Manjaro KDE freezing after enter login and password

root starts up properly, but chrome does not start in root, Add/Remove Software also fails to update packages, writes: Failed to synchronize AUR database and `Failed to build libkipi``. But the new user does not start in plasma mode (x11): a black screen appears for 3 seconds, after which it is suggested to enter the password again.

But Add/Remove software never worked on NVMe, I update packages through pamac and pacman.

Add/Remove Software stdout:

https://aur.manjaro.org/packages-meta-ext-v1.json.gz: Could not connect: Network is unreachable

Failed to build libkipi

Maybe I need reinstall plasma x11? :pensive:

I tried kernel version 54, same result.

navigate via dolphin to etc/x11 and check what .conf files do you have there, also check in the folders

All files in etc/X11:

nothing suspicious there, so navigate to etc/mkinitcpio.conf and edit the MODULES="" section to look like this:
MODULES=(nvidia nvidia_drm nvidia_uvm nvidia_modeset)
then run this command:
sudo mkinitcpio -P
reboot
if it doesnt work post output from: mhwd-kernel -l

I changed /etc/mkinitcpio.conf, after running the command, the image was successfully generated, but after restarting and entering the password, everything froze again.(

mhwd-kernel -l                                                                                                                                                                                                              
available kernels:

   * linux517
   * linux518
   * linux54
   * linux515-rt
   * linux516-rt
   * linux517-rt

so i dont know what it could be… try installing the latest 518 kernel:
sudo mhwd-kernel -i linux518
reboot, and boot into it and see

I try linux518 experimental, nothing has changed…
It looks like I’ll have to reinstall the system, very sad.

mhwd-kernel -li

well if you really are going for reinstall you could try resseting your plasma settings first, maybe it will help:

  1. Log out of KDE.
  2. Switch to TTY with CTRL + ALT + F2 - if f2 doesnt work, try f1-f6 instead
  3. Login in TTY with your username and password.
  4. Stop the Display Manager service:
sudo systemctl stop display-manager.service
  1. Run this command to reset the settings:

find $HOME/.config/ -maxdepth 1 -name 'plasma*' -exec rm {} \;

clear cache:
rm -rf ~/.cache/*

  1. reboot:
    systemctl reboot

find $HOME/.config/ -maxdepth 1 -name 'plasma*' - returns folders, so I ran your command with -r flag find $HOME/.config/ -maxdepth 1 -name 'plasma*' -exec rm -r {} \;.
And I cleared cache. My desktop has been reset, but login still not work.

then i dont know … you could try uninstalling plank, reboot

I deleted Plank via pacman, but everything remained the same…

One strange question does not leave me.
At the very beginning, when I first installed the system, login worked, but not always correctly. When login was incorrect, plasma was not turned on: I entered the password, there was a long loading with a progress bar, then a black screen, my cursor loaded, Plank loaded too. I clicked on the Konsole, which is located on my Plank, I usually performed a reboot, and my system booted properly. But yesterday I decided to enter the startx command in Plasma X11 in Konsole, as far as I understand startx launches Wayland. After entering the startx command, everything froze, I performed a hard reboot, through a button on my PC, and since then nothing has worked anymore. How did one command kill the work of the entire shell?

startx doesnt start wayland it starts xserver … and i dont know if startx is related to your issues… i just got an idea delete the .xauthority file from home, then reboot

There are several of them, delete only one? By the way, it was modified just when the problem occurred.

i have only one xauthority… so try deleting all of them and reboot… if it doesnt work we try to reinstall your graphics drivers

Wow! Thank you, we’ve been struggling with this for so long, and it finally worked! Now I need to restore my desktop! I am very happy, thank you very much!

so deleting the xauthority worked? … should think of it sooner, but at least its finally solved, and you dont have to reinstall …

Yes, I deleted three files and reboot, after login working correctly. A miracle!)
