Changing Enlightenment Versions
As of Bodhi Linux 3.0.0 both the E19 and E17 desktops are supported on Bodhi Linux. To figure out which version of Enlightenment you are currently running open the Enlightenment about tool from Menu->Enlightenment->About You will see a window that looks like this with the version number listed in the upper right hand corner:
If you are currently using E19 and wish to change to E17 open a terminal and run the command:
sudo apt-get install bodhi-desktop-e17
sudo apt-get install bodhi-desktop
Please note that at this time you can only have one version of Enlightenment installed at a time. This means adding E17 removes E19 and vise-versa. After running either of the above commands log out and log back in to get to your new desktop.
