoo results in a compositing unavailable error in the syslog. I'm
not able to recover my session or any desktop environment once this occurs.

Following prior discussion, I saw nothing of note in kscreen-doctor: it outputs
the same 3 monitors enabled and connected before and after the black screen
occurs.

KDE Plasma Version 5.19.3
KDE Frameworks 5.72.0
Qt Version 5.15.0
Kernel Version 5.7.9-arch1-1 / 64-bit

Running on Ryzen 1700x & Nvidia GTX 1080 with binary driver 450.57 (I tried
rolling back to the previous driver, version 440, with no success).

Please let me know if there is any logging or triage I can do to help uncover
this mystery.

I have the same problem.
Steps to reproduce:
1) I go to System Settings > Energy Saving > Screen energy saving = "1 minute".
2) I wait for a minute, the screen goes to sleep.
3) When I wake it up, I see a black screen + pointer.
Sometimes I manage to restore it with Meta + P, going to a different screen and
coming back.
My system: Manjaro KDE - Plasma 5.18.4 + Frameworks 5.69.0 - Qt 5.14.2 - Kernel
5.5.18-1
Is there a solution or we just have to wait for this error to be fixed?
Greetings!
(Stay safe)

@7 Absolutely. `kscreen-doctor` (on text console) shows my `eDP1` is connected
but disabled. Enabling it via `kscreen-doctor` gives no error message, but the
screen stays black and the output of another `kscreen-doctor` call shows it
still as disabled.

Similar issue here, wake up from sleep(suspend) and external monitor connected
via dock will not wake up. Laptop display is disabled at this point so no way
of doing anything. Always have to unplug laptop from the dock to get laptop
monitor to come up, then plug back in and external monitor starts working or I
have to re-enable it in display settings.

Is this bug still happening on newer Plasma versions?

SUSPEND was fine until 2017MAR04 after I installed updates (could be
coincidence) 1- SUSPEND caused a reboot. Although it did not happen again. 2-
SUSPEND went fine, but at wake up, computer started, but lost screen (all
black) lost cursor, and system was not responding to keyboard.
I had to reboot.

I have worked around this issue by switching to the modesetting driver instead
of Intel's driver.

Almost similar situation - actually problem occurs both ways, but not always.

Example:
@home no external display attached, booted up, works. Suspend to RAM, next day
@work plug to dock with 2 external displays, open lid and whole system freezes,
only option is to do a hard shutdown. After booting up laptop + 2 displays
works like a charm, no changes needed. Suspend to RAM. @home resume from RAM,
mouse pointer is visible on far left, not moving. Blindly log in then xrandr
--auto works. 

Lenovo T460s (but similar problem happened with HP Elitebook 8470p + dock + 1
external display). 

Plasma 5.8.5
Fedora 24 (4.9.9-100.fc24.x86_64)

Unfortunately it was a short-lived wonder. :( 
After a 24+ suspend to RAM the screen didn't recover and I had to zap X11. I
did work, though, as reported in comment #2 but when suspending to RAM for
short periods of time.

I have solved my issue by reverting the following commit from kscreen:
b4b504696b638691ad96c75560e6599c44bea88c
It's probably not the right approach but it works for me :) and it might point
the developer into the right direction.
If I revert the following commit 367e55b7c172d54d068eb09f308e92368c294e9 from
libkscreen as well the screen still comes back after resuming but then the
.local/share/kscreen/kscree.log file is flooded with 

Current mode "" invalid, setting preferred mode ""

messages.

Similar situation here, without an external display. After suspend/resume the
laptop screen is black, no mouse cursor. CTRL+ALT+F[1-6] works but ALT+F7 does
not recover the graphic display.
The suggested workaround using xrandr works for me too.
