Downgrade Plasma 6.0.1 to Plasma 5.2.7

Plasma 6.0.1 is too laggy

That is guide how to downgrade:

sudo nano /etc/pacman.conf

#[core]
#Include = /etc/pacman.d/mirrorlist


#[extra]
#Include = /etc/pacman.d/mirrorlist

[core]
SigLevel = PackageRequired
Server=https://archive.archlinux.org/repos/2024/03/01/$repo/os/$arch

[extra]
SigLevel = PackageRequired
Server=https://archive.archlinux.org/repos/2024/03/01/$repo/os/$arch

Then

sudo pacman -Syyuu

If you have a problem with broken u need to downgrade each package manually with pacman -U.

 sudo pacman -Qi expat libelf lib32-expat lib32-libelf
 sudo pacman -U /var/cache/pacman/pkg/lib32-expat-2.6.0-1-x86_64.pkg.tar.zst
 sudo pacman -U /var/cache/pacman/pkg/lib32-libelf-0.190-1-x86_64.pkg.tar.zst

If you have problem with plasma-framework5 exists in filesystem

 sudo pacman -Syyuu  --overwrite '*'

The final step

sudo reboot
