From: Stephen Berman <stephen.berman <at> gmx.net> To: emacs-pretest-bug <at> gnu.org Subject: 23.0.60; X protocol error: BadFont Date: Sat, 24 Jan 2009 14:17:35 +0100
When I start Emacs like this: emacs -Q --daemon --eval "(setq default-frame-alist '((font-backend . \"xft\") (font . \"Dejavu Sans Mono-10\")))" and then invoke emacsclient -c the frame that appears displays the font Dejavu Sans Mono-10 with antialiasing. This is the same result as starting Emacs like this: emacs -Q -xrm 'Emacs.FontBackend: xft' -fn "Dejavu Sans Mono-10" (exept that here there is no daemon; as I learned, the --daemon option is incompatible with X11 options). But when I start Emacs like this: emacs -Q --eval "(setq default-frame-alist '((font-backend . \"xft\") (font . \"Dejavu Sans Mono-10\")))" & which differs from the first invocation above only in lacking `--daemon' and being backgrounded, the frame that appears has tiny illegible characters, the shell beeps and prints this: steve <at> escher:~> libxcb: WARNING! Program tries to lock an already locked connection, which indicates a programming error. There will be no further warnings about this issue. and emacs consumes 100% of CPU and can only be killed with -9. (If I don't use `&', then the frame immediately closes and the Emacs process is killed.) I repeated this under gdb, following the etc/DEBUG instructions for debugging X protocal errors, and got the backtrace below: steve <at> escher:~/lib/emacs-cvs-gtk/src> gdb ./emacs GNU gdb (GDB; openSUSE 11.1) 6.8.50.20081120-cvs Copyright (C) 2008 Free Software Foundation, Inc.

It's the font-backend parameter-value pair alone that causes this, i.e., instead of the above, it sufficient (and necessary) to do this: emacs -Q --eval "(setq default-frame-alist '((font-backend . \"xft\")))" & Likewise, if I make ~/.emacs consist of this: (setq default-frame-alist '((font-backend . "xft"))) then after invoking `emacs' the same thing happens as above, and in addition the shell shows the following: (emacs:11144): GLib-WARNING **: g_main_context_prepare() called recursively from within a source's check() or prepare() member. -- Steve Berman
