LinuxQuestions.org - [SOLVED] How to disable Twinview in Ubuntu's nvidia drivers.

Hi.

I need Your help. Could You help me?

I have problem with TwinView with nVidia drivers on Ubuntu 12.04. I user 310.19 but this problem occurs on all nvidia drivers - exept nouveau.

It is related to recognizing more than one screen, and that is not right - i have only one.

It looks like on attached picture. When i boot to ubuntu destkop nvidia sees two screens and my picture is stretched to both of them. Some screen goes for "fake crt" (i don't have crt), and rest goes for my LCD flat screen (HP).

Is there a way to completly disable TwinView, prevent it from working, from detecting more than one screen when, in fact, i have only one?

I think that option in Xorg.conf "TwinView" "off" doesen't help:

Code:

firekage@deusex:~$ cat /etc/X11/xorg.conf

Maybe it is related to "metamodes" and the rest after it?

When i boot up, and when nvidia detects more than one screen, i have ti "fight" in order to disable it but after reboot the same thing happens. If im lucky, than i'm able to run terminal, and in it I run nvidia-settings (but it often runs in "crt fake screen" and i can't set up it because it is on far left "fake screen").

I added second picture - it shows how the screen is deformed when ubuntu/nvidia detects second screen, which i dont have!
