debian testing and bumblebee issue

[FateRover]

i used to use debian stretch and install bumblebee successfully,but when i compeletely new install debian testing and install bumblebee follwing "debian bumblebee wiki" :

Code: Select all

sudo dpkg --add-architecture i386 && sudo apt-get update && sudo apt-get install bumblebee-nvidia primus primus-libs:i386

and test is it working right by

Code: Select all

optirun glxgears -info

,it shows in terminal

Code: Select all

primus: fatal: failed to load any of the libraries: /usr/lib/x86_64-linux-gnu/nvidia/libGL.so.1:/usr/lib/i386-linux-gnu/nvidia/libGL.so.1:/usr/lib/nvidia/libGL.so.1
/usr/lib/x86_64-linux-gnu/nvidia/libGL.so.1: cannot open shared object file: No such file or directory
/usr/lib/i386-linux-gnu/nvidia/libGL.so.1: cannot open shared object file: No such file or directory
/usr/lib/nvidia/libGL.so.1: cannot open shared object file: No such file or directory

so did i make something wrong or just the wiki should be update?
