WARNING! PLEASE DO NOT THINK THIS IS BUG PROOF!
To use E17 as the window manager of KDE4 is actually very simple
1. Install Task-Enlightenment from Synaptic
2. Log in to E17 and set it up the way you want it
3. Open Konqueror - Super User Mode and go to etc/profile
4. find the part of the document that says this:
# some old programs still use it (eg: "man"), and it is also
# required for level1 compliance for LI18NUX2000
NLSPATH=/usr/share/locale/%l/%N
export PATH PS1 USER LOGNAME MAIL HOSTNAME INPUTRC NLSPATH
export HISTCONTROL HISTSIZE
5. Change that to:
# some old programs still use it (eg: "man"), and it is also
# required for level1 compliance for LI18NUX2000
NLSPATH=/usr/share/locale/%l/%N
KDEWM=enlightenment_start
export PATH PS1 USER LOGNAME MAIL HOSTNAME INPUTRC NLSPATH KDEWM
export HISTCONTROL HISTSIZE
6. Save that file and log out.
7. It's done! now just log back into KDE and play around. To go back to using KWIN just remove the lines we added and it will go back to normal.
