[SOLVED] 2nd monitor has black screen, please help to configure the xorg.conf
« on: June 18, 2012, 10:56:26 PM »
Hello,

I ran the NVIDIA Display Settings, it did not allowed to save the changes but I was able to see the configurations, so I went with RootPCMan and changed the file etc/X11/xorg.conf

1.- Original xorg.conf
Code: [Select]

2.1 I have the second monitor, Monitor 1 (AOC 2043),  totally black and when I move the mouse from the Monitor 0 (AOC 2343) to the second one the cursor changes from black arrow to a white X and the mouse moves from Monitor 0 to Monitor 1, that is an improvement, now the second monitor is recognized but it is totally black. Fortunately Monitor 0 works fine.

2.2 After changing the xorg.conf the NVIDIA GPU temperature jumped from 43 Celsius, green zone,  to 53 Celsius and entered into the yellow zone.

3.- Can someone please help me to correct my mistake so I can have video in Monitor 1, and decrease the GPU temperature?

Thanks and regards

I believe you are missing the UseEDID options in the Monitor sections. What I'm referring to is shown in brown below.

Section "Monitor"
    # HorizSync source: edid, VertRefresh source: edid
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "AOC 2343"
    HorizSync       30.0 - 83.0
    VertRefresh     55.0 - 75.0
    Option         "DPMS"   
    Option         "UseEDID" "TRUE"
    Option         "UseEDIDFreqs" "TRUE"
    Option         "UseEDIDDpi" "TRUE"

EndSection

Section "Monitor"
    # HorizSync source: edid, VertRefresh source: edid
    Identifier     "Monitor1"
    VendorName     "Unknown"
    ModelName      "AOC 2043"
    HorizSync       30.0 - 81.0
    VertRefresh     55.0 - 75.0

    Option         "UseEDID" "TRUE"
    Option         "UseEDIDFreqs" "TRUE"
    Option         "UseEDIDDpi" "TRUE"
EndSection

You may be missing something in the "ServerFlags" section. Maybe Option "Xinerama" "0". I'm not really sure.

Thanks djohnston

1.- The additional options on the Monitor section did not work.

2.- But I activated Xinerama and it worked.

This is the final etc/X11/xorg.conf

3.- I still have the issue of the GPU temperature in the yellow zone 54-55C, but as per nvidia forum it is normal with 2 monitors.
3.1 Also the colors do not look exactly the same even they both are AOC Flat panel with same DCR, no matter how I configure the color temperature, brightness and contrast.

Anyway, finally now is working like I want, so I can have my Kanban board in one of the monitors.

Best regards
