Congratulations. You have your Intel GPU managing screen monitor. But from this
Code:
root@live:~# xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x44 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 0 name:modesetting

It seems there is something wrong with Nividia?

Look at mine.
Code:
enrique@live:$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x6b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 4 associated providers: 0 name:modesetting
Provider 1: id: 0x45 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 0 associated providers: 0 name:TURKS @ pci:0000:01:00.0

See how I have 2 providers!! Provider 1 "Turks" is my AMD.
The good part is that lsmod | grep -i -e "nvidia\|nouveau\|i915" shows your nvidia drivers installed. Now you need to look into dmesg & cat /var/log/Xorg.0.log[/b] to look for errors.

Now the Theory. You have what people called a Hybrid GPU setup as you have Intel at the moment running your screen and Nvidia in the waiting. If clinfo works, then this is perfect setup for running Opencl in Nvidia.

This MESA commands will force the use of Nvidia firsta one will ask info, the secong will drive the wheels. Firts we do it with Intel so that you know what to expect with Nvidia.

Intel
DRI_PRIME=0 glxinfo -B
DRI_PRIME=0 glxgears

Nvidia
DRI_PRIME=1 glxinfo -B
DRI_PRIME=1 glxgears

But you can try to twink a little to see if you can also get the opposite. Running screen in NVIDIA and Opencl in Intel. But it requires experimentation. Just for info look at:
Code:
https://bbs.archlinux.org/viewtopic.php?id=259300

NOWWWW I suggest to leave it as it is and see if clinfo works, then try to compile the add_numbers Opencl sample.

Test #1 go to your Boot menu I do not remeber what ot was but maybe geany /mnt/sdb1/grub.cfg

Then add nouveau.blacklist=1 nvidia-drm.modeset=1 to see if it work after reboot
menuentry "BusterDog19" {
linux /BusterDog19/live/vmlinuz1 nouveau.blacklist=1 nvidia-drm.modeset=1 from=/BusterDog19 changes=/BusterDog19/live/changes.dat
initrd /BusterDog19/live/initrd1.xz
}

menuentry "BusterDog19 save changes only on exit" {
linux /BusterDog19/live/vmlinuz1 nouveau.blacklist=1 nvidia-drm.modeset=1 from=/BusterDog19 changes=/BusterDog19/live/changes.dat
initrd /BusterDog19/live/initrd1.xz
}

reboot and see whats new here a few commands to see if error went away, get info and if clinfo is working
Code:
xrandr --listproviders
cat /var/log/Xorg.0.log | grep -i NVIDIA
clinfo
DRI_PRIME=1 glxinfo -B
DRI_PRIME=1 glxgears

Did not work Test#1 then we need to dig deeper. You never send all data I ask. In terminal do

Code:
mkdir /mnt/sda3/nvidiadriver/
dmesg > /mnt/sda3/nvidiadriver/mydmesg.txt
cp /var/log/nvidia-installer.log /mnt/sda3/nvidiadriver/nvidia-installer.log
cp /etc/apt/sources.list /mnt/sda3/nvidiadriver/sources.list
find /lib/modules/4.19.0-19-amd64 | grep -i -e "nvidia\|\drm" > /mnt/sda3/nvidiadriver/modules.txt
lsmod | grep -i -e "nvidia\|drm" >> /mnt/sda3/nvidiadriver/modules.txt
Now we are going to unload the module and reload to see what mesages produce

Open 1 terminal
Code:
sudo tail -f /var/log/{messages,kern.log,dmesg,syslog} 2>&1 | tee mnt/sda3/nvidiadriver/mosetinglogs.txt


In the another terminal do
Code:
modprobe -r nvidia_drm
modprobe --verbose  nvidia_drm modeset=1

See what we doing, in one terminal we look at responses in the other we unload and reload module. Stop both terminal windows, Then zip folder /mnt/sda3/nvidiadriver as send me the files.

Just as a comment. I search net again. And someone suggest to install this way
Code:
apt install nvidia-detect
nvidia-detect, this told me nvidia-legacy-390xx-driver
apt install nvidia-legacy-390xx-driver
update-alternatives --config nvidia and select the legacy driver
apt install nvidia-legacy-390xx-opencl-icd
apt install clinfo

We did all but we may had miss to do
Code:
update-alternatives --config nvidia
And select the legacy driver. Then

Code:
apt install nvidia-legacy-390xx-opencl-icd

Then test with
Code:
ls /etc/OpenCL/vendors
clinfo

HOLD YOU HORSES!

I am so sorry you did post Yesterday at 16:48 while I was writing my last post.
Now lest see whats new.
1) xrandr --listproviders show now that you have 2 providers. Not perfect as you will love to see instead pf name:modesetting you like to see nvidia.
2) Xorg still reports [ 38.362] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

But for openCL it may be good 1rst steps.
3) clinfo show just waht you need. Perfect

4) Missing DRI_PRIME=1 glxinfo -B & DRI_PRIME=1 glxgears >> bash: glxinfo: command not found
Thai is fine you can installed it with "apt install mesa-utils" But before you do anything PLEASE make a BACKUP copy of your change.dat so if we break it in the future, you can restore quickly.

After you do make a backup then add whats missing.

Code:
apt install mesa-utils nvidia-legacy-390xx-opencl-icd

and do just in case do to see if NVIDIA show up.
Code:
update-alternatives --config nvidia


Listen DO NOT get frustrated. Linux Setting for Private/NONE FREE stuff is always hard. What can you do Debian is FREE so you can not expect it to be as easy as Windows. But once you learn how to do it, in the future will be easier.

Now you are ready for 1rst OpenCL test.

Ok so Nvidia os dpoing Opencl. Nice,

Now that you have mesa tools you should be able to do
Code:
DRI_PRIME=1 glxinfo -B
DRI_PRIME=1 glxgears

And you should be able to track GPU status ( Temp & usage ) using

Code:
nvidia-smi

or

Code:
nvidia-smi --query-gpu=temperature.gpu,utilization.gpu,utilization.memory,memory.total,memory.free,memory.used --format=csv -l 5

or all
Code:
nvidia-smi --query-gpu=timestamp,name,pci.bus_id,driver_version,pstate,pcie.link.gen.max, \
pcie.link.gen.current,temperature.gpu,utilization.gpu,utilization.memory, \
memory.total,memory.free,memory.used --format=csv -l 5

As you have a laptop you want to watch GPU temperature while running Opencl. rember this is just for learning. NEVER rely used bruteforce in a laptop contimusly. You can overheat laptop tpo a point that it breaks PC!!
