PROBLEM

Not clear, but looks like misconfigured packages after multiple installations, uninstallations and re-installations of packages and Desktop Environments

PROLOGUE

So today I had problems that caused KDE Plasma to not acknowledge my laptop as a laptop. In other words, my Arch was on the edge of collapse.

BABY STEPS

So, I tried reinstalling all the packages of my installation in one command, like so

# pacman -Qenq | sudo pacman -S -

But as you can see the post hasn’t ended here, it didn’t pan out.

SOLUTION

After hours of help at #archlinux and #kde-plasma, I found this Forum page that gave me just the right instructions!

1. First up, I removed all the orphaned/unused packages rotting away in my system.

   # pacman -Rns $(pacman -Qtdq)
   

2. next, I force-reinstalled all the packages I had in my installation.

   # pacman -Qqen > pkglist.txt
   # pacman --force -S $(< pkglist.txt)
   

EPILOGUE

Now my installation is sweet as candy with no loss of any personal configs, and everything is perfect again!
