Just as a sidenote Mate desktop is a continuation of the gnome2 code, so it is actively supported and developed

Thank you, Mike Cammilleri, for bringing this up. I am also very keen to have more information on this topic. I think it worthwhile to mention a few things. On the site http://www.x.org/wiki/Development/Documentation/Performance/ the topic of acceleration is discussed and there is mentioned an older form of acceleration named XAA and a newer form named EXA. The relevance for our discussion is that some graphic card chipsets in older pcs won't work with EXA unless we abandon the usual xorg driver and use the basic one called vesa. This results in slower performance and without some features provided by the non-vesa drivers. Versions of xorg.core from 1.13 onwards no longer have XAA which did work with these chipsets. This issue is present in all Linux distros. Two are Ubuntu and Debian which I am following. In Ubuntu 12.04 xorg.core is at version 1.11 and so has XAA and these older graphic cards still work without resorting to downgrading the driver used to vesa. Debian Wheezy (stable) uses xorg.core 1.12 and also has XAA. Ubuntu 14.04 and Debian Jessie (testing) use newer versions of xorg.core and don't have XAA so these older chipsets only work with vesa. Completely separate is the choice of desktop. My preference is lxde and others much more knowledgeable than myself here in Greece prefer gnome-fallback (gnome-flashback in some distros.) A site mentioning this is http://en.wikipedia.org/wiki/Controversy_over_GNOME_3 where mate is also mentioned. My two cents on this is that because mate is using gnome2 code which is no longer actively developed while gnome-fallback is using gnome3 code which is may be an important difference. Last point (sorry for length) is that Alkis Georgopoulos and the others in the technical support team here in Greece who have been developing and improving the use of ltsp for about 8? years now and have more than 400 state run schools using ltsp have said that the choice of gnome-fallback was more about it using metacity while unity introduced in Ubuntu 12.04 was only using compiz. Later versions of unity have the adaptability to use metacity but compiz is its default. Since these Greek schools (and so many others) had already adapted to gnome2, gnome-fallback provides a no-brainer ease of use since it so closely resembles gnome2 on the surface. Also, they said that while lxde is even lighter (it uses openbox, not compiz or metacity) the main performance drag with ltsp is the use of heavy apps like firefox and libreoffice.
