Hello, I am new to linux, and I just want to make sure if I use my Nvidia GPU (my laptop have intel gpu and nvidia gpu) at this moment, I found nvidia_smi command which should show data about it, but I am not fully sure because of this line: 0 NVIDIA GeForce ... Off | 00000000:01:00.0 Off.
Those “Off”-s confuse me, what those “Off”-s mean?
Output of nvidia-smi command:

I actually have no idea what Off means there,but the way to know if you are using the nvidia card is if the process appears there,for example,Dolphin Emulator when using nvidia card appears like this
nvidia-smi

Thanks, yeah this is solution. Apparently I searched about this topic more and found detailed info about this output here: https://medium.com/analytics-vidhya/explained-output-of-nvidia-smi-utility-fc4fbee3b124 yeah I am stupid, but maybe this topic will be useful for somebody
If you have a laptop with intergrated graphics and a dedicated nvidia gpu and want to make certain that a program is running on the nvidia card launch it with the “prime-run” command. For example prime-run steam will launch steam on the nvidia card. I have read that the latest nvidia drivers don’t need the prime-run command but I still use it
