          So i found that ubuntu 14.04 LTS changed to Unity 3D instead of Unity 2D and that it “pushes” the graphical chip into a 3D-modus and because of that i can only have anymore a resloution of 2048 x 2048 wich is not enough if i want to use a second screen.. I found some scripts to change this like for instance 3048 x …. but this didn’t do anything… So i found i should install this gnome version.. But this doesn’t go either…. cause i have this if i run it…

              @Nele – Try these options and let know.

              Option1:

              Run the command : sudo apt-get update
              Then run your command: sudo apt-get install gnome-session-flashback

              See if it works.

              Option 2:
              Directly launch Ubuntu Software Center to install. Click below link, it will directly launch. Wait for couple of seconds.

              apt://gnome-session-fallback

                Hi thanks a lot, for your help! I tried option 1 a lot ( and also some modified commands of it) but that didn’t work…. At the end, I just de-installed Ubuntu and I installed Xubuntu and the problem was directly solved! Thanks anyway!
