Black screen Nvidia optimus

_Benjamin753 · 2022-02-16 15:35:20

I'm using an Nvidia optimus setup, but recently (presumable since an update) Nvidia is no longer working (it boots into a black screen). The archwiki says that this might be because of a conflict with my intel graphics, when adding the suggested solution to modprobe still gives a black screen, but with a blinking dash in the left-upper corner.

The following is my config:

/etc/X11/xorg.conf.d/99-nvidia.conf

Section "Module"
    Load "modesetting"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver  "nvidia"
    BusID   "PCI:1:0:0"
    Option  "AllowEmptyInitialConfiguration"
EndSection

Section "Extensions"
    Option  "Composite" "Enable"
EndSection

I don't see unexpected errors or warnings in my dmesg (this is before I blacklisted Intel GPU modules).

Anyone knows how to solve this one?
Thanks in advance!

Most relevant info would be https://wiki.archlinux.org/title/Xorg#General

black screen, but with a blinking dash in the left-upper corner

suggests you'll benefit from https://wiki.archlinux.org/title/Kernel … _KMS_start

Adding the Nvidia modules to kms did not change the problem.
I forgot to list my xorg logs they are listed below.

Xorg.0.log.old ends with an error (without description)

You're running on the nvidia chip, but there're no outputs attached.
https://bbs.archlinux.org/viewtopic.php … 7#p2022497 suggests that previously something did (do you use sddm?) did an implicit reverse prime output redirection for you - that's not happening and so you get a black screen.
The abort in the first log looks like https://bbs.archlinux.org/viewtopic.php?id=274158 - no idea where that's coming from atm.
