[SOLVED] KDE Plasma 6 && SDDM && Nvidia SEGFAULT after start

Hello,

I have just completed a clean installation of Archlinux, on my ASUS Rog Strix G17 (2022) laptop. I decided to install KDE Plasma 6, Wayland and SDDM.
When I launch a Wayland session, it stays in black screen for a long time, then launches normally and then I have about 2 minutes (during this short time, the system suffers from severe lags) before it closes and asks me to connect again, if I do I'll have an infinite black screen.
For X11, the same thing happens, but at the end a crash report window opens. According to KDE's crash report software, the cause of the problem is a segfault on /usr/bin/plasmashell (for X11).
TTY use poses no problem.

Hardware configuration:

  • AMD Ryzen 6800H (with integrated GPU)

  • NVIDIA RTX 3060.

I've configured my machine to have :

  • NVIDIA proprietary driver

  • Use ONLY the dedicated GPU

My objective is to have a “stable” Wayland configuration.

Here is my startup configuration :

cat /etc/mkinitcpio.conf
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(usbhid xhci_hcd)
MODULES=(btrfs nvidia nvidia_modeset nvidia_uvm nvidia_drm)

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=()

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No RAID, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect modconf block filesystems fsck)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev modconf block filesystems fsck)
#
##   This setup assembles a mdadm array with an encrypted root file system.
##   Note: See 'mkinitcpio -H mdadm_udev' for more information on RAID devices.
#    HOOKS=(base udev modconf keyboard keymap consolefont block mdadm_udev encrypt filesystems fsck)
#
##   This setup loads an lvm2 volume group.
#    HOOKS=(base udev modconf block lvm2 filesystems fsck)
#
##   This will create a systemd based initramfs which loads an encrypted root filesystem.
#    HOOKS=(base systemd autodetect modconf keyboard sd-vconsole sd-encrypt block filesystems fsck)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr and fsck hooks.
HOOKS=(base systemd plymouth keyboard autodetect microcode modconf block sd-vconsole sd-encrypt filesystems fsck)

# COMPRESSION
# Use this to compress the initramfs image. By default, zstd compression
# is used for Linux ≥ 5.9 and gzip compression is used for Linux < 5.9.
# Use 'cat' to create an uncompressed image.
#COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()

# MODULES_DECOMPRESS
# Decompress loadable kernel modules and their firmware during initramfs
# creation. Switch (yes/no).
# Enable to allow further decreasing image size when using high compression
# (e.g. xz -9e or zstd --long --ultra -22) at the expense of increased RAM usage
# at early boot.
# Note that any compressed files will be placed in the uncompressed early CPIO
# to avoid double compression.
#MODULES_DECOMPRESS="no"

Re: [SOLVED] KDE Plasma 6 && SDDM && Nvidia SEGFAULT after start

You need to be able to disable the amdgpu at the UEFI/firmware hardware switch level. If you can't do that, disabling amdgpu will expectedly break if you try to work with an integrated screen.

Get rid of literally every xorg configuration, the environment override attempts and the module blacklists you've shown here (outside of nvidia_drm.modeset=1 on the kernel cmdline), what behavior are you getting in that case?

In the end, I didn't have the patience to fix it, so I reinstalled from scratch. I have more or less the same configuration, but everything works fine now.
