  2. No, you don’t have enough memory available: 2gb (desktop junk) + 4.3gb (DAG) > 6gb (total GPU memory)

    That Nvidia-smi output is clearly after the miner stopped, so it’s only telling you what your memory usage is at idle.

    I see you’re on a laptop, so that GPU is going to be your primary/only display adapter, right? And the desktop environment is going up take up some video memory, that’s what you’re seeing there (~2gb). You need at least 4.3gb free to start mining and you don’t have it.

    Not 100% sure if the nuances of GPU memory management in Ubuntu, but if that ~2gb usage is as low as you can get in normal usage, you might have to start up without the GUI for mining to ensure you have enough free memory.

    There are a few ways to do that:
