[SOLVED] No output untill I unplug second monitor

Hey there!
I reinstalled Arch with the proprietary drivers and Hyprland + Ly as Greeter.

Whenever I boot I get stuck at

starting systemd-udevd..

and the moment I disconnect my second monitor (DVI-D), everything unstucks at I see TTY or Ly.
Switching to TTY’s does not work  during this ‘stuck’ phase.

Everything works just fine after re-plugging the DVI-D cable, except the monitor big_smile The monitor goes to power saving mode indicating it receives no signal.

My hardware:
- Ryzen 5 3600
- GT 1030
- Primary HDMI monitor      (connected to GPU)
- Secondary DVI-D monitor (connected to GPU)
- Secondary GPU, that does not work at this current moment. (RX 470)

Outputs of some commands, that could help further diagnosis:

This command sometimes also displays the DVI-D but as disconnected. Not now after reboot and replug of the cable.

Thanks for any tips/help/notes!
Have a nice day fellow nerds big_smile

Re: [SOLVED] No output untill I unplug second monitor

Are you sure the other output is connected to the nvidia GPU?
Add

module_blacklist=amdgpu nvidia_drm.modeset=1 systemd.unit=multi-user.target

to the https://wiki.archlinux.org/title/Kernel_parameters (make sure you know how to edit them from the bootloader in case this goes south and you don't get to see any output) boot the system and run and post the output of

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

Re: [SOLVED] No output untill I unplug second monitor

Hey!
Thanks for the reply and sorry for the late response, I've been out the town for the week.

I've noticed, that whenever I manage to get into TTY and run Hyprland within TTY, the second monitor turns on and works as expected. But this does not work when ran from Ly as Hyprland..

I've noticed the AUR repo being down so I've downloaded read-edid and modified your command accordingly.

This is what I've run before applying kernel parameters with the second monitor working.

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

Re: [SOLVED] No output untill I unplug second monitor

Interestingly enough, the previous way of starting Hyprland manually doesn't seem to work anymore for the second monitor.

Anyways, heres the output of that command with those given kernel parameters.

Re: [SOLVED] No output untill I unplug second monitor

Ok, both outputs are connected to /sys/class/drm/card1

But this does not work when ran from Ly as Hyprland

Cut out ly for these tests, it's a horrible DM that breaks logind integration what means you'll liekly ending up lacking access permissions to several device nodes.
You can revisit and focus on getting that to work once the main situation has been sorted out while starting Hyprland from a console login.

heres the output of that command with those given kernel parameters

The (expectable) change is that card1 is now card0 because card0 is gone wink
But also card0-DVI-D-1 is gone?

heres the output of the command, but with Hyprland running just with the on screen.

Do you somehow manually transcribe these?
Don't!
Redirect them into files and/or 0x0.st

You might have to inject the edid, what means to first copy it from a boot where it shows up.
https://wiki.archlinux.org/title/Kernel … s_and_EDID
Unfortunately read-edid doesn't print the edid as hexadcimal block, otherwise we could have reconstructed it from there.


Sidebar:

I've noticed the AUR repo being down

I was about to throw a tantrum about somebody going for an asinine package deletion spree, but https://git.linuxtv.org/edid-decode.git/commit/
Just hasn't arrived in https://archlinux.org/packages/extra/x86_64/v4l-utils/ (yet)

Re: [SOLVED] No output untill I unplug second monitor

I've redirected the output from that command to file and copied its contents later on..
Given the tool not being able to print HEX, should I generate the edid stuff as shown in the wiki link, for you to check out?

Re: [SOLVED] No output untill I unplug second monitor

If the edid actually shows up w/ a boot you can just copy it.

cp /sys/class/drm/card0-DVI-D-1/edid /some/place/edid.bin

Re: [SOLVED] No output untill I unplug second monitor

Hey there!
For some reason suspending my computer and turning it back on makes the second monitor turn on!
No clue why that is..

Do you guys have any further tricks on potentional fixes?
Thanks and cheers!

Re: [SOLVED] No output untill I unplug second monitor

Can you now copy the edid ?
(It's likely only gonna be > 0B when the output actually works - which is why we want to extract and later inject it)

Re: [SOLVED] No output untill I unplug second monitor

I've checked every single subfolder of /sys/class/drm/ and yet failed to find even a single edid file that wasn't empty..
I guess it didn't get generated as I didn't actually boot, rather than just suspended (made my PC sleep).

I've found this GitHub repository. Perhaps I could just use one of those files?

Also nb. that you cannot infer the validity with "du" etc. - it'll always show 0 bytes. But copying it out of the sysfs will create an ~4kB big file.

Re: [SOLVED] No output untill I unplug second monitor

I've never even heard of edid, therefore I personally did not access it. Perhaps the system did, but no clue during what task it would.

I've copied out the EDID but still ls -la lists size as 0B, catting out the file shows nothing, file edid.bin shows it's empty.

And with that edid you've sent me, should I copy that and modify it accordingly to mine setup and afterwards set it to the bin somehow?

I've also noticed the card0-DVI-D-1 renaming to card0-DVI-D-2 for some reason, even tho the card has just one DVI-D port..

Once again sorry if I'm repeating some common stuff or not getting what you mean big_smile

Re: [SOLVED] No output untill I unplug second monitor

Saved those edid that were > 0 into /usr/lib/firmware/edid/..
I've set these kernel parameters:

GRUB_CMDLINE_LINUX="zswap.enabled=0 rootfstype=ext4 drm.edid_firmware=DVI-D-1:edid/DVI-D.bin,HDMI-A-1:edid/HDMI-A-1.bin"

as for initframs

MODULES=(usbhid xhci_hcd nvidia nvidia_modeset nvidia_uvm nvidia_drm)
BINARIES=()
FILES=(/usr/lib/firmware/edid/DVI-D.bin /usr/lib/firmware/edid/HDMI-A-1.bin)
HOOKS=(base udev autodetect microcode modconf keyboard keymap consolefont block filesystems  fsck)

yet after reboot I still was left on "Starting systemd-udevd version 2.."
second monitor still doesn't turn on even when launching Hyprland via TTY..

perhaps I've done some of this EDID stuff wrong?

Re: [SOLVED] No output untill I unplug second monitor

I've set these kernel parameters:

Did you regenerate the grub.cfg? Editing /etc/default/grub does nothing by itself - same goes for /etc/mkinitcpio.conf

You can "cat /proc/cmdline" to see whether your changes we applied.
And check the system journal for complaints about the provided EDIDs

I did update grub.cfg and ran mkinitcpio -P aswell (no errors in sight)

Re: [SOLVED] No output untill I unplug second monitor

Please post your complete system journal for the boot:

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

and

cat /proc/cmdline

You have to be in an elevated group or use sudo to see the system journal w/ journalctl, but if edid doesn't show up in that, you're not applying those kernel parameters.

It's there.

sudo ls /sys/kernel/debug/dri/{0,1,2}

And try to add "nvidia_drm.modeset=1 nvidia_drm.fbdev=0" to the kernel parameters.
You pretty much for sure what to get rid of the simpledrm device and disbaling fbdev doesn't really fit the symptoms but is worth a shot (also because the symptoms aren't super-clear wink

Re: [SOLVED] No output untill I unplug second monitor

Hold your horses.
See whether the behavior remains reliable.


But - if so, please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
