Well it is not as close as running a whole kde4 installation or a kde4 livecd but it allows you to test it thouroughfully and this includes opengl effects. This is the way I chose, I created an unstable chroot and configured the kde3 kdm to run on display :1, while kde4 kdm will run on :0. This is because I can only run one xorg instance with opengl acceleration. I also use a test user for kde4 while my original debian-kde installation is untouched. These are some indications I went through to get this working. 1- create a chroot using debootstrap on /home/chroot/experimental 2- configure schroot to use that installation and also mount /tmp and /home (into chroot) 3- add the experimental repository to the chroot 4- apt-pin experimental packages with higher priority than unstable 5- install kdebase, kdemultimedia, kdeutils, kdegraphics, kdenetwork and kde-l10n-es 6- tweak the xorg configuration file to enable composite and dri. (into original installation) 7- change kde3 kdm configuration to reserve :1 instead of :0 8- create a test user and add it to audio group. Now each time you want to enter kde4: 1- Go to a text terminal 2- stop kde3 kdm 3- enter into the chroot 4- start kde4 kdm 5- Logon as test user 6- Go to another text terminal 7- Start kde3 kdm 8- Logon as regular user. This last steps could be cumbersome, but it could be automated using scripts. I planned to write a good explanation on the debian wiki, but I haven't found the time yet. More info on request.
