Hard Stare

Respinning Linux -- Linux as a tool for bringing Internet access to the socially-disadvantaged

I found this post interesting:

"Respinning Linux"

It led me to comment as follows...

Have you folks encountered LXLE? It's a special version of Lubuntu, the lightest-weight of the official Ubuntu remixes, optimised for older hardware.

Cinnamon is a lot less than ideal, because it uses a desktop compositor. This requires hardware OpenGL. If the graphics driver doesn't do this, it emulates it using a thing called "LLVMpipe". This process is slow & uses a lot of CPU bandwidth. This is true of all desktops based on GNOME 3 -- including Unity, Elementary OS, RHEL/CentOS "Gnome Classic", SolusOS's Consort, and more. All are based on Gtk 3.

In KDE, it is possible to disable the compositor, but it's still very heavyweight.

The mainstream desktops that do not need compositing at all are, in order of size (memory footprint), from largest to smallest:
* Maté
* Xfce
* LXDE

All are based on Gtk 2, which has now been replaced with Gtk 3.

Of these, LXDE is the lightest, but it is currently undergoing a merger with the Razor-Qt desktop to become LXQt. This may be larger & slower when finished -- it's too soon to tell.

However, of the 3, this means it has a brighter-looking future because it will be based on a current toolkit. Neither Maté nor Xfce have announced firm migration paths to Gtk 3 yet.
