Monitor won't wake

Hi all,

Wondered if anyone had any had any clever ideas; my monitor doesn’t seem to detect a signal from Linux after either a suspend or a boot if my monitor is turned on after my machine. Always works the other way around.

I’m on Arch Linux, Cinnamon, GTX 960 with proprietary nvidia drivers. Tried many different display managers, and it appears to log on, even if it doesn’t display when I enter a password.

I’ve also tried systemctl enable nvidia-persistenced.service -f which didn’t do anything

Any ideas?

Thanks in advance
