Comment installer une deuxième carte graphique et utiliser 4 moniteurs?

J'ai finalement décidé de franchir le pas et de creuser les fenêtres. Après plusieurs heures, j'ai parfaitement fonctionné avec toutes mes applications installées. Le seul problème est que j'exécute 4 écrans de bureau avec 2 adaptateurs nvidia, le premier adaptateur (GeForce GT 240) avec deux écrans fonctionne parfaitement mais ne semble pas installer le deuxième adaptateur (GeForce GT 620). Utilisation d'Ubuntu 14.04 LTS (AMD64)

Veuillez m'aider avec des instructions simples s'il vous plaît. Informations sur le terminal à suivre:

Il est difficile que j'utilise quatre moniteurs sur Linux Mint 64, c'est le mien /etc/X11/xorg.conf.

Utilisation également du pilote binaire recommandé d'Ubuntu0.0.4 nvidia-331 .113

Peut-être que cela aidera, car c'était la chose la plus difficile à obtenir
