<div class="moz-cite-prefix">A caveat, we don't have any Linux
systems with NVIDIA graphics and two screens right now, so this is
generic advice. <br>
<br>
Also, I have a bias against laptops that have business graphics,
like the NVIDIA NGS4200, but it should still work. And I have a
bias against using a server Linux, like CentOS 6.5, instead of a
desktop Linux, like Ubuntu for 3D graphics -- the X server in the
desktop Linux distributions is better than the one in the server
distributions and the graphics drivers take advantage of that
fact.<br>
<br>
So my first recommendation would be to switch to Ubuntu 14.10 and
install the proprietary NVIDIA graphics driver from the Ubuntu
repository. If you want to stick with CentOS, then I'd recommend
upgrading to version 6.6 or even better version 7, but even if you
stick with 6.5, you should the latest NVIDIA driver from
nvidia.com.<br>
<br>
Then, use the nvidia-settings program to set the display
configuration. If nvidia-settings doesn't do what you need, then
read the extensive release notes for the NVIDIA driver (typically
in /usr/share/nvidia*/html/index.html) and edit the X
configuration manually. <br>

<br>
I'm writing to get your expert advice on the following: I have a
laptop with Nvidia NGS4200 card docked into a docking a station
with an extra monitor connected. Under Windows (XP or W7) and
Mandriva linux there is no problem synchronizing the laptop and
the external monitors whether it's for Chimera or anything else.
However, I can't find the trick to do so under Centos 6.5 (I
switched to this system for several reasons). I tried the xrandr
command but does not provide a complete
synchronization/duplication. Do you have any advice on what I
should do to get it right?<br>
<br>
I would be most grateful.<br>
<br>
Cheers,<br>
