2 monitors on Karmic Koala 64

February 4th, 2010 Leave a comment Go to comments

In December I bought this brand new laptop and had the perfect excuse to upgrade to Ubuntu 9.10. Like I mentioned in this post, the video drivers were the only issue I had.

Nvidia released new drivers for Linux 64 (v. 190.53) so I took the chance to update and plug an old 19” monitor to my laptop. To enable TwinView I muddled through some documentation but finally made it work.

Here’s the code from xorg.conf that enables TwinView:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection
 
Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option	    "TwinView"
    Option	    "ConnectedMonitor" "DFP-0, CRT-0"
    Option	    "MetaModes" "DFP-0: nvidia-auto-select, CRT-0: nvidia-auto-select"
    Option	    "CustomEDID" "DFP-0:/path/edid/monitor1.bin; CRT-0:/path/edid/monitor2.bin"
    Option	    "TwinViewXineramaInfoOrder" "DFP-0,CRT-0"
    Option	    "TwinViewOrientation" "DFP-0 LeftOf CRT-0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

I had to add the binary EDID files because the X server was unable to identify the correct resolution for my laptop: 1366×768. The second monitor is 1280×1024… now I’m really seduced by a 27” monitor.
