I looked at the layout (in /usr/share/lyx/layouts) and found the head of "g-brief-de" as follows:
#% Do not delete he line below; configure depends on this # \DeclareLaTeXClass[g-brief]{letter (g-brief, german)} # Letter textclass definition file. # Author : Thomas Hartkens <[EMAIL PROTECTED]> # Input general definitions # Input stdletter.inc Do I need to uncomment the line # Input stdletter.inc ? I tried another template (hollywood) but got the same error message. Is this a debian problem or a configuration problem? I once set the default text class to a different class than article and maybe that's why I have this problem. Is there a way to reset all default values concerning textclasses? Thanks for your help Holger
