    Question How can I disable one screen for login ?

    I use Ubuntu Gnome 16.10 on a desktop PC with dual screen.

    I have an Nvidia graphic card (GTX 960 TI) and since I had a hardware problem, one of the outputs of the card doesn't work well.

    Since this problem, linux seems to detect a third screen, seen to be the main screen for login, so I have to log in a "blind" way (I can't see what I'm taping or doing).

    How can I configure the login screen to ignore this phantom screen and show the login options on my real main screen ?

    Here is a xrandr output for my system : https://paste.ubuntu.com/23677906/ (the DVI-I-0 seems to be the "phantom" screen).

    (And Merry Christmas to all !)

    I resolved my problem by changing my graphic card. No more ghost screen...

    Happy new year to all !
