KikwebDgdBgCom - Blog - My XDM Theme

Вторник, 13 Февруари 2007 20:49:45

Unlike KDE and [GNOME], Xfce does not have a native session manager, so decided to try the native one for X server - XDM. It is no problem one uses KDM or GDM, bur they will be slower and uselessly RAM 'eating' (especially KDM which loads several QT libs on it`s start up). XDM is much more simple but still customizable that the two mentioned above. It appears as two inputs - one for user name and one for password and nothing more. Themeing is simple and here is what I did to my login screen:
Enable XDM
To enable the XDM (or other *DM in general) edit the following line in /etc/inittab. Set the runlevel to 4 (display manager)

# Default runlevel. (Do not set to 0 or 6)
id:4:initdefault:

This will invoke a Display Manager. Unfortunately the XDM does not start Xfce as default, so you need to tell the X which session to load. Do the following:
echo "/etc/X11/xinit/xinitrc.xfce">~/.xsession
Now one final touch to the /etc/X11/xdm/Xsession file - uncomment the following lines to execute ~/.xsession before first. Note that there is a CASE "$1" which expects a xdm choice for the session to be given; it must not be executed.

if [ -x $HOME/.xsession ]; then                                                                                              
        exec $HOME/.xsession $@                                                                                              
fi

Now we have a XDM switched on and user with Xfce session loading. It is time for customization to begin.
XDM holds all its startup and session files under /etc/X11/xdm, so it is easyto find (Smile)

. Adding background image to the XDM + Shutdown button
Here is how my scripts look-like. /etc/X11/xdm/Xsetup_0

#!/bin/sh

# Correct the path and/or use another command to display the
# image as a stretched background if you want to.
# /usr/X11R6/bin/xsetroot -background '#445E72'
# For solid color
/usr/local/sbin/xdmshutdown -geometry +1+1 &
echo $! > /var/run/xdmshutdown.pid
display -window root  /usr/X11R6/lib/X11/xdm/pixmaps/xdm-bg.png

Where /usr/X11R6/lib/X11/xdm/pixmaps/xdm-bg.png is a picture taken from Xfce-Look.org for example.
/etc/X11/xdm/Xstartup

#Remove the shutdown button - BUGGY!
pid=`cat /var/run/xdmshutdown.pid 2>/dev/null`                                                                              
test "$pid" && kill -9 $pid 2>/dev/null
# Register session
/usr/X11R6/bin/sessreg  -a -w "/var/log/wtmp" -u "/var/run/utmp" 
        -x "/etc/X11/xdm/Xservers" -l $DISPLAY -h "" $USER
