Installing kde 4.2 beta

First you have to enable ppa lauchpad repository Neon nightly by doing the following instruction

deb http://ppa.launchpad.net/project-neon/ubuntu intrepid main
and sudo apt-get update && sudo apt-get install kde-nightly

It does not affect your existing kde installation. You can start it like another desktop session from your login manager window.

Issues I am facing:
1. Dolphin menu has no text all says No text.

2. gtk applications look ugly as its not setting the correct gtk rc files.
UPDATE 1: There is a script in .kde/env copy that to .kde-neon/env to fix gtkrc problem

3. kopete is not connecting to gmail as it can't find qca ossl plugin
UPDATE 2: to fix this we need to copy qca ossl plugin to qt plugin path of kde 4.2 beta.
Do sudo cp -r /usr/lib/qt4/plugins/crypto/ /opt/kde-nightly/lib/kde4/plugins/

4. After locking screen you cannot unlock it as its not accepting any password.

5. And random plasma crashes.

Well its the first beta release and I am pretty much sure kde folks will fix these when they release the final version
