Last week I updated my whole system. And after that I was unable to login to my KDE Plasma Desktop. Please note that I am working on Arch Linux on a 32 bit laptop. So I posted a topic in this regard in Arch Linux forum which can be seen at here. But till date I have not found solution this problem. I am being suggested to downgrade my Arch Linux version or using a 64 bit system. But at this moment neither of them is possible. So alternatively I am using Xfce Desktop Environment and I feel proud to say that this is really an excellent lightweight desktop environment. However still I am waiting for solution of KDE Plasma on 32 bit systems in Arch Linux. Let us see what happens.
