@generix Hi, please have a look.

You have bound the nvidia gpu to vfio for passthrough.

@generix How can I undo that and fix the problem? Also, I don’t fully understand what you mentioned - Could you please explain?

??? This is not something that can accidentally happen. You set
on kernel cmdline to pass it though to a vm. Please remove.

@generix How can I do that via the terminal?


Thanks. I will give it a try and update the result here.

@generix The issue is now resolved. Thanks.
