As this is seen both with Nvidia driver and nouveau driver, I guess this is not related to these drivers, but an issue in Xorg, or some communication between BIOS and kernel/Xorg to wake up the screen again.

This issue is reproducible by running "xset dpms force off; sleep 5; xset dpms force on" in a terminal inside X.
