I regularly see something *somewhat* similar on my Lenovo T530. Specifically, after running for a couple of days, it begins blanking the screen after a reliable 15 seconds of inactivity.
At first, I thought this might be a hardware issue with the lid/on-off switch, since I do close the lid when I'm away from the system. However, I don't see this in Windows 10 on this dual-boot laptop.
Interestingly, when the screen returns from black after I touch a key, it often returns to a different window (e.g., I was reading mail in Thunderbird when it blanked, but Chrome appears when it lights back up). AND, after a second or two, the screen switches back to the original window (e.g., t-bird). This tends to suggest something X-related.
In my case I see instants of black screen on a Lenovo P50 with
Fedora 24, using Intel graphics.
Looks like a refresh problem, or maybe something related to switching
the panel to the right gfx adapter (there is a dormant nvidia too,
with nouveau blacklisted).
My compositor is kwin.
Thank you, Roberto. My T530 also has Intel graphics, but I have not
installed the Nvidia drivers--only the Nouveau that was installed at
install time. Not sure what you mean about "switching" adaptors.
