Hi Lourens
I would also suggest that you do "apt-cache search xfce4" and install all the xfce4 packages that look interesting to you.
I have done that.
When booting, my machines start in the console and I use startx to run XFCE4. This will only work if you, as your normal user, in your homedirectory, run/usr/bin/xfce4_setup This will do make all the required changes to your config files.
Ok, I have done that. But it also include -I think-, that I have to remove the gwm and kwm ?
Have fun
Erik JakobsenP.S. I made an reboot, but have not removed gwm and kwm, and the common boot window appearead after the boot.
