Bumblebee doesn't work?

i installed bumblebee in ubuntu mate 16.04 LTS
$sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic
and when i tried to run $optirun firefox it gave me the following output :

[ 916.390458] [ERROR]Cannot access secondary GPU - error: [XORG] (EE)

[ 916.390513] [ERROR]Aborting because fallback start is disabled.

so,any solution for that.

See the post below titled “Bumblebee not working after upgrade to 16.04” for a fix.
