Bagaimana cara memasang kartu grafis kedua dan menggunakan 4 monitor?

Saya akhirnya memutuskan untuk mengambil jendela terjun dan parit. Setelah beberapa jam, saya dapat berfungsi dengan baik dengan semua aplikasi saya diinstal. Satu-satunya masalah adalah bahwa saya menjalankan 4 tampilan desktop dari 2 adapter nvidia, adaptor pertama (GeForce GT 240) dengan dua layar berfungsi dengan baik tetapi sepertinya tidak bisa mendapatkan adaptor kedua (GeForce GT 620) diinstal. Menggunakan Ubuntu 14.04 LTS (AMD64)

Tolong bantu saya dengan instruksi sederhana. Info terminal untuk diikuti:
