A little note about gnome 3 (I’m not the first nor will be the last!).
Gnome 3 is an environment discovered since its launch, I had no a priori not knowing previously v2.
Then I discovered via the Calculate CLDG: very well put together, a setting graphic for my taste (bravo devs’
).
But the transition from 3.4 to 3.6 is a disaster! All my settings (including my shortcuts) are erased ! and those of my computers. I tried punctually adventure cinnamon to be less constrained: idem.
What to do? Gnome 2: for what future? Mate?
Thank you for listening to me dear friends, it is cheaper than a session with a psychologist 
Sincerely,
PS: your reactions …
