On Ubuntu,when I set background option true, the miner will not work！

[YourWildDad]

On Ubuntu server 16.04, I compiled xmrig with CUDA9.
when the background option is false. everythings is well.
but when the backgroud option is true, the miner looks like working, but speed always is n/a.
when I run the xmrig-nvidia ,my console output some result like:

root@server91:/tmp# xmrig-nvidia 
root@server91:/tmp# 
GPU 0: initialization error
cuda_get_deviceinfo line 302
Setup failed for GPU 0. Exitting.

I also set the log-file option, the log looks like this:

How can i make this program run in background?
Thank you.

xmrig-nvidia -B -l log-file-name -o stratum_url -u wallet_address -p x 2>&1 1> /dev/null

Notice in the last portion I added 2>&1 1> /dev/null - this will run the code in the background thus keeping all the logs on the log-file-name specified
