Every time the kernel wants to update, something essential breaks…
systemsettings5 would crash after latest update. Right click on icon and launch Global Themes would launch into Global Themes but clicking around, various sections will crash - like Colors, Fonts …
I have noticed switching between kernels sometimes corrects things. So I installed higher and lower kernels and started testing between them.
The newer kernels didn’t change anything. So when I rebooted to linux54 (the lowest I had), memtest86+ started running.
Something removed ALL my kernels.
Pressing shift before it could enter memtest86 got me to the grub commandline.
Kernel images should be in /boot.
root=(hd0,msdos1)
ls /boot
no kernel images.
Plug in majaro iso on usb to live boot.
Connect to wifi
F12 for command prompt
sudo manjaro-chroot -a
sudo pacman -Syyuu
mhwd-kernel -li
(shows linux54 is current - even though it was not in /boot folder??)
mhwd-kernel -i linux54
mhwd-kernel -i linux510
mhwd-kernel -i linux514
Ok, now boots but doesn’t get to login screen.
Hit Alt-F2 for commandline.
sudo nano /etc/sddm.conf.d/kde_settings.conf
Session=
User=
(both empty)
should have:
Session=plasma.desktop
User=username
… still wont boot.
can’t find an xorg.config file, so:
sudo nvidia-xconfig
(in logs: Failed to initialize the NVIDIA Kernel module)
nmcli c
nmcli -a c up wifi connection
sudo mhwd -a pci nonfree 0300
Can finally log back in again, System Settings still doesnt work
I’ve updated plasma:
yay plasma-desktop
yay plasma-workspace
yay plasma-framework
Also did this (which broke my theme completely and didnt fix System Settings):
sudo pacman -Scc
sudo pacman plasma dolphin konsole xdg-user-dirs packagekit-qt5 knewstuff

I don’t understand how to fix System Settings. When run from the commandline it just says:
[~]$ systemsettings5
