NVidia: internal/external display switching

[Dmitry Kasatkin]

Hi,

The problem seems that I use 2 monitors - DVI (DFP-1) and VGA (CRT-0) at
the same time in Twin Mode.
If I add also to use internal LCD then I see in xorg.log that it says
only 2 simultaneously supported.
And it somehow disables internal DFP-0.
And then when resume without dock then X will not use DFP-0 anymore.
If I kill X with Ctrl-Alt-backspace then it will start using DFP-0 since
DFP-1 and CRT-0 is not available.

But if I do not use vga then I can configure twin view "clone" mode and
X will use DFP-0 and DFP-1. Then in this case after resume it will use
DFP-o or 1.


- Thanks

Hi

Just cloning the screen is no solution?
