Dual monitor support?

Hi,

I'm trying to get dual monitor working. I added nvidia and ATI drivers. My current test notebook has a nvidia card and the driver is loading on boot and does find both monitors (display and external monitor). But when I try to activate it using xrandr it doesn't work.

Does someone know how to get this working?

Re: Dual monitor support?

whats about a correct xorg.conf

Re: Dual monitor support?

I thought it is autodetected like for example ubuntu does it. A hard coded xorg.conf is a problem for me because this setup should work with different monitor models and resolutions.

What I want is, that SliTaz starts up and automatically switches all connected monitors on with there optimal resolution. With ubuntu this works out of the box. Is there a way to do this in SliTaz?

I wanted to do it with xrandr but xrandr doesn't recognize all monitors for some reason. I read it is not dependent to xorg.conf.

Re: Dual monitor support?

you can try this

http://forum.slitaz.org/topic/xrandr-not-detecting-2nd-monitor#post-25620

and with xrandr I cant help - I never used it - perhaps just tell which version you are using 4.0 or rolling? - its more easy to answer

Re: Dual monitor support?

Thank you!

I switched to nv open source driver and xrandr does now find both monitors - LVDS and VGA. SliTaz has automatically activated the external monitor on VGA.

But I cannot activate LVDS, because it has no modes. The nv drver says: Not using mode "1440x900" (exceeds panel dimensions)

I do some research and try to get this working but now there must be a way

Re: Dual monitor support?

Really annoying. If I use nv driver, the graphics card in my Notebook works. If I use the nvidia driver, the driver in our Dell PC works. But I've found no solution to get everything working.

I'm thinking about using our old and big Ubuntu 12.04 to get this working... but this would not work with diskless clients.

Re: Dual monitor support?

but perhaps you can use the big and old Ubuntu to see how it works and try to redo this with SliTaz - I do it normally like this

Re: Dual monitor support?

But where should I look for it? On another Client with Ubuntu 12.04 I looked in /etc/X11 and there is no xorg.conf. It just works and I can't see how.

Re: Dual monitor support?

OK, I got it fully working for nvidia on one PC. Will try it on other machines tomorrow.

These are the relevant parts from xorg.conf (I hope so):

[c]Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

# perhaps totally irrelevant
Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "FUS P19-2"
    HorizSync       30.0 - 82.0
    VertRefresh     56.0 - 76.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Device"
    Identifier     "Videocard0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce FX 5200"
EndSection

# here it gets interesting!
Section "Screen"
    Identifier     "Screen0"
    Device         "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "CRT-0"
    Option         "TwinViewOrientation" "CRT LeftOf DFP"
    Option         "metamodes" "CRT: 1920x1200,1680x1050,1280x1024, DFP: 1920x1200,1680x1050,1280x1024"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection
TwinView[/c]

Re: Dual monitor support?

I see the Nvidia tool spits out CRT-0 and DFP-0 as your device names. Maybe the driver changes those and you could try running xrandr with those options instead?

Cheers.
