Xorg upgrade troubles

[Žáček Kryštof <Krystof.Zacek@i.cz>]

Well, this transition could have been prepared better - testing stuff in such state on human beings is not ethical.

X did not start
==========
The symbolic link /etc/X11/X was wrongly set to /bin/true
Should be set to /usr/bin/X11/Xorg

KDM did not start
=============
/etc/kde3/kdm/kdmrc contains wrong line:
ServerCmd=/usr/X11R6/bin/X    ... there is no such file

should be

ServerCmd=/usr/bin/X11/Xorg  or better  /etc/X11/X

Keyboard layout tool error
==========================
kxkb not working anymore

I had to install xkb-data

Some special keys do not work anymore
=====================================
Cannot switch to virtual consoles with Alt-Ctrl-F1

Dead keys (ˇ) do not work anymore (e.g. for characters like Ž)
