After I install a new version of Linux, I usually take a good look at the screen. Does it have a task bar? Can you find your window after it was minimized? Lately, some developers have been struck by some sort of amnesia, brought on by the stress created by the mobile sector offerings. The direction they are going is not clear. Their desktops are not easier for the current Linux user or for the people coming from Windows or Mac. What makes it worse is the way 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. It is believed the kernel knows at any moment how much memory is using and how many buffers it has available.
