On my Kubuntu Laptop (Gutsy), I tried to install a KDE4-environment within an chroot'ed debian, so that I can run two X11-servers parallel: one with native (productive) KDE3, and one with chroot'ed KDE4.

with help from http://wiki.debian.org/Kde4schroot I set up everything and started KDM4 into the chroot - so long.

BUT:
I my input-devices aren't working: mouse, keyboard aren't responding in this X11.
Xorg.1.log in the chroot'ed ENV says, I couln't found any input-devices... ?

Does anybody have experience, with setting up a parallel X11/KDE4 within chroot?

This is probably because the first X server has already claimed the input devices, making them unavailable to the second X. You could try the Xephyr method which was documented by the developer of KDE 4 Daily.

Thats, this solutions works better
But input is'n grabbed very well and "native" (alt+tab etc), as like as 3d-effects...

oKay, well - I found an unused partition on my laptop *surpise* and installed Intrepid with KDE 4.14 - very fine

Its not a real solution for this problem, but the best I can do at all to become more confident with kde4, its goodies and bugs
