    Default Monitor resolution lost

    I use a 1920x1080 monitor connecting through a VGA 9-pin plug, that needed a xorg.conf file until Leap 15.0:
    Code:
    Section "Monitor"   Identifier "Default Monitor"
      DisplaySize     305 230
      HorizSync       30-81
      ModelName       "SYNCMASTER BM1943/943TM SYNCMASTER MAGIC CX943B/CX943BM(DIGITAL)"
      Option          "Monitor-VGA" "VGA-display"
      Option          "PreferredMode" "1920x1080"
      VendorName      "SAMSUNG"
      VertRefresh     56-75
      ModeLine        "1920x1080"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync
    
    EndSection
    I installed Leap 15.1 new. In the first install display I selected resolution 1920x1080 with [F3] Video,
    and all proceeded with no more ado, keeping the correct resolution through several boot cycles.
    xorg.conf.d/50-monitor.conf was in its default state, no monitor data set.
    A few weeks afterwards, I disconnected the computer for maintenance (dusting). When I booted up,
    display resolution was down to default ; the best approximation Display settings proposes is 1600x900,
    and this does not cover the whole display, leaves vertical bars left and right (though not up nor down).

    Code:
    ~> xrandr
    Screen 0: minimum 8 x 8, current 1600 x 900, maximum 16384 x 16384
    DVI-I-0 connected primary 1600x900+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

    I would be very willing to solve this problem on my own, but I do not know where to find the proper documentation.
    All references I found are about the installation process.

    The pragmatic option might be to simply reinstate the Xorg configuration. Graphics hardware details might allow others to comment further perhaps...

    Code:
    inxi -Gxx
    openSUSE Leap 15.0; KDE Plasma 5

    Well, I'll do that lacking a real solution ; but since the "F3 : Video" option in the installation process works, I guess there is a way of settings things right. Shouldn't a piece of software manage such cases ?

    Inxi -Gxx only produces complete graphics info when in graphics mode, X or Wayland, in Xterm, Konsole, Gnome Terminal, etc. It will then report the complete driver configuration, as there is more than one driver involved in the entire system.

    What's wrong with the inxi -Gxx report quoted in my first post ? I copied it from a Gnome terminal in graphics mode.

    Code:
    hwinfo --monitor
    might be useful here as well. 1920x1080 in use formerly on a display that now permits only up to 1600x900 is quite uncommon. I don't think I've ever seen it before.

    About inxi - I've never tried it with sudo, as there's no need to that I've ever discovered, in part probably also to avoid that root out of X response. Also I never use Gnome*.

    * I'm new to Gnome, which I selected because I read a note during the installation process pointing at issues with kde+nvidia.

    hwinfo -- monitor returns nothing ; which does not surprise me, as I have always had to set its params manually.

    Post:
    Code:
    cat /var/log/Xorg.0.log
    Use susepaste for that:
    paste.opensuse.org

    Have you tried it without any conf-File?
    And using nvidia-settings as root?
