[Solved] - nvidia driver and docking station?

I have a lenovo T410 and a mini-dock docking station.

When I boot and connected to the docking station, the boot dialogues appear on my external monitor as they should. As soon as the nvidia driver loads, I only get video on my laptop.

I'm sure it's a nvidia configuration issue. Would anyone be able to point me to an article or a post on setting this up? I looked in the wiki and didn't find anything. I also didn't see anything under the nvidia driver in the wiki, for using docking stations.

Thank you for reading and any help will be greatly appreciated.

Re: [Solved] - nvidia driver and docking station?

I suspect you are using the proprietary driver. In this case you can use the nvidia-settings utility to disable the internal LCD and enable the external monitor. It is save to store the settings in /etc/X11/xorg.conf also if you do not have your laptop docked. In this case the settings in xorg.conf are overridden and the output is directed to the internal display.

My config as an example (DFP-2 is the DVI-port on the dock, this may differ to yours):

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Hewlett Packard"
    ModelName      "HP LP2475w"
    HorizSync       30.0 - 94.0
    VertRefresh     48.0 - 85.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "NVS 3100M"
    Option         "NoLogo" "true"
    Option         "RegistryDwords" "EnableBrightnessControl=1"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "0"
    Option         "metamodes" "DFP-2: nvidia-auto-select +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Re: [Solved] - nvidia driver and docking station?

Solved - thank you very much.

I had to adjust my xorg.conf file with:

Option     "TwinView"     "1"

Then rebooted, and started nvidia-settings utility. The external monitor appeared.

I went ahead disabled the monitor on my laptop. Rebooted.

Set external monitor's position = absolute,

Enabled laptop monitor. Set positiion = right of.

Adjusted kde power setting, so when it's plugged in/docked and lid closed it turns the screen off.

Everything worked as it should

The picture is a bit fuzzy, but I am sure I can probably fix this after I play around with the nvidia driver for a bit.

Thanks again for responding. I'm definately going to compare you xorg.conf settings to mine, to see if I can get my picture right.
