KDE Startup Sequence
Always runs as root! Uses
$ and
KDEDIR/share/config/kdmrc/etc/X11/xdm/Xservers. The latter contains entries
like:
:0 local /usr/X11R6/bin/X :0 vt07
Relevant startup files are also:
[X-*-Core] section in kdmrc
|
Setup - /etc/X11/xdm/Xsetup
|
| User enters username & password |
Startup - /etc/X11/xdm/Xstartup - prepare as root
|
Session - /etc/X11/xdm/Xsession - starts session as user
|
| = For a KDE session: kde or startkde |
= If present ~/.xsession or ~/.xinitrc
|
Reset - /etc/X11/xdm/Xreset - after session finished
|
The KDE startup sequence starts with the
startkde script. In most cases this script gets called
from the display manager (kdm) once the user has been authenticated. Their
are two very important lines in the startkde
script:
LD_BIND_NOW=true kdeinit4 +kcminit_startup and kwrapper4 ksmserver $KDEWM
The first line starts the kdeinit4 master process.
The kdeinit4 master process is used to start all other
KDE processes. It show up in the output of ps
aux as kdeinit4:
Running.... The arguments after kdeinit4
are the names of additional processes to be started. The +
indicates that kdeinit4 needs to wait till the process has
finished. kdeinit4 also starts
klauncher and kded.
The second of the two lines asks kdeinit4 to start the ksmserver session manager process. The session manager determines the lifetime of the session. When this process exits, the user is logged out.
