Black screen on boot after system upgrade

sheraff · 2024-03-20 09:22:10

Аble to boot only with 'nomodeset' parameter in GRUB, otherwise getting black screen with 'No signal'.

Intel XE graphics (NUC), standard setup with systemd, X, mesa, GDM, Gnome, Xfce4. Followed the installation guide, used only standard and recommended packages.
Been working for years with this or similar Arch config or various machines (1+ year work this particular one), including laptops, using native and external monitors. In fact, my laptop boots fine after upgrade, with same config...

(Dual) boot to Windows works fine, so it's not a hardware/cable problem. What freaks me out, occasionally Linux also boots, even after the trouble had appeared...

Tried (with nomodeset param) to rebuild init with mkinicpio, seemed to cure the problem, but then failed at next boot.

Would someone kindly help diagnose and fix the problem, or how to quick fix it until the working package is issued? Maybe to clear some static settings so they would be automatically renewed?

Enable REISUB: https://wiki.archlinux.org/title/Keyboa … el_(SysRq) boot into the faulty kernel, use the REISUB sequence to safely reboot, boot with nomodeset and post the journal of the failing boot with

sudo journalctl -b-1

Consider installing the LTS kernel so you can continue having a working graphical setup.

Please have a look.

Should have used it as a rule.
Thanks for your attention to my question.

Re-plug the cable.

Maybe that's some connectivity test that fails with new kernel.
Faced same trouble at another connection spot (monitor/cable).

Here's what current boot journal says, with linux-lts.
Also, Windows boot runs smoothly...

Maybe not.
Is it HDMI?
There's a hyper-fragile handshake involved that doesn't tolerate any delay during the handshake and there's a bogus MST related test/warning during the init.
HDMI/DP "cables" aren't just some copper, there's a minicomputer in each of the plugs.

1. does the LTS kernel work?
2. does re-plugging the cable work?

1. Yes, it works just fine.
2. I use this machine at two different spots, plugging and replugging. 'No signal' on both of them after last kernel upgrade.
I use HDMI cables provided with the monitors.
After downgrade to linux-lts, all works fine.

Boot logs:
6.6.22-1-lts
6.8.1-arch1-1
If it helps the community to trace the problem to avoid it in future releases.

This here is the warning that *maybe* tumbles hdcp

бер 20 18:24:20 aPanther kernel: WARNING: CPU: 7 PID: 163 at drivers/gpu/drm/i915/display/intel_dp.c:3193 intel_dp_sink_disable_decompression+0x63/0xf0 [i915]

but the journal is only 28s and doesn't seem to contain a re-plug event?

After re-plugging the cable, does the output show up in xrandr or

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

Edit: you btw. do not want to use the xf86-video-intel driver w/ a tigerlake chip, but if you'd insist still set "DRI" to "iris"

This something out of my control currently.
Will dive into it )

Visually didn't see any difference, I believe something good happened
