(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!

When I installed it, I had some troubles making my NVIDIA GeForce GTX 860M 2GB works with hardware acceleration, etc, but at the end everything was OK. THIS WEEK (around 02/25/2015) an update destroyed this beautiful equilibrium: I can't resume after suspend and I can't plug or unplug my external monitor without having a weird problem: a) Desktop "moves" half of it size to the right. b) Mouse works, but I can't click on anything. The only workaround is killing the Xorg, and loosing the session. What I tried, without success: 1) Downgrade Compiz (the first suspect, it was upgraded this week). Nothing. 2) Install ALL possible NVIDIA drivers: 2.a) Nouveau 2.b) Nvidia 304 & Nvidia 304 updates (blacklisting and purging nouveau) 2.c) Nvidia 331 & Nvidia 331 updates (both from repository and NVidea website). (blacklisting and purging nouveau) 2.d) Nvidia 340 (from Xorg-edgers ppa). (blacklisting and purging nouveau) 2.e) In every case, I purged previous drivers before, reconfigure Xorg, etc, etc,etc. 3) Reinstalling Unity and Ubuntu-desktop I honestly don't know what else to do, but this situation it's very annoying. Any ideas? Please?
