[SOLVED] No HDMI output after systemd-udev starts. | Arch Linux Community | Page 1

Hi. My computer stops displaying video output during early boot, right after the "Starting systemd-udevd version 257.7-1-arch" line. Before that display is working fine.

I've tried several times to start the situation doesn't change. First the computer boots to systemd, i'll select the regular Arch entry, the Arch Linux splash screen shows up, then the logs and right after the aforementioned line the displays goes blank, as in no signal is detected by the screen.

The computer was recently moved by car. The usual set
up is made of 2 screens over display port but it changed to a single Samsung TV over HDMI when the issue started. It might be unrelated as the computer sat unused for 2 weeks before that.

The issue doesn't seem hardware related as booting into windows works fine. The graphics card is also recognised by windows.

I first tried to reseat the graphics card in its PCIE port.

I then tried start my DE without display. Which seems to work as the keyboard rgb daemon starts as usual upon connection.

I tried chrooting into the Arch partition (it's display works), checking bootloader entries, running "pacman -Syu" and letting it update.

I cannot access the TTY when booted normally, while it does appear to switch to the TTY, the display stays blank.

Relevant setup:
GNOME DE, Wayland, ssdm. RTX 3080ti with up-to-date nvidia proprietary drivers. Intel i7-12700f processor. The computers boots via UEFI. Arch was installed a year ago via archinstall. Secure boot is disabled.

Attached is a picture of the screen right before the HDMI signal is lost by the TV. The signal is lost after this line every time.

@harsh sierra rebuild initramfs in chroot

harsh sierra Jul 18, 2025, 10:29 PM

#

Alright i'll try that and come back in a few minutes. Thanks for your help.

tacit portal Jul 18, 2025, 10:30 PM

#

harsh sierra Alright i'll try that and come back in a few minutes. Thanks for your help.

#

This unfortunately didn't solve the issue. Here is the output log of mkinitcpio which appears to have executed without issues. I unfortunately cannot copy paste this for obvious reasons.

tacit portal Jul 18, 2025, 10:41 PM

#

what gpu?

harsh sierra Jul 18, 2025, 10:42 PM

#

Rtx 3080ti from evga, I don't know the exact model.

tacit portal Jul 18, 2025, 10:42 PM

#

see if it works with the nomodeset kernel param

harsh sierra Jul 18, 2025, 10:43 PM

#

Alright, I'll try that. Thanks.

#

Still no video output unfortunately. Here are all kernel parameters used when booting.

tacit portal Jul 18, 2025, 10:48 PM

#

try a different hdmi cable

harsh sierra Jul 18, 2025, 10:49 PM

#

This one seems to work well enough for windows to function normally at the 4k/60HZ resolution. I will still try to find another one.

tacit portal Jul 18, 2025, 10:55 PM

#

working? @harsh sierra

harsh sierra Jul 18, 2025, 10:57 PM

#

I was unable to find another cable

#

But I'm pretty confident in the current cable's condition.

#

I won't be able to rule that out for now.

tacit portal Jul 18, 2025, 10:58 PM

#

@harsh sierra pacman -Qs nvidia

harsh sierra Jul 18, 2025, 10:58 PM

#

Alright let me just reboot into chroot.

#

tacit portal Jul 18, 2025, 11:03 PM

#

@harsh sierra try systemd initramfs

#

replace udev and base with systemd in /etc/mkinitcpio.conf

harsh sierra Jul 18, 2025, 11:05 PM

#

Like so ? Then i reboot ? Or run mkinitcpio ?

tacit portal Jul 18, 2025, 11:06 PM

#

mkinitcpio -P

#

then reboot

harsh sierra Jul 18, 2025, 11:12 PM

#

The start logs have changed but the video still drops after this. There are also some kind of freeze in the video output where no new logs are output for a few instants before the signal is lost.

I was unable to get a better view as it was printing quite fast.

tacit portal Jul 18, 2025, 11:13 PM

#

harsh sierra The start logs have changed but the video still drops after this. There are also...

try linux-lts

harsh sierra Jul 18, 2025, 11:14 PM

#

Alright, by executing pacman -S linux-lts in the chroot ?

tacit portal Jul 18, 2025, 11:14 PM

#

yes

#

you will have to add another systemd-boot entry for it

#

https://wiki.archlinux.org/title/Systemd-boot#Adding_loaders

#

@harsh sierra working?

