Suppose you’ve got an old PC - for arguments sake, assume a late 2000s PC with only 2GB RAM - which DE would you choose?
Note that whilst a simple WM + some lightweight apps might be a better option, to keep things simple, I’m limiting this poll to just DEs - and too ones which are still being maintained.
Also, in case you’ve voted for a non-obvious/“other” option, I’m curious to hear about your experiences on running that DE on an old machine - and why you’ve selected it over the more obvious choices.
Enlightenment is easily the lightest full DE. It is my recommendation.
