LXDE Forums

Noob question here: I need to change a Debian KDE to a LXDE. Can someone here point me to a good guide? I have never change one before. Thanks.

I've never done that before and have done little more than play around with Debian. That said which version are you using? Do you want to remove all of the KDE (plus dependencies) or do you want to be able to choose which DE at boot? If the first is your choice then you may consider a re-install. If the second is your choice, check Synaptc. I believe that that LXDE was in there. An other option is the Debian forums. Someone may have done that and posted results there.

My hobby is after market LXDE desktops. It is very easy to do: .
Reboot and choose lxde or lxsession when prompted. You can also install lxde-core from Synaptic. If you do not intend to keep KDE, it is better to install a new operating system with lxde desktop. KDE is too bloated to remove easily. For more information read the introduction section of http://lxlinux.com/ and the aftermarket lxde guides found in the links therein.

from my own experience of installing new desktops i think its better to do a fresh install of the lxde edition of your distro or if it doesnt have one then install it right after you install your distro.

+1 rayzer (unless of course you want to be able to switch between the desktops).
