Although I am able to effect all kinds of other changes to my display setup as non-root, I'll try running it as root before changing the line Jim suggested.

Aside from Jim's advice, are you running the tool as root?<br>

I currently have two 23" monitors on my Wheezy desktop box. Now I've added a second video card (identical to the first) so that I can have a third and maybe a fourth monitor if needed. I installed the Nvidia drivers using these instructions:<br>
<br>
<a href="https://wiki.debian.org/NvidiaGraphicsDrivers" target="_blank">https://wiki.debian.org/<u></u>NvidiaGraphicsDrivers</a><br>
<br>
If I use the Nvidia GUI tool to enable the third monitor, it seems to work, and even changes the xorg file, but the settings don't stick and the file reverts to dual monitor on a single card.<br>

However, the third monitor never displays anything even though it's clearly being detected. I've tried both outputs on the new card. If I exit our of the Nvidia tool, the settings are not saved and next time I open it I have to detect the monitor again. I've tried with and without xinerama.<br>
<br>
Any ideas?<br>
<br>
cheers<br>
