[SOLVED] booting issues after running pacman -Syu

Hi you all,
I've got kind of a problem. Yesterday evening i updated my system, ran "sudo pacman -Syu" und shut my laptop down after that.

Today, when I wanted to boot the laptop, everything went normal, until the login screen. I saw it flashing for a split second, after that a blackscreen with some backlight flashings.

I use KDE Plasma on x.org on this hardware:
Framework Laptop
Core i7-1165G7
2x16GB DDR4-3200 RAM
Intel Iris Xe-Graphics

On the system is also a full install of gnome, including gdm installed, but basicly never used and, in the case of gdm, deactivated.

This are the packages that were updated

expat
krb5
libffi
apache
clang
dbus
gnutls
libdrm
libva
faudio
fluidsynth
graphviz
sqlite
kwayland-integration
layer-shell-qt
lib32-dbus
lib32-expat
lib32-faudio
libebml
libjxl
libmatroska
libmaxminddb
linux
noto-fonts
qt6-translations
qt6-base
qt6-svg
qt5-studio
obs-studio
openpmix
perl-ffi-checklib
perl-xml-libxml
php
pinentry
plasma-workspace
protobuf
python-fastbencode
python-jarowinkler
python-rapidfuzz
python-levenshtein
qpdf
python-pikepdf
python-pyopenssl
python-rich
python-setuptools
python-sphinx
sdl12-compat
virtualbox-host-modules-arch

I hope, someone can help me.
Flo

Re: [SOLVED] booting issues after running pacman -Syu

There's a bug in 5.19.12 with intel graphics and certain laptops/panel displays, downgrade linux to 5.19.11 or upgrade to 5.19.13 from testing (or wait for that to be moved to stable, should be soon)

Should be in core, update from an up to date mirror, if you don't have a live usb handy to do the update, try booting with "systemd.unit=multi-user.target nomodeset" on your kernel cmdline and do the update from a terminal.

Thanks for your quick answer, but unfortunally this didn't work. I tried another update, a downgrade to 5.19.11, as well as the kernel parameter, i always got the same symptoms.

Re: [SOLVED] booting issues after running pacman -Syu

How sure are/were you you downgraded/upgraded correctly? Are all the partitions properly mounted? Running uname -a from a relevantly up or downgraded system should show the respective new kernels and the symptoms very much sound like that issue.

Are you able to switch VTs during the flashing? Ctrl+Alt+F2 and friends? If so post a journal log

sudo journalctl -b

if not, chroot from the live disk and post

journalctl -b-1

from the chroot: https://wiki.archlinux.org/title/List_o … n_services

Re: [SOLVED] booting issues after running pacman -Syu

I found the reason why it didn't work: There was still data from a hibernated session in the swap, which it always reanimated back, with the .12-version of the kernel. I cleared the swap from the chroot (swapoff --a, wait a little bit, then swapon -a), rebooted into the main install of arch et voila: No flashing, no blackscreen, just my login screen.

Thanks again for the quick help.
