After I install a new version of Linux, I usually take a good look at the screen. Does it have a task bar? Can I find my window after it was minimized? The direction some desktops are going is not clear. Making it easier for current users or for the people coming from Windows or Mac is not a goal anymore. User complains are dismissed, chalking it up to the fact that people don’t like change.
Fortunately, in Linux we have plenty of other choices, and we do like change. We have no need to keep using desktops we don’t like.
I will describe some of choices in this article, and I’ll attempt to measure the RAM memory requirements. I use free command in an xterm before and after the graphic environment is started on a separate X server (Xephyr). free command prints on the screen data made available by Linux kernel. The kernel knows at any moment how much memory is using and how many buffers are available.
