--- Comment #8 from Peter Wu <peter at lekensteyn.nl> ---
bug 92878 was closed as duplicate of this one, but it contains a reproducer and
logs in https://bugs.freedesktop.org/show_bug.cgi?id=92878#c18. That bug has
worse effects, the screen is simply blacked out.

Meanwhile I discovered that this also helps to revive the screen:
 xset dpms force off; xset dpms force on

This was tested with Linux 4.6.1-1 (Arch Linux), also KDE Plasma 5. CPU/GPU is
a i7-6700HQ.
