Problem with nvidia-drm.modeset=1 and external monitors when booting

Graphics / Linux Linux

I have the current setup:

  • Laptop Lenovo Legion 5 with Nvidia RTX 2060
  • 1 external monitor hooked to hdmi
  • 2 external monitors hooked to usb-c (via a usbc hub that has 2 hdmi slots)
  • Arch Linux and latest nvidia drivers (nvidia-dkms 510.54-1)

Now here’s what happens, when I set nvidia-drm.modeset=1 in GRUB, right after “quiet” (where I also have iommu set):

  • If the 2 external monitors (usb-c) are not connected during boot , the system boots normally (and I can connect them afterwards and they’ll work just fine)
  • If the 2 monitors are connected during boot , the DM would just freeze (tried lightdm and sddm), and I cannot even hit ctrl+alt+fX

I tried disabling /etc/X11/xorg.conf and all files under /etc/X11/xorg.conf.d, without success.

here’s my journalctl -p 3 -b output

journalctl -p 3 -b

Any hints?

@adis.durakovic
I will try to prepare similar setup locally and attempt to reproduce issue.

By the way, can you please confirm which dock station model are you using.
Also please share once bug report from repro state.

This is the dock I’m using. https://www.amazon.de/-/en/gp/product/B08X14KRMB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

Unfortunatelly, I cannot post any bug reports from repro state, since my mouse and keyboard don’t work when the problem occurs.

With 515, this is the latest journalctl output I get when the error occurs: Mai 17 18:47:12 archlegion kernel: Linux version 5.17.7-arch1-1 (linux@archlinux - Pastebin.com
