Creating xorg.conf file to support dual monitors

English Hardware
1

Hi,

I’ve been trying to configure my second monitor to work correctly. I’ve tried many things in the last couple of weeks (including the wiki) but nothing worked. Today I tried installing the driver which I got directly from nvidia’s website, and the second monitor worked for the first time!
However, ONLY the second monitor worked. The laptop’s screen did not work after the installing driver.
I figured out the issue could be the xorg.conf file that the installation created, since I’m pretty sure I didn’t have that before. The created file has the following:


# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 430.09

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

Section "Files"
EndSection

Section "InputDevice"
    # generated from data in "/etc/sysconfig/mouse"
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "IMPS/2"
    Option         "Device" "/dev/input/mice"
    Option         "Emulate3Buttons" "yes"
    Option         "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Keyboard0"
    Driver         "kbd"
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    Option         "DPMS"
EndSection

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

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

When I remove that file and restart, the laptop screen works, but the second monitor doesn’t.
I’ve searched around a lot and tried quite a few config files, but nothing works correctly.

Please note that I’m not 100% sure that only the xorg.conf file is to blame! I might’ve missed something.

My graphics card is NVIDIA GTX1650, and the processor is intel.

Any help would be very appreciated :slight_smile:

p.s. I’m sorry for the lack of information, but I don’t know what would be useful in this context.

Hi and welcome to the Forum :slight_smile:
If it’s a laptop, I suspect you have dual graphics, which requires additional tweaking with suse-prime…

Can you post the output from;


/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"
xrandr --listproviders
xrandr --listmonitors
3

Here they are:

Hi
Have a read here since your on Leap 15.1;
https://en.opensuse.org/SDB:NVIDIA_Bumblebee

But I would suggest using SUSE_Prime (available on Leap 15.1) instead as Bumblebee is somewhat deprecated going forward;
https://en.opensuse.org/SDB:NVIDIA_SUSE_Prime

OH MY GOD! Solved!
I’ve tried Bumblebee like 10 times, with slightly different steps and configs each time, and it always corrupts many things and I had to roll back to a previous snapshot.

Installing SUSE_Prime works like a charm!

Many thanks!:slight_smile:
