"Because some existing applications rely on seeing a collection of point and pixel sizes, server vendors are strongly encouraged in the near term to provide a mechanism for including, for each scalable font name, a set of specific derived instance names. For font sources that contain a set of specific derived instance names." So it is OK to have that in font list. It must be --0-0- base name for every such font, and if it is not -- there is an error somewhere in your X server or font server, and probably should be fixed. If there are base entries -- then you don't need them. </pre> </blockquote> <pre class="moz-quote-pre" wrap=""> [skipped] </pre> <blockquote type="cite"> <pre class="moz-quote-pre" wrap=""> I don't really need it, existing choice is big enough ! </pre> </blockquote> <pre class="moz-quote-pre" wrap=""> Probably you somewhat misread my description.

The answer is at the end of chapter 5 of <a class="moz-txt-link-freetext" href="https://www.x.org/releases/X11R7.7/doc/xorg-docs/xlfd/xlfd.html#Scalable_Fonts">https://www.x.org/releases/X11R7.7/doc/xorg-docs/xlfd/xlfd.html#Scalable_Fonts</a> where it is said: "if the actual pattern argument (of ListFonts X query) has values containing no wildcards in scalable fields, then substitute each such field into the corresponding field in each scalable font name in the list." So as I understand, if we call xlsfonts -fn "-*-*-*-*-*-*-0-0-*-*-*-0-*-*" (Pixel size, point size and average width at 0), we get all scalable fonts, and if we call xlsfonts -fn "-*-*-*-*-*-*-0-138-*-*-*-*-*-*" (Pixel size at 0 and point size of 138) or xlsfonts -fn "-*-*-*-*-*-*-*-138-*-*-*-0-*-*" (Point size of 138 and average size at 0), we get all scalable font instances with a point size of 138 and some default resolutions. 120 seems to be something like a default point size value and 17 a default pixel size when these values are not specified. try to call xlsfonts -fn "-*-*-*-*-*-*-0-*-*-*-*-*-*-*" or xlsfonts -fn "-*-*-*-*-*-*-*-0-*-*-*-*-*-*" I already thank you Ilya for your help and spoting to the XLFD doc that is not easy to find Lucien </body> </html>
