How do I create the prime-run command? sorry, still a beginner in Linux. I need a detailed tutorial
You have not answered this one:
You have a typo. Simply copy Sauerlands commandā¦
I think @Sauerland is wants to know what hardware you are using. From my laptop that has both intel and nvidia graphics (optimus)
ox@nanus$ lspci -nnk | grep -EiA3 'vga|display|3d'
00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 530 [8086:191b] (rev 06)
Subsystem: ASUSTeK Computer Inc. Device [1043:1130]

You can right click copy / right click paste to put the command output here ā¦ much easier that taking photos

There should be someplace in KDE settings that will tell you whether you are running KDE on X11 or wayland. It should also tell you which gpu is being used to render graphics. I donāt use KDE, so I canāt give specific instructions.
What is the output of nvidia-smi?
# nvidia-smi

Great!
You donāt have to do anything with prime-run or offload. Your entire environment is using the nvidia gpu.
If you want to make your battery last longer, you can switch to the intel graphics by typing āsudo prime-select intelā. Then you must log out and log back in.
When running the environment on intel, you can run a specific application on the nvidia gpu by using āprime-run APP_NAMEā. An easy way to test that it is working correctly is āprime-run glxgearsā and then nvidia-smi from another terminal window.
prime-run is not available on my laptop mr. on this website it is explained that I was told to make it myself, but I donāt know because Iām still cloudy and the tutorial is too concise, lacking in details.
This page is describing something a bit more complicated than you need for right now. It is about setting up specific apps to always use the nvidia gpu.
/usr/bin/prime-run is in the package āsuse-primeā, which should have automatically installed with the nvidia drivers.
leap diversion 15.6 prime-run not yet available, must be configured / created manually.
Did you read the wiki and which system the TO is using? The TO is using Leap 15.6 and suse-prime for Leap does not contain the prime-run script. It is only available for Tumbleweed as it uses a newer suse-prime version. So for Leap you need to create the prime-run script yourself with the content mentioned in the SDB.
can you help me with a detailed and easy to understand tutorial? Iām still a layman, and Iām confused about following whatās in SDB
Create a file in your user directory (it is in your $PATH):
echo > /home/<yourusernamehere>/.local/bin/prime-run
Make it executable (for all users):
chmod 755 /home/<yourusernamehere>/.local/bin/prime-run
Open the file with a text editor like Kate and paste the lines mentioned in the SDB into the file. Save.
#!/bin/bash
__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia "$@"
Now you can offload single applications by starting the app with the prime-run script ala prime-run steam
Thank you to all of you
