I think the closer way to the real thing(TM) for using kde4 and keeping your
kde3 installation untouched is creating a chroot. 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.
