I get the logs -
| Code: | Oh no! Something has gone wrong.
A problem has occurred and the system can't recover. Please log out and try again. |
I get this after installing lightdm (over gdm), xfce (already had gnome) and installing the nvidia drivers. Rebooting after that gave me this error.
What could have gone wrong?

My GPU in case it is relevant - Nvidia GTX 1070 Max Q.
I get the white screen now after trying to login via lightdm. (I made lightdm my default login manager after solving the issue of the broken gdm)
I already had x11-drivers/nvidia-drivers emerged -> The nvidia driver version is 415.18.
zgrep "CONFIG_MODULES=" /proc/config.gz returned CONFIG_MODULES=y so it should be okay till now.
Created file nvidia.conf in /etc/modules-load.d/ with nvidia in it.
I have a systemd system -> I tried 'systemctl enable systemd-modules-load.service' but got the error 'The unit files have no installation config'.
I rebooted my computer. Before logging in and getting the white screen I tried 'systemctl status systemd-modules-load.service' and got the logs -> https://paste.pound-python.org/show/wr0UBuv2FfZKAw8pFC4p/
I should probably copy one of these xorg.conf files -
https://wiki.gentoo.org/wiki/NVIDIA/Optimus/xorg.conf
https://devtalk.nvidia.com/default/topic/1022670/linux/official-driver-384-59-with-geforce-1050m-doesn-t-work-on-opensuse-tumbleweed-kde/post/5203910/#5203910
But which one?
And do I need to just replace the BusID with my own?
In the wiki there is no settings for lightdm as a login manager. What should I be doing in my case to enable it on startup? (I am using lightdm + Gnome) |

I switched nvidia and intel in the screen 0 and inactive of the above mentioned xorg.conf. Now lightdm starts but gnome does not.
This is my journalctl -u lightdm -> https://paste.pound-python.org/show/CVzmMaP49OuksyXdyOdG/
DISPLAY=:0 xrandr --listproviders
| Code: | providers: number : 1
Provider 0: id: 0x45 cmp: 0x2. Sink Output crtcs: 3 outputs: 3 associated providers: 0 name:modesetting |

Glad that it works for you now but the config you're using now using the "load module" section is kind of depreciated. The reason is tearing. To get rid of tearing on an Optimus system, you'll have to enable PRIME sync using kernel parameter nvidia-drm.modeset=1 but then the config you're using will cease to work.
So you should try to get the config from the devtalk thread working. Post the xorg log if you run into trouble. |

In the dev talk xorg.conf (https://devtalk.nvidia.com/default/topic/1022670/linux/official-driver-384-59-with-geforce-1050m-doesn-t-work-on-opensuse-tumbleweed-kde/post/5203910/#5203910) apart from the BusIDs do I need to change anything? Do I need to change the resolution in the Monitor section?

| Not neccessarily, the resolution settings are just add-ons not changing anything in the normal run but are handy examples for workarounds for gaming. The virtual setting (if matching your screen resoltution) is a workaround for some games under wine, the modeline is an additional resolution to have available in Feral games. |

The virtual setting is not my screen resolution. Does it need to be? (I am not going to be gaming)
I tried that configurationin place of the Arch Wiki configuration. Unless my second display was on the left of my primary display, there was tearing.
