I haven't looked into it to find the issue. If I find the solution, I will ...

But sadly, I haven't yet find a way to make a backup copy of my customized Linux OS with all my favorite and necessary apps and settings. But I got a brief flashback of the horror that I used to go through earlier while installing Ubuntu as shown below: But thanks to Xubuntu, I don't have to face such horrors again. Even though, my habit of experimenting and to resurrect the buried ghost of Windows led me to this: Thankfully, my sanity returned and I decided to install only Xubuntu on my system. Also, I decided to follow the principle of automating and wrote a bash script to install my following favorite (and must have) apps on my newly installed system: vim - Text Editor for all my programming tasks and scripting gedit - Another Text Editor Docky - Dock Application vlc - Media Player smplayer - Another Media Player Deluge - BitTorrent Client Clem...
