    Re: Nvidia card/driver and 2560x1440 Monitor

    Well, I think it's not necesary to start another thread, it seems the problem I'm going to explain maybe related to this Xorg.conf.

    Ok, so I have finally the multy monitor set up nice and today I bought several linux games at steam.
    I'm trying some games and everything seems to work, until I check killing floor, (others like FTL and PENUMBRA failed too, so its not a specific game issue), the game starts and the X screen crashes. I see the blue light from the shimian monitor blinking and I have to restart the X server to come back to life.

    Windowed mode in these games works. First I'm trying to solve here is what the problem is
    Scalating? Xorg.conf? OpenGL?

    Are you experiencing the same issues?

    EDIT: Well, everything is a little messed up, first of all, I managed to make some games work by manually adding to the .ini and .cong files the monitor resolution. Unfortunately, It's not possible (or I can't) to use this solution with all games/software. I.e. opening XBMC directly kills the Shimian monitor and arrange the layout telling me there is only the 190x1080 monitor, and so on...
    How can I make my xorg.conf to eork properly?

    THANK YOU OP - you are a life saver!
    Just to help anyone who reads this this xorg.conf worked for 1 catleap monitor and a gtx 670:
    Code:
    Section "Monitor"
        Identifier     "Monitor0"
        VendorName     "Shimian"
        ModelName      "QHD270"

        VertRefresh    59.5
        Option         "DPMS"
        Modeline       "2560x1440" 241.50  2560 2608 2640 2720  1440 1443 1448 1481 +hsync -vsync
        DisplaySize    597 336
    EndSection
    
    
    Section "Device"
        Identifier     "Device0"
        Driver         "nvidia"
        VendorName     "NVIDIA Corporation"
        BoardName      "GeForce GTX 670"
    EndSection
    
    
    Section "Screen"
        Identifier     "Screen0"
        Device         "Device0"
        Monitor        "Monitor0"
        DefaultDepth    24
        Option         "NoLogo" "True"
        Option         "UseEDID" "False"
        Option         "UseEDIDDPI" "False"
        Option         "UseEDIDFreqs" "False"
        Option         "ExactModeTimingsDVI" "True"
        Option         "metamodes" "2560x1440_60 +0 +0"
        SubSection     "Display"
            Depth       24
        EndSubSection
    EndSection
    
    
    Section "ServerLayout"
        Identifier     "Layout0"
        Screen      0  "Screen0" 0 0
        Option         "Xinerama" "0"
    EndSection
    Just a tip, if you can't even get to a tty shell (for example my monitor turned off if I tried to) then just put the file on a usb, boot into grub > recover mode > fsck > root
    now you have a console and simply move the file to /etc/X11/xorg.conf

    Again, awesome work for figuring this out

    My particular model is QNIX QX2710

    When I got it was not working but I've fixed with "modeline". There's a lot of info on this.

    However when I upgrade to kubuntu 13.04 raring the 'kde plasma workspace' stopped working. I.e. lightkdm showed it's login screen but when I hit Enter after few secs the monitor starts flickering (red,blue,green then stripes etc).

    After spending couple of hours (playing with edid etc) finally I've easy workaround:

    Just when you enter login/pass and hit Enter switch termorary to terminal with Ctrl-Alt-F1, wait few secs till it boots and then switch back with Alt+7.

    While this workaround is required for KDE GNOME (as in Ubuntu session) worked fine.

    Anyone got this running past 60Hz? I can't get it to work with anything but the 60hz modeline from cvt

    I run this using Thinkpad x220 and PH4E eGPU card with GF 8800 GTS attached. Everything is pretty smooth. No lags or hangouts. Now looking for a way to make it tripple head.
    The only noticed problem is lag while scrolling extreamly heavy pages (mostily forums) in Firefox.

    Re: Nvidia card/driver and 2560x1440 Monitor

    Running Ubuntu 13.04, with Nvidia's 325 drivers via xorg-edgers. After finally getting the drivers to work without bricking the whole install, it turned out I was still limited to 1024x768 because of my Catleap. Fixing the xorg.conf like you've described in this thread actually helped, but now I'm limited to 1600x1200 instead. =/ I've tried several of xorg.conf posted here, but can't make any progress.
    Does anyone know how to fix my problem?

    Re: Nvidia card/driver and 2560x1440 Monitor

    Hi All,

    I wanted to thank the op for this. I was having a killer time getting my Korean Crossover 27QW to work with ubuntu nvidia 331.20 drivers I installed( for anyone having issues installing the nvidia driver for ubuntu 13.10. Use this repo http://www.ubuntuupdates.org/ppa/ubuntu-x-swat with this guide http://news.softpedia.com/news/How-t...0-399182.shtml, I tried a million ways and this was the only one that worked. The edgers ppa doesn't work.

    After I ran sudo nvidia-config. Then sudo nvidia settings. Used the assigned names to make changes in the xorg file. Here is my xorg. My major change to get me smasung 27" monitor to work was to enable the "UseEDID" If I set it to false, then my samsung monitor wasn't detected. Maybe this will help someone else. So just delete all the EDID false options and your second monitor should be detected.
