[Solved] xorg startup (and reverse PRIME) broken, nvidia 455.45.01-6

Hi everybody,

for people encountering the same issue: Since upgrading to at least nvidia 455.45.01-6 lightdm startup on my machine was broken and resulted in booting to terminal.

A simple
systemctl restart lightdm
after waiting a bit fixed this issue.

Since upgrading to nvidia 455.45.01-7, lightdm starts again immediately after boot, however reverse prime is broken (only one output sink).
Again: restarting lightdm makes the second problem go away, too.

My best guess: Somehow my nvidia card (mobile Geforce 1060 with HDMI hooked up to nvidia) takes longer to initialize after the module is loaded than lightdm.

Best,
Bas
