External Monitor on laptop disconnecting/reconnecting; no output (HDMI, Nvidia )

[mellow hawk]

Update: now my computer does not even identify the monitor at all. There is no display in xrandr, or in the settings

@mellow hawk nvidia or nvidia-open?

[mellow hawk]

nvidia-open, I believe

i have just run the install for nvidia-open and nvidia-utils, im not sure if I am supposed to do this

[mellow hawk]

if it is any information, I have a 3060 laptop GPU

lspci -k | curl -F 'file=@-' 0x0.st

[mellow hawk]

i have found a potential solution from https://bbs.archlinux.org/viewtopic.php?id=287510, but 1. I don't know how to modify kernel parameters and 2. this only solves problems in wayland KDE plasma (i think)

@mellow hawk reboot

smash e

add nvidia-drm.modeset=1 to the end of it

linux /boot/vmlinuz-linux root=UUID=0a3407de-014b-458b-b5c1-848e92a327a3 rw

this line

[mellow hawk]

give me one second

[noble folio]

press x to boot when you add that

if it works, add it to your grub config between the quotes in the GRUB_CMDLINE_LINUX_DEFAULT line

[mellow hawk]

i am using systemd, does that change anything?

[mellow hawk]

this screen?

[noble folio]

yes

[noble folio]

then do this https://wiki.archlinux.org/title/Kernel_parameters#systemd-boot

[mellow hawk]

add both the nvidia-drm line and the linux /boot? or just the nvidia-drm

[noble folio]

photo please

[mellow hawk]

after this, do I add this line also

[noble folio]

just like that

[mellow hawk]

then hit enter to boot yes?

[noble folio]

yes

[mellow hawk]

I have done that, there is no difference

[noble folio]

are you sure?

you needed nvidia instead of nvidia-open

[mellow hawk]

let me check

I will try again now

[mellow hawk]

yes, I am sure, it did not seem to do anything.

xrandr still shows the same output

[noble folio]

@mellow hawk pacman -Q nvidia

[mellow hawk]

"nvidia 570.144-3"

[noble folio]

@mellow hawktry the lts kernel with nvidia-open-dkms

[mellow hawk]

should i still use the nvidia-drm boot setting?

[noble folio]

keep it, if it does not work, remove it

[mellow hawk]

both with and without did not work, unfortunately

[noble folio]

with the lts kernel installed and being on?

[mellow hawk]

yes, I have tried both lts and standard with and without drm boot setting

[noble folio]

did you make the loader? https://wiki.archlinux.org/title/Systemd-boot#Adding_loaders

[mellow hawk]

what does this mean? im not sure i understand the page...

[noble folio]

@mellow hawk how did you boot into the lts kernel?

try nvidia-dkms instead, with and with out the kernel param

[mellow hawk]

from this menu, i selected the linux-lts option instead of th linux option

[mellow hawk]

in linux or linux-lts?

[noble folio]

lts

[noble folio]

then nvidia-lts

[mellow hawk]

tried all 4, no dice
