Re: [STUMP] StumpWM fails to initialize: asynchronous error & echo-string-list

[Joram Schrijver]

Hi,

The error has something to do with fonts. The response from the X server
to querying for the font is in a format CLX doesn't understand, so it
signals an error. Then StumpWM tries to display the error, but it needs
an instance of `screen` for that, which failed to initialize due to the
error.

The font it's trying to load is called "Gentium", which is odd. The font
opened at that stage should always be "9x15", which is a hardcoded
constant (+DEFAULT-FONT-NAME+), or "*" if "9x15" doesn't exist. This
suggests you're using a modified version of the StumpWM code, which is
causing this problem.

The problem with the Gentium font is probably that it's a truetype font,
returned by the X server in a format that's not supported by CLX. I'd
suggest leaving +DEFAULT-FONT-NAME+ alone and using SET-FONT to switch
to the font you want from your ~/.stumpwmrc. For truetype fonts,  use
the ttf-fonts contrib module. Do note that font rendering performance
with it is much worse than with legacy fonts.

Documentation for the ttf-fonts module is rather... lacking. The basic
steps are:

- Load the module
- Run (xft:cache-fonts)
- Use (xft:get-font-families) and (xft:get-font-subfamilies family-name)
to find the names for the font you want
- Call (set-font (make-instance 'xft:font :family family-name :subfamily
subfamily-name :size some-size))

You don't have to call xft:cache-fonts every time, because it caches the
results in ~/.fonts/font-cache.sexp.
