Gnus/5.13 (Gnus v5.13) Emacs/23.0.60 (gnu/linux) |
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@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:
