I configure xorg.conf for the laptop screen only and use nvidia-setting to
setup twinview mode for the external screen (it does not require to restart
X). It works fine so far.
Hope this help

Hi all,<br>
<br>
For a long time I've been using nvidia's twinview for two 1920x1200=
<br>
displays (laptop and external LCD).<br>
<br>
Whenever I dock / undock I have to run nvidia-settings to change the<br>
resolution from the virtual 3840x1200 to 1920x1200 or vice versa. =C2=A0Als=
o<br>
since two screens is the "Default" I have to do this when I log i=
n with<br>
only the laptop.<br>
<br>
I am looking for a way to use the command line nvidia-settings (as much<br>
as I've studied the help I can't find out how to do it - all attrib=
utes<br>
seem read-only to the command line nvidia-settings)<br>
<br>
Then I can call nvidia-settings --some-options on a dock / undock event.<br=
>
<br>
Alternatively, I read in the nvidia-drivers README that you can use<br>
metamodes and then use the FN-F8 (CRT/LCD switch key) to switch between<br>
them. =C2=A0However, when I use metamodes I always get a 3840 wide screen,<=
br>
and I can "scroll" left and right to the unseen space.<br>
<br>
These are the metamodes I've tried:<br>
1. The two-screen only metamode:<br>
=C2=A0 =C2=A0Option =C2=A0 =C2=A0 =C2=A0 =C2=A0 "metamodes" &quo=
t;DFP-0: 1920x1200 +1920+0, DFP-2: 1920x1200 +0+0"<br>
2. attempt to use a 1920 metamode as well:<br>
=C2=A0 =C2=A0Option =C2=A0 =C2=A0 =C2=A0 =C2=A0 "metamodes" &quo=
t;DFP-0: 1920x1200; DFP-0: 1920x1200 +1920+0, DFP-2: 1920x1200 +0+0"<b=
r>
3. attempt 2:<br>
=C2=A0 =C2=A0Option =C2=A0 =C2=A0 =C2=A0 =C2=A0 "metamodes" &quo=
t;DFP-0: 1920x1200 +1920+0, DFP-2: 1920x1200 +0+0; DFP-0: 1920x1200 +0+0,&q=
uot;<br>

Here's my screen section (all other sections are basic):<br>

Has anyone done a dynamic mode change with nvidia xinerama?<br>
