Re: I have a problem with my gpu and arch linux

That's the simpledrm device - is this w/ a "nomodeset" boot? (that's pointless - we're using ssh to look at the broken system)

Re: I have a problem with my gpu and arch linux

Great. No EDID. Likely why amdgpu thinks there's no output.

With  a little luck https://github.com/linuxhw/EDID/blob/ma … ADABB78D4D is your monitor.
http://0x0.st/8nNj.bin is the binary of that, try to inject that:  https://wiki.archlinux.org/title/Kernel … s_and_EDID

Re: I have a problem with my gpu and arch linux

Unfortunately I tried doing this but it still doesn't work. I might've done something wrong but I'm not sure. Anyways here's the system journal for that boot http://0x0.st/8nbo.txt

Re: I have a problem with my gpu and arch linux

Still it's not working but I feel like this is going into the right path. This is the boot http://0x0.st/8ncr.txt

Re: I have a problem with my gpu and arch linux

http://0x0.st/8nbo.txt still has

Jul 21 19:34:09 archlinux kernel: amdgpu 0000:08:00.0: [drm] Cannot find any crtc or sizes

http://0x0.st/8ncr.txt stops w/ the journal sync after the initramfs (so you might have rebooted that w/ the power button)

I think I know what might be going on …  I feel like this is going into the right path

"namely"?

Do you have more luck w/ forcing the output to be enabled?
https://wiki.archlinux.org/title/Kernel … cing_modes

Have you tried the other monitor?

Re: I have a problem with my gpu and arch linux

Yeah I think I'll try the other monitor because this is just annoying

Re: I have a problem with my gpu and arch linux

So the problem all along was the monitor
I didn't expect that but thank you so so much for helping I'd never figure it out

Re: I have a problem with my gpu and arch linux

Well, yeah - sort of.
The monitor clearly works before KMS - is it attached via HDMI or DisplayPort?

Injecting the edid btw. failed because "drm.25ADABB78D4D.txt=edid/8nNj.bin" is complete nonsense.
You could fix that and try again.

Re: I have a problem with my gpu and arch linux

I tried doing it correctly using "edid_firmware" but it still doesn't work. Should I also change the bin thing? And also its attached via hdmi

Re: I have a problem with my gpu and arch linux

Can we see the "corretly using" journal?

cat /proc/cmdline
ls -l /usr/lib/firmware/

Re: I have a problem with my gpu and arch linux

ls -l /usr/lib/firmware/edid

But you can pipe everything into 0x0.st

ls -l /usr/lib/firmware/edid | curl -F 'file=@-' 0x0.st

Also your journal, please.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

What is that?
You're supposed to put the binary EDID into that location and reference it as "drm.edid_firmware=edid/8nNj.bin" and in case you've amdgpu in the initramfs, you'll also have to add the edid  to the FILES array in your mkinitcpio.conf and regenerate the initramfs.
See https://wiki.archlinux.org/title/Kernel … s_and_EDID again.
