https://linuxtyper.wordpress.com/2012/06/07/what-window-manager-should-i-use-part-5-icewm-and-conclusion/. There is an interesting discussion in five parts that is discussing what window manager is the best for your Linux desktop. I am using KDE 4.8.3 with the Metacity window manager. I got sick of using Compiz and I prefer the Metacity window manager instead. KDE 4.8.3 on Linux Mint 13 Maya is very fast and stable indeed. The Unity desktop and other bugs are killing the Ubuntu Linux distribution, but the Linux Mint 13 distribution is still going. So all I can say is just use KDE. You will thank me for that. Type metacity –replace &exit in a terminal window and it will switch to the Metacity window manager instead of Compiz or Kwin.
The Android 4.0 Gingerbread interface is also very nice to use once you get used to using it. Linux needs a worthwhile desktop interface, the Unity desktop is too slow and buggy to be something that we want to showcase as the main Linux desktop in Ubuntu. Bring out something better Canonical! The Ubuntu distribution is embarrassing, if it is to be using the tablet interface as the default desktop, then at least make a distribution that is not as embarrassing as it is today. I tried Ubuntu 11.10 on a netbook, but replaced it with Android 4.0. That is far faster and fun to use as well.
