Hi all

I am in trouble to setup an extra monitor for my laptop. I am using Opensuse Tumbleweed with KDE 5 Plasma. I have two graphic cards:
* An Intel card (onboard/default)
* A NVIDIA GeForce GTX Mobile Ti 1050 (I have installed the NVIDIA driver)

My xorg.conf is

Code: Select all

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 515.65.01


Section "ServerLayout"
     Identifier     "Layout0"

If I try use both screens (across many options and tries...), I experienced some types of problems:
* Entire X11 system doesn't work. It fallbacks to the text mode interface (wrong configuration or with Xinerama enabled)
* If I use "intel" as the primary screen: the other one is recognized as a black screen. Just that. I can move cursor on it, but i can't open windows or use it as a Desktop
* If I use "nvidia" as the primary screen: the other one isn't recognized. Just a "dead screen".

Can you help me? I accept instructions about to use Wayland too. Thanks
