[edit] Running KDE inside a window using Xnest
For KDE you need a to make the file: .xinitrc-kde in your home directory that contains the following:
#!/bin/sh
exec /usr/kde/3.4/bin/startkde
Note that you may need to change the location of startkde
To find the location of startkde you can simply:
slocate */bin/startkde
To start a new kde session inside of a 1024x768 window simply issue the following command:
xinit ~/.xinitrc-kde -- `which Xnest` :5 -geometry 1024x768
TIP: su to a different user before running the command to run KDE as that user, but remeber to copy the .xinitrc-kde file to the users home you wish to login as.
cp ~/.xinitrc-kde /home/USER
su USER
xinit ~/.xinitrc-kde -- `which Xnest` :5 -geometry 1024x768
[edit] Making an Alias
To make an alias add the following to ~/.bashrc (per user alias) or /etc/bashrc (Globaly):
alias nestkde="xinit ~/.xinitrc-kde -- `which Xnest` :5 -geometry 1024x768"
Then to make the alias active (with out restarting bash)
source ~/.bashrc OR source /etc/bashrc
now all you have to do is run nestkde and up will pop KDE in a 1024x768 window.
for full alias information visit: TIP_alias
[edit] Displays
The default X server ":0" will be in use and therefore you will not be able to use it, thus we must use a display higher than that (and that is not in use) Also, if you want to be able to launch more than one Xnest session, each of these will need to have a different display number.
The -geometry argument tells Xnest the size of window you want.
If you get an error try using a different display :6 and so on.