harsh sierra Jul 18, 2025, 11:27 PM

#

I'm writing the loader file

#

There were some errors during the installation of linux-lts

tacit portal Jul 18, 2025, 11:27 PM

#

i need the full log

#

bigger picture

tacit portal Jul 18, 2025, 11:29 PM

#

harsh sierra There were some errors during the installation of linux-lts

pacman -Rns nvidia
pacman -S nvidia-open-dkms

#

@harsh sierra run this

#

to fix

harsh sierra Jul 18, 2025, 11:33 PM

#

Alright here is the full log for the linux-lts install

tacit portal Jul 18, 2025, 11:34 PM

#

tacit portal pacman -Rns nvidia pacman -S nvidia-open-dkms

@harsh sierra

harsh sierra Jul 18, 2025, 11:34 PM

#

And here is the (hopefully) in order log of the nvidia-dkms install

tacit portal Jul 18, 2025, 11:35 PM

#

@harsh sierra

#

reboot and see

#

remove those from mkinitcpio.conf

#

no need when using dkms

harsh sierra Jul 18, 2025, 11:41 PM

#

Okay i'll do that

#

Okay it works now ! Thank you very much for your help

#

However the display seems to be stuck at 1024x768

tacit portal Jul 18, 2025, 11:49 PM

#

remove nomodeset from kernel params

harsh sierra Jul 18, 2025, 11:50 PM

#

Here were the logs during mkinitcpio

harsh sierra Jul 18, 2025, 11:50 PM

#

tacit portal remove nomodeset from kernel params

Alright i'll try that

#

I don't see nomodeset in the kernel parameters

#

tacit portal Jul 18, 2025, 11:53 PM

#

@harsh sierra modinfo nvidia

#

in boot

harsh sierra Jul 18, 2025, 11:54 PM

#

The original entry had "nvidia-drm.modeset=1" perhaps this is related ?

harsh sierra Jul 18, 2025, 11:54 PM

#

tacit portal <@475239330584199169> modinfo nvidia

As a kernel parameter ?

tacit portal Jul 18, 2025, 11:55 PM

#

?

harsh sierra Jul 18, 2025, 11:55 PM

#

I don't understand what you've asked me to do sorry

tacit portal Jul 18, 2025, 11:55 PM

#

harsh sierra The original entry had "nvidia-drm.modeset=1" perhaps this is related ?

try adding it

harsh sierra Jul 18, 2025, 11:56 PM

#

I don't think that the nvidia drivers are loaded

harsh sierra Jul 18, 2025, 11:56 PM

#

tacit portal try adding it

I'll try

tacit portal Jul 18, 2025, 11:57 PM

#

harsh sierra I don't think that the nvidia drivers are loaded

stop

tacit portal Jul 18, 2025, 11:57 PM

#

harsh sierra I'll try

stop

harsh sierra Jul 18, 2025, 11:57 PM

#

I'm stopping

tacit portal Jul 18, 2025, 11:57 PM

#

pacman -Rns nvidia-open-dkms
pacman -S nvidia-open-lts
reboot

harsh sierra Jul 19, 2025, 12:00 AM

#

Now the HDMI output fails on boot again, the startup goes a lot further than before however.

tacit portal Jul 19, 2025, 12:06 AM

#

harsh sierra Now the HDMI output fails on boot again, the startup goes a lot further than bef...

i suspect the problem is with linux-firmware-nvidia

#

pls try downgrading that

harsh sierra Jul 19, 2025, 12:07 AM

#

Alright which version should I get ?

#

The second newest ?

tacit portal Jul 19, 2025, 12:08 AM

#

show me the options

#

with downgrade

harsh sierra Jul 19, 2025, 12:09 AM

#

I'm not getting the usual menu I think it needs Internet, I'll set it up

tacit portal Jul 19, 2025, 12:10 AM

#

if it does not have internet it will fetch related packages from ur cache

harsh sierra Jul 19, 2025, 12:11 AM

#

tacit portal Jul 19, 2025, 12:12 AM

#

the earliest pls

#

harsh sierra Jul 19, 2025, 12:12 AM

#

Okay

#

Still no luck, here is the last log before losing HDMI

#

I have a video of the whole startup if that's necessary

tacit portal Jul 19, 2025, 12:38 AM

#

@harsh sierra it's something to do with ur gpu

harsh sierra Jul 19, 2025, 12:39 AM

#

I'll try to stress test it with furmark on windows then

#

I think i'll just end up reinstalling everything if it turns out okay

tacit portal Jul 19, 2025, 12:40 AM

#

harsh sierra I think i'll just end up reinstalling everything if it turns out okay

reinstalling is not a good option

#

it doesn't help you learn

#

it's an escape

harsh sierra Jul 19, 2025, 12:46 AM

#

Well i feel like i'm running out of options there

#

Anyway the GPU survived the furmark Burn-in test with 5200 points

#

Which is a little low but it can be explained by the 90% power limit

tacit portal Jul 19, 2025, 12:47 AM

#

@harsh sierra drivers, relating to gpu, it worked when you didn't have them installed

harsh sierra Jul 19, 2025, 12:47 AM

#

Oh yeah right sorry i didn't understand

#

Isn't there a way to just remove everything nvidia related to redo the driver installation cleanly ?

#

You're right it's certainly driver related, the normal boot entry works when it uses the default driver

tacit portal Jul 19, 2025, 12:52 AM

#

harsh sierra You're right it's certainly driver related, the normal boot entry works when it ...

?

#

what normal entry

harsh sierra Jul 19, 2025, 12:52 AM

#

The non-lts one ?

#

The one i used previously

tacit portal Jul 19, 2025, 12:53 AM

#

the normal entry is working?

#

brb

harsh sierra Jul 19, 2025, 12:54 AM

#

Yes but not at full resolution unfortunately, I think it's because the installed drivers are made for the lts kernel

tacit portal Jul 19, 2025, 12:58 AM

#

well yes

harsh sierra Jul 19, 2025, 1:26 AM

#

Okay so I tried to update the drivers while inside the regular kernel. It worked for a minute then blanked as before.

#

I pulled the logs from right when the screen blanked

#

I guess the driver is getting confused by the TV or there are conflicts between monitor settings

harsh sierra Jul 19, 2025, 2:11 AM

#

It works ?

tacit portal Jul 19, 2025, 2:11 AM

#

... solved
