I tried to install bumblebee because of a HDMI problem. I ran these commands:
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia virtualgl linux-headers-generic
sudo reboot
Then I got The system is running in low-graphics mode
, and I couldn't solve it.
Here are some outputs;
$ dpkg -l | egrep "nvidia|bumblebee"
