[SOLVED] external monitor not detected on optimus laptop

BananPrzydawka · 2024-04-10 19:24:43

got a laptop with an external monitor hooked up, it worked, and and now it dont. i know the monitor works as i can use it with not problem on windows, and i think windows isnt the problem as on that end nothing has changed. for all the posts i found the solution was to enable nvidia drm modesetting, witch i do have.

sudo journalctl -b | curl -F 'file=@-' 0x0.st

[url]http://0x0.st/X--i.txt[/url]

cat /proc/cmdline

BOOT_IMAGE=/boot/vmlinuz-linux-lts root=/dev/mapper/volgroup0-lv_root rw nvidia-drm.modeset=1 loglevel=3 quiet resume=UUID=af9def61-137f-43f3-a181-cea8b9db36c2 resume_offset=4161536

xrandr --listmonitors

The journal is 2 days worth of PCI errors, but I saw that you're running kwin_wayland, so xrandr is less relevant.
Please reboot and post the journal of that boot to cut out the noise, also try the behavior w/ a plasma/X11 session (assuming that's what you've been using before)

BananPrzydawka · 2024-04-10 21:04:28

sorry, heres the log after a fresh boot on plasma x11

Thanks, 2400 lines is much more handleable.

nvidia loads relatively late, notably after SDDM.
Does the second output appear if you restart SDDM after the boot?

lmao

the second output does not appear after restarting sddm after boot.

i already have all the modules added from the resource you linked

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm i915)

also, seth you are an absolute machine and you were the person helping in every single one of the related issiues i read.

for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; done

You'll need https://aur.archlinux.org/packages/edid-decode-git

(liekly) Unrelated to that (because you're not getting the output w/ an SDDM restart), are you sure you've the modules in the initramfs? Did you regenerate it after editing the mkinitcpio.conf?
The module isn't loaded before the remount.

the modules have been added for probably a year since my last graphical issiue, and i have regenerated initramfs for sure.

lsinitcpio /boot/initramfs-linux-lts.img | grep nvidia

but what's more concerning is that the card doesn't show up as drm device?
There's no /sys/class/drm/card1* ?
Does the GPU respond to nvidia-smi ?
Did you enable https://wiki.archlinux.org/title/PRIME# … Management ?

lsmod | grep nvidia
modprobe -c | grep -v alias | grep nvidia # prints nvidia-related module options
lsblk -f # by a long shot, you're booting from the root partition, maybe a spurious boot partition is mounted into /boot
pacman -Qikk nvidia-lts nvidia-utils # package integrity

This all doesn't add up - the nvidia module seems in the initramfs but loads after the root switch.
The GPU responds, the nvidia module loads and there's even

but no drm device to be seen.

Also please post your xorg log, because apparently the the nvidia GPU is ignored (not showing up in the smi processes)

Why is this there?

blacklist nvidia
blacklist nvidia_drm
blacklist nvidia_modeset
blacklist nvidia_uvm

grep -r nvidia /etc/modprobe*

The xorg log is of normal length and reflects the status quo - the nvidia GPU is ignored, presumingly because the nvidia-drm outputclass doen't match, because nvidia-drm isn't loaded.
Presumingly because of the blacklist…

BananPrzydawka · 2024-04-13 12:46:14

i dont know why the blacklists are there, even worse im unable to find them, as /etc/modprobe.d/ is empty, and they arent defined in kernel command line in my /etc/default/grub file.

seth · 2024-04-13 12:48:00

Probably stale in your initramfs, try to regenerate that.

BananPrzydawka · 2024-04-13 12:52:57

already tried that, still blacklisted. also regenerated grub config, same idea, and same result. still blacklisted.

seth · 2024-04-13 13:20:35

There're other modprobe .conf locations, https://man.archlinux.org/man/core/kmod … n#SYNOPSIS

Otherwise:

lsblk -f

You're booting from the root partition, if anything is mounted into /boot, you're writing the initramfs into the wrong location.

BananPrzydawka · 2024-04-13 13:53:54

found the blacklists in /lib/modprobe.d/nvx.conf. removed them, regenerated initramfs and rebooted. this seems to have fixed all my issiues. although i have no idea why the blacklists were even there in the first place. thank you so much.

seth · 2024-04-13 14:38:29

That file is from https://aur.archlinux.org/packages/nvidia-exec - make sure you don't have the package around anymore or it'll likely recreate the file at some poitn (w/ an update)
