no such device after suspending

[markbaas]

In the settings I've enabled "Always enable the nVidia card before disabling" option to "No" in order to not get the 'no such device error'. However after suspending the laptop, again I got this error.

I have fixed this issue by creating a pm-utils hook in sleep.d that enables the card before suspending and runs ironhide-disablecard-on-powerup to disable it. I will post the hook.

I've put this in /etc/pm/sleep.d/99-ironhide

# This script was necessary to avoid getting no such device errors 
# running optirun after suspend

case $1 in
     suspend|suspend_hybrid|hibernate)
        # enable card to suspend
        /usr/local/bin/ironhide-enablecard
        ;;
     resume|thaw)
        # again, disable the card if no optirun is runninf
        /usr/bin/ironhide-disablecard-on-powerup
        ;;
esac```
