Fix for suspend not working on some instances of Ubuntu 22 w/Nvidia drivers

Ubuntu 22 LTS w/Nvidia Drivers, sometimes causes courrpted text and or issues with suspend.

Amazing solution, found on Nvidia forums, created by devyn.cairns

gnome-shell is trying to talk to the NVIDIA driver after it has already gone into suspend, so it can’t respond. Linux tries to freeze the task, but fails because gnome-shell is waiting for a response from the driver and can’t be frozen.

The solution is to manually suspend gnome-shell using the STOP signal before the NVIDIA driver goes to suspend. Then use the CONT signal on resume.

The following steps helped solve the issue for me

Create the following files (and chmod them)

sudo vim /usr/local/bin/suspend-gnome-shell.sh
chmod +x /usr/local/bin/suspend-gnome-shell.sh

#!/bin/bash

case "$1" in
    suspend)
        killall -STOP gnome-shell
        ;;
    resume)
        killall -CONT gnome-shell
        ;;
esac

/etc/systemd/system/gnome-shell-suspend.service

Finally, run

systemctl daemon-reload
systemctl enable gnome-shell-suspend
systemctl enable gnome-shell-resume

After doing this, I was able to successfully suspend on Ubuntu 22 on Wayland.
