Frederic:
Out of curiousity, do you have a valid value set in the GDM configuration for GtkRC. If this is set to a valid value, it mightwhile investigating Mandriva bug http://qa.mandriva.com/show_bug.cgi?id=29870 and reading gdm code, it seems font size is never set in graphical greeter when not specified in theme, since it defaults to "Sans", see greeter_parser.c:1435 and according to pango_font_description_from_string API documentation, resulting information will give a font size of 0. And when do_font_size_reduction is called after, it still sets font size to 0. Shouldn't we enforce a default font size ? 10 or 12 maybe ?affect how fonts look. The problem may be you have it set to an invalid file?I've asked original reporter for more informations about this bug and problem has been fixed, so it may have been caused by a incorrect GtkTheme key. I tried to duplicate but I couldn't.
I'm a bit uncomfortable trying to fix a bug that can't be replicated.
If that doesn't fix the problem, I'd be happy to accept a patch to default to a reasonable fontsize.I've discussed with Bedhad about this and he suggested to use gtkwidget default font description and merge the property from the theme using pango_font_description_merge. WDYT ?
I'd be agreeable to accepting a patch to set the default font/font size. Perhaps it would make sense to make such a thing configurable rather than hardcoding it in the c-code. Brian
