Process
This chapter show what process calls what.
init
init calls xdm
xdm
/etc/init.d/xdm sources /etc/sysconfig/displaymanager in the line
. /etc/sysconfig/displaymanager
xdm the X display manager calls kdm
kdm
kdm, the KDE display manager calls X and after login, startkde.
kdm log is in /var/log/kdm.log
start kdm manually: kdm /etc/opt/kde3/share/config/kdm/kdmrc
kdm's possible session types (KDE, GNOME etc) are defined in .desktop files in $KDEDIR/share/apps/kdm/sessions.
startkde
startkde calls ksmserver and hands over what Window manager it wants to have run. By default, it does not hand over anything and kwin is started as windows manager.
startkde log is in .xsession-errors
Working on
kded(2238) Kded::loadModule: Could not load library "kded_phononserver" . [ "The shared library was not found." ] I changed kded to output "Could not load2 library". did not work => there was a kded4 lying around in /usr/local/bin. This was drawn instead of my /usr/bin/kded4.
removed /usr/local/bin/kded4. Now I get
Kded::loadModule: Successfully loaded module "phononserver"
but KDE does not expect an input still. Did the same with kdeinit4, kde4-config, /usr/local/bin/kdeinit4_wrapper /usr/local/bin/kdeinit4_shutdown
TroubleShooting
This chapter makes proposals what to do if you cannot log in.
if it logs you out after logging in
- check if kdebase3-kdm is installed
- check /var/run/kdm.pid is there when kdm is running
- (re)-install all of kdebase-kdm, kdebase, kdelibs
- re-install xkeyboard-config
- check /usr/X11R6/lib/X11/xkb exists
- CTRL_ALT_F1 has to work
- /etc/X11/xdm/xdm-pid has to exist
working xorg.conf
staerk@staerk-desktop:~$ cat /etc/X11/xorg.conf
