I have Linux Mint 13 64 bit version with cinnamon, NVdia Geforce 320m, proprietary driver 304.54 if I'm not mistaken. I installed bumblebee following this guide:
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia linux-headers-generic
Rebooted, and now I have 640x480 resolution, half-broken gnome 3 was loaded (there are no buttons to log out or reboot, no animations of course). When I try to run nvidia-settings I get:
You do not appear to be using the NVIDIA X driver.
Please edit your X configuration file (just run `nvidia-xconfig` as root),
and restart the X server.
What shall I do to fix this? I want my discrete graphics card and cinnamon back.
