sway-nvidia.desktop doesn't work from LightDM

[diocletiann]

Thanks for making these scripts, exec sway-nvidia works great from a tty. When using the DM .desktop entry, LightDM tries to start Sway and you can see the display changing modes, but after a few seconds I'm back at the greeter login screen. I looked at the .desktop file and it's just running sway-nvidia so I'm not sure what the issue is.
