## implements poke-1,0 's patch for hybrid Intel/NVidia
## see poke topic about it @ https://batocera-linux.xorhub.com/forum/d/1851-batocera-linux-5-22-with-nvidia-legacy-drivers-390-xx/9
# tested on batocera 5.22 5.23 Acer Aspire vx15 with Nvidia GTX 1050TI gpu OPENGL String: 4.6.0 NVIDIA 418.74/4.6.0 NVIDIA 430.40
# tested on batocera 5.22 Acer NC-VN7-791G-70M4 (Acer V Nitro Series) OPENGL String: 4.6.0 NVIDIA 418.74

line 10: use batocera-settings
line 26: /userdata/system is the right home dir

line 13: not necessary

line 13 18
command would be:
batocera-settings /boot/batocera-boot.conf uncomment nvidia-driver

or in it's long form
batocera-settings /boot/batocera-boot.conf --command uncomment --key nvidia-driver

You can use return code
[[ $? -eq 0 ]] || { echo "error occoured!"; exit 1; }

line 34
sh command is not needed - the files are already executable

Maybe some cosmetics and to make it more read and maintainable

Hi Broceliande, poke from Batocera forum sad to inform you about my case of gpu-hybrid GT740m of Dell Vostro 5470:
I tried to use your script but not work for me.
But I had progress using instructions of poke and part of your procedure for Batocera 5.22.
This is the manualy steps that I used:

1. mount -o remount,rw /boot
   nano /boot/batocera-boot.conf
   <remove the leading # from the nvidia-driver=true line>

2. create 99-nvidia.conf in /etc/X11/xorg.conf.d/

Section "Module"
Load "modesetting"
EndSection

Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "9:0:0"
Option "AllowEmptyInitialConfiguration"
EndSection

3. Edit xinitrc in /etc/X11/xinit/

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

4. Saving the changes

cd /recalbox/scripts/
./recalbox-save-overlay.sh

Reboot

Hi gameski,
Thank you for your report.
Unfortunately this page was not up to date and stayed at a wip state...
I din't think the link would be published, my bad!
I just updated it.
The actual version works for both 5.22 / 5.23
That would be great if you can test it on your hw so that we can add your GT740m of Dell Vostro 5470 to the tested list
With enough feedback we may can add it in next batocera's version
