Black screen with mouse cursor after waking up from systemctl suspend

It looks like the formatting on xircon’s post got jumbled, it should actually be a one liner

  • /etc/modprobe.d/nvidia-power-management.conf
options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp

For i3-wm, I also had to do the following for hibernate, and as a bonus suspend also works.

LightDM

Summary
  • Create a file on ‘/usr/local/bin/optimus.sh’ with:
#!/bin/sh
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
  • Make it executable with:
sudo chmod a+rx /usr/local/bin/optimus.sh
  • Edit /etc/lightdm/lightdm.conf and set this at the [Seat:*] section:
display-setup-script=/usr/local/bin/optimus.sh
  • Just uncomment, and add the location of the script

Xorg

Summary
  • Create file /etc/X11/xorg.conf.d/20-nvidia.conf with:
Section "Module"
    Load "modesetting"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
    Option "AllowEmptyInitialConfiguration"
EndSection
  • The BusID should be PCI:1:0:0, but you can find yours using
lspci | grep -E 'VGA|3D'

Systemd

Summary
  • sudo systemctl enable nvidia-suspend.service
  • sudo systemctl enable nvidia-hibernate.service (not needed if only using suspend)
  • sudo systemctl enable nvidia-persistenced.service (if external monitor is used)

As you are only trying to get suspend to work, you may or may not need the xorg instructions.
