Code:
echo 'mem' > /sys/power/state
After wake there is no video output. Resume works properly with nouveau but unfortunately nouveau does not support the advanced functionality of my cards. This is with gentoo-sources 4.12.12 and nvidia-drivers 384.90.

I found reports of this on other distributions but no solutions.

Aside from the lack of video output, does the system otherwise resume successfully? It is available over the network, responds to keyboard input, etc.? If so, check the kernel log and/or ask the nVidia developers for help. Since Nouveau can do it, your card is clearly able to do it.
