No fonts found; this probably means that 
the fontconfig
library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information
about 
fontconfig can be found in the fontconfig(3) manual
page and on http:
//fontconfig.org

Agent pid 4985 
killed
The application 'xfce-mcs-manager' lost its connection to the 
display :0.0;
most likely the X server was shut down or you 
killed/destroyed
the application.

The same mistakes pop up with icewm but not with the basic twm window-

What's wrong with my installation?
