I have no idea which package you mean here.

 The primary screen works
 OK, the new, smaller one (DP-0, Monitor1) is the problem.  The primary
 is connected with a DVI cable, the second is connected with a DVI/RGB
 adapter.
 
 This is the xorg.conf:

[snip xorg.conf]

As suspected, it's the proprietary nvidia driver with the separate X 
screen setup (I'm using that too).

First I'd try messing with the DPMS settings with xset, but you 
mentioned the only way to re-activate the second screen was password in 
some screensaver (you still didn't mention the desktop environment), so 
I suspect the knobs you are looking for are in that area.

Kind regards,
Andrei

 I have now got the two monitors displaying a single screen and the
 mouse passes from one to the other.  However, the second screen
 blanks after around 20 seconds of non-use and nothing will bring it
 back to life.  I can pass the mouse into it, or select a  window
 that is on it, but it remains black.  The only exception is that it
 will restore when the screen is locked and I enter my password to
 unlock it.

Sounds like screensaver or similar. Based on your description I would 
guess you are using the separate screens setup, but more information 
about this, the driver and the desktop environment you are using would 
be necessary to help you.

Kind regards,
Andrei

Dual monitor problems

2013-06-24 Thread Oliver Elphick 
I am trying to use two monitors at once, for the first time, using an 
Nvidia dual head card.


I have now got the two monitors displaying a single screen and the mouse 
passes from one to the other.  However, the second screen blanks after 
around 20 seconds of non-use and nothing will bring it back to life.  I 
can pass the mouse into it, or select a  window that is on it, but it 
remains black.  The only exception is that it will restore when the 
screen is locked and I enter my password to unlock it.


Where should I look?

Debian version: sid, recently updated
