(Sorry, the message was sent unintentionally) Thank you Brian. I removed all the suspicious PPAs using ppa-purge (sudo apt-get install ppa-purge)
sudo add-apt-repository ppa:xorg-edgers/ppa (just in case you had disabled the ppa before( sudo apt-get update (idem) sudo ppa-purge ppa:xorg-edgers/ppa sudo add-apt-repository --remove ppa:xorg-edgers/ppa (I don't remember if this is necessary or if ppa-purge already does this) the same with ppa ppa:bumblebee/stable then sudo apt-get purge xserver-xorg* sudo apt-get purge nvidia* then sudo apt-get install nvidia-331 sudo reboot after reboot, not only everything works perfectly (plugin or unplugging the external monitor, suspending, etc) but the hardware graphic acceleration is faster than ever!
