I have exactly the same issue which was asked in this thread: the screen remains black when I open my laptop after suspending it; I can not see anything but I can turn up and down the volume with the keyboard. However, none of the proposed solutions worked for me.
Here I will attach some more information:
- Computer: Asus Zenbook Pro 15 UX580GD
- OS: Ubuntu 19.10 dualboot with W10
- BIOS version: UX550GDX.308
- Graphic card: NVIDIA GeForce GTX 1050
- Driver in use: NVIDIA metapackage from nvidia-driver-440
- GRUB_CMDLINE_LINUX: "nouveau.modeset=0 nomodeset"
Tell me what additional information or command output is needed to spot the problem, becuase I suppose this is not enough.
