[SOLVED] xrandr can't detect other monitor

Hi,

Here is my problem, I try to make a dual sreen by myself just by editing Xorg .conf files. But I need to detect my second monitor first.
nvidia-setting detects my monitor but xrandr (-q) don't.

Here is the conf file of my monitor :

Section "Device"
    Identifier     "Default nvidia Device"
    Driver         "nvidia"
    Option "NoLogo" "TRUE"
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    Option         "DPMS"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection "Display"
        Depth          24
        Modes          "1280x800_75.00"
    EndSubSection
EndSection

Here is the xrandr -q result

agrum ~ $ xrandr -q
Screen 0: minimum 320 x 175, current 1280 x 800, maximum 1280 x 800
default connected 1280x800+0+0 0mm x 0mm
   1280x800       50.0* 
   1024x768       51.0     52.0  
   832x624        53.0  
   800x600        54.0     55.0     56.0     57.0     58.0  
   720x400        59.0  
   700x525        60.0  
   640x512        61.0     62.0  
   640x480        63.0     64.0     65.0     66.0     67.0  
   640x400        68.0  
   640x350        69.0  
   576x432        70.0  
   512x384        71.0     72.0     73.0     74.0     75.0  
   416x312        76.0  
   400x300        77.0     78.0     79.0     80.0     81.0  
   360x200        82.0  
   320x240        83.0     84.0     85.0     86.0  
   320x200        87.0  
   320x175        88.0

Since nvidia can make a dual screen with my current configuration, I don't think I have to edit it. But I would like to knwo how to detect my second monitor, get its name, if its a VGA, DVI, CRT ...

Thanks.

Unfortunately the nvidia drivers do not support randr.  It is a real pain in the backside.  The last time nvidia-settings would not detect my monitor was due to using a realy old VGA cable.

I finally found an issue.
I don't need nvidia-setting and xrandr anymore.
I will put my config file later if you ask for it.

Re: [SOLVED] xrandr can't detect other monitor

@wangcutopen, this thread is half a year old. I suggest you use nvidia-settings to do your setup for your nvidia card. Search the wiki for 'nvidia', or go to nvidia's linux forum. Try google after that.

If all those steps don't work, then open a new forum thread. But only after trying all those.

EDIT: re-opening, misread the dates on the post. My bad.
