External monitor not turning back on after being woken from sleep

After I fixed the script (and the fix is still active), both the laptop and external monitor turned back on after being woken from sleep. However, in the past few days, the laptop turns back on while the external monitor does not.

Have you tried undoing your changes to said script? You can temporarily override the DPKG diversion by installing a symbolic link to nvidia-sleep.sh.distrib:

cd /usr/bin
# make a backup of the local version
sudo cp -f --backup=t nvidia-sleep.sh{,}
sudo ln -sf nvidia-sleep.sh{.distrib,}
