Debian 8 Nvidia Установка с Bumbleebee не активна

я добавил /etc/apt/sources.list

deb http://ftp.tu-graz.ac.at/mirror/debian/ jessie main non-free contrib
deb-src http://ftp.tu-graz.ac.at/mirror/debian/ jessie main non-free contrib
deb http://ftp.tu-graz.ac.at/mirror/debian/ jessie-updates main contrib non-free
deb-src http://ftp.tu-graz.ac.at/mirror/debian/ jessie-updates main contrib non-free

После

apt-get update
apt-get install bumblebee bumblebee-nvidia primus
usermod -a -G bumblebee myuser

После перезагрузки

root@pc:/home/pc# lspci  | grep -i VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
01:00.0 VGA compatible controller: NVIDIA Corporation GT218M [GeForce 310M] (rev ff)

И когда я установил этот код
