HDMI no signal after kernel update

pmarcinek · 2025-12-02 15:43:21

Hello,
i was successfully running Arch Linux on GIGABYTE-BACE-3160 on kernel <=6.5. I used i915 kernel module to utilize HDMI/VGA output. Everything worked great until i installed new system with the newest kernel.

Linux archlinux 6.17.9-arch1-1 #1 SMP PREEMPT_DYNAMIC Mon, 24 Nov 2025 15:21:09 +0000 x86_64 GNU/Linux

As a result i can see connected output:

[root@archlinux card1-HDMI-A-2]# xrandr -q

but i have no output on my monitor (monitor and cable is working properly with different HW).

I tried i915 and modesetting and the result was the same. I also tried xe driver which finally worked with very low resolution which is not acceptable solution.

Can you please help me with that problem?

Can you fix it by downgrading the kernel to the previous kernel? I'm asking as there were updates to other parts of the ecosystem (mkinitcpio, linux-firmware) aswell.

Star by getting rid of xf86-video-intel and that config.

Then please post your complete system journal for the boot:

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

The error will otherwise not be at the X11 level (at least I assume you're also not getting output on the console?)

Unfortunately i can't as i need to use the newest OS components - security requirement

I'm not asking to permanently downgrade, I just want to confirm whether our suspicion that the previous kernel would make it work is actually true.

seth · 2025-12-03 10:34:51

Unfortunately i can't as i need to use the newest OS components - security requirement

Dec 03 10:16:39 archlinux kernel: DMI: GIGABYTE GB-BACE-3160/MZBSWMP-00, BIOS F6 06/13/2018

So if the "newest OS component" had a massive CVE you're not allowed to downgrade to an unaffected version?
Who comes up w/ that kind of retarded shit?
Try the newest LTS kernel …

Dec 03 10:20:58 archlinux sshd-session[552]: Accepted password for root from 192.168.11.247 port 35148 ssh2
Dec 03 10:20:58 archlinux sshd-session[552]: pam_unix(sshd:session): session opened for user root(uid=0) by root(uid=0)
Dec 03 10:20:58 archlinux systemd-logind[352]: New session '2' of user 'root' with class 'user' and type 'tty'.

Also tell that sEcUrItY clown to ban root logins via ssh. FFS.

There're no i915/drm related errors and no complaint about missing crtc, but you#re booting straight into lightdm.
Try to only boot the multi-user.target (2nd link below) and or switch the VT (ctrl+alt+f3)

"i915.nuclear_pageflip=1 intel_idle.max_cstate=1 i915.enable_dc=0 i915.enable_fbc=0 i915.enable_psr=0" are already mitigation efforts?
If you don't get an output on the console either, try to blacklist i915 (you'll be running XGA on the simpledrm device, we just want to see whether the output generates a signal at all)

Does your security expert allow you to boot a different SW stack, eg. a live distro like grml.org so we can rule out broken HW?

It didn't help. No matter if i use i915 or modesetting i got only cursor flickering in top-left corner. I downgraded to 6.4.6

The security team is checking CVE before image is pushed to production. If there is newer available version, they always push to upgrade.
This specific OS is for testing purposes only - that's why root login is enabled.
The kernel parameters are part of mitigations efforts.
Currently i'm running on:

Linux archlinux 6.12.60-1-lts #1 SMP PREEMPT_DYNAMIC Mon, 01 Dec 2025 13:15:19 +0000 x86_64 GNU/Linux

The effect is exactly the same. If i boot on VGA, then i can see login prompt on tty1. If i boot on HDMI, there is only black screen and "No signal detected" on monitor displayed.
If i blacklist i915 on kernel parameters then i can see login prompt and i can start lightdm and login to graphical environment.
Unfortunately, the monitor is not properly recognized:

[root@archlinux ~]# xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
None-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768      60.00*+

It looks that EDID is missing:

[root@archlinux ~]# cd /sys/class/drm/card0-Unknown-1/
[root@archlinux card0-Unknown-1]# ls -al
total 0
drwxr-xr-x 3 root root    0 Dec  3 12:26 .

[root@archlinux card0-Unknown-1]# cat edid 
[root@archlinux card0-Unknown-1]#

Then i upgraded to newest kernel (not LTS) and the effect is the same as above - login prompt and lightdm available with low resolution.

Unfortunately, the monitor is not properly recognized:

That's normal, the simpledrm device only supports some VESA modes (you don't want to use that thing anyway)

If you boot w/o blacklisting i915 but with "video=1024x768@60", https://www.kernel.org/doc/Documentation/fb/modedb.rst to the multi-user.target, do you get some signal on the HDMI monitor?
If you start lightdm and in doubt from the console or via ssh

DISPLAY=:0 xrandr --mode 1024x768 --rate 60

, does the monitor then get a signal?

You should from there also be able to get the EDID and can just cat "edid | curl -F 'file=@-' 0x0.st"
For local inspection or to find it run

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

You'll need https://archlinux.org/packages/extra/x86_64/v4l-utils/

If boot w/o blacklisting i915 and video kernel parameter set then i get "No signal" on monitor. I can start lightdm via console and blindly login to graphical session. EDID file seems to be ok:

If i try running xrandr command with lightdm started it looks that the resolution is changed but there is still no signal on monitor:

Not sure if that helps but i tried to boot with arch netboot image and there is also no signal effect (during netboot image run).
I also tried to install Ubuntu and after rebooting and connecting to HDMI port there is also no signal.
I've done these tests on 3 boards (each one exactly the same model) and 2 monitors (2 different models) - it looks this problem is more general.

Since it's coming w/ the i915 module and kernel downgrades and the resolution have no impact I'd suggest to downgrade linux-firmware-intel

Tried to downgrade and completely uninstall - still no change

Maybe it's somehow related to xorg-server as the effect is the same with i915 and modesetting driver?

seth · 2025-12-05 09:54:08

Do you get a signal on the console (multi-user.target)?
If not, it cannot be x11.
