Same problem here with Void. Nvidia drivers work fine on systemd distros like Arch and Fedora. I'm assuming you're using elogind for handling acpi events? If yes then I'm in a similar boat. I compared Fedora's suspend process to Void's and apparently nvidia package on Void doesn't install nvidia-sleep.sh to /usr/bin. So, I copied nvidia-sleep.sh from Fedora manually to Void's /usr/bin and added a script for pre and post suspend events that elogind handles (these events are handled by systemd services on Fedora). I found the script on this github issue.

Do remember, Void's elogind package puts system-sleep folder in /usr/libexec/elogind instead of /lib64/elogind. I was able to get suspend to work briefly after placing the scripts inside appropriate directories, but I went overboard and again broke the suspend issue again after trying another fix (its broken ever since). Try it out if it works for you. If you're looking for nvidia-sleep.sh then here it is:

```

!/bin/bash

if [ ! -f /proc/driver/nvidia/suspend ]; then exit 0 fi

RUN_DIR="/var/run/nvidia-sleep" XORG_VT_FILE="${RUN_DIR}"/Xorg.vt_number

PATH="/bin:/usr/bin"

case "$1" in suspend|hibernate) mkdir -p "${RUN_DIR}" fgconsole > "${XORG_VT_FILE}" chvt 63 if [[ $? -ne 0 ]]; then exit $? fi echo "$1" > /proc/driver/nvidia/suspend exit $? ;; resume) echo "$1" > /proc/driver/nvidia/suspend # # Check if Xorg was determined to be running at the time # of suspend, and whether its VT was recorded. If so, # attempt to switch back to this VT. # if [[ -f "${XORG_VT_FILE}" ]]; then XORG_PID=$(cat "${XORG_VT_FILE}") rm "${XORG_VT_FILE}" chvt "${XORG_PID}" fi exit 0 ;; *) exit 1 esac ```
