Cloning display not working on laptop

English Hardware
#1

Hi All,

I am having trouble getting my Dell M6400 laptop display to be cloned with the Hyundai LCD display I have connected to my docking station.

I have an Nvidia Quadro FX 2700M graphics card and have installed the proprietary driver according to SDB:NVIDIA drivers - openSUSE. I have tried using sax2 (found out today it is depreciated so will stop that) and running nvidia-xconfig from both init 3 and init 5 followed by nvidia-settings to setup cloning mode.

When I run nvidia-settings, it doesn’t detect the laptop display it seems. It says the max resolution is 640x480 even though the max is 1920x1200 and this does get used if I boot the laptop without a monitor attached.

Also, when I try and select cloning nvidia-settings crashes with a segmentation fault.

What can I do to get this working?

Many thanks for your help,

openSUSE 11.2.
Linux 2.6.31.12-0.2-desktop #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux

I am having trouble getting my Dell M6400 laptop display to be cloned with the Hyundai LCD display I have connected to my docking station.

Are you able to connect the LCD display directly to your laptop ok?

I have tried using sax2 (found out today it is depreciated so will stop that) and running nvidia-xconfig from both init 3 and init 5 followed by nvidia-settings to setup cloning mode.

So, I’m assuming that you now have a valid /etc/X11/xorg.conf file present (even if display resolutions are not yet correct). If so, can you post the contents of this file?

When I run nvidia-settings, it doesn’t detect the laptop display it seems. It says the max resolution is 640x480 even though the max is 1920x1200 and this does get used if I boot the laptop without a monitor attached.

IIRC, I think is a known bug that occurs when an external display is connected on a VGA port with nvidia chipsets. You might have to manually tweak xorg.conf to get around this.

Another portential issue is display devices that don’t cooperate with correct EDID info, causing the X-server to use the wrong display mode. More on this here:

Hopefully, this will help you to get a working xorg.conf for your situation. :slight_smile:

When I run nvidia-settings, it doesn’t detect the laptop display it seems. It says the max resolution is 640x480 even though the max is 1920x1200 and this does get used if I boot the laptop without a monitor attached.

Also, when I try and select cloning nvidia-settings crashes with a segmentation fault.

It may be worth trying the option

Option "DynamicTwinView" "true"

in your xorg.conf, and try using nvidia-settings utility again. FWIW, a Dell twinview config with this option here:

http://en.gentoo-wiki.com/wiki/Dell_Latitude_D620

Since you only want cloning, have you tried removing xorg.conf

mv /etc/X11/xorg.conf xorg.bak

and restarting the X-server? AFAIU, both display devices should be detected and clone mode started by default.

OK - can clone and use both monitor and LCD now. Here is what I had to do:

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.moved
init 3
nvidia-xconfig
init 5
nvidia-settings
Configure the displays as desired.

I was able to apply and save the config without problems after that. I think the issue was that I was running the nvidia tools with an existing xorg.conf from whatever is shipped with openSUSE and the nvidia tools were merging with it. The key was probably to allow nvidia to start from scratch.

Many thanks for your help!

Glad to have been of help. :slight_smile:
