Hello,
I am on a Thinkpad X260 that has been rock solid for a good year or so. I started having gpu related issues around 4.15. GPU is : Intel HD 520 (Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07).
Here is what I know:
4.15 messed up my docking station video out situation real good (like so). Reverted back to lts at 4.14, all was well.
Somewhere around 4.17 that was fixed that so I went back to latest. But weird stuff started happening.
When I suspend and immediately resume, all is well, so this is a pain in the butt to reproduce.
If I suspend and wait a good while, or screen goes off through DPMS, when it resumed, I get a black screen.
Underlying system is fine, if I flip virtual terminals (ctrl+alt+F2 then ctrl+alt+F1) all is well again.
Plus I get rare but unprecedented gpu hangs, X dropouts or mangled screen that is fixed by blind restarting X.
Behavior persistent across linux-4.18.16, linux-lts-4.14.69 and linux-ck-skylake-4.18.7. I have now reverted to a 4.13 kernel out of despair to see what happens, but did not have enough time to tell for sure whether issue is there.
Honestly, I was tempted to downgrade and ride this out but it's been a good while now. Machine was perfect until whatever it was that they poked around in 4.15.
Any advice on how to get to the bottom of this would be greatly appreciated.

Oh and I'm using the modesetting driver.

Also, when I revert back to 4.14 lts now, the problem persists, so perhaps whatever caused the issue was backported?

5 years I've lurked here without posting, and this is the post that pulled me out of my cave...
Arch running on Thinkpad X1 here, exact same issue.
Fast suspends don't trigger it, but if I'm away from my desk for a while and come back, screen is black until I change to another virtual terminal and back.
Kernel: 4.18.6-arch1-1-ARCH #1
You're not alone. I have coffee and a few hours in front of me.

Do you have this running anywhere?
xset -dpmsOffline
same issue here. the screen is totally black, but i can still operate the system blindly. I use modesetting driver on KabyLake 7200U.

I have the same issue, my current workaround is to have command
xset s activatehandy, if the screen goes dark, just run the command a few times until it brings the screen back.
