I just installed pclinuxos-enlightenment.2010.12.
I'm afraid you're going to have problems from that installation, no matter what. It's not the desktop that's the problem, it's that the iso you installed from is so far out of date. Unless you already know how to do it, just updating it will be impossible. Even if you do know how, it is still an "iffy" proposition. If you want the e17 desktop, here's what I'd do in your shoes.
Download and install the latest LXDE mini
. (click on LXDE mini for the link) After installing it, open Synaptic. Click Reload, then Mark All Upgrades, then Apply. After that, find the task-enlightenment
package. Mark it for installation and install it, along with all other packages it shows as dependencies. You can then install the "whole ball of wax" if you want by doing a search for e17
and marking all packages you want (especially the themes). Then do a search for enlightenment
, and do the same.
After that, post back again with further questions. If you have the Places module on your e17 desktop, you can change it to open with any file manager you choose, as long as you have that file manager installed.
