Thanks for the suggestions. ~/.fontconfig did not exist;
/var/cache/fontconfig was owned and writeable by me. Just to be sure, I
copied files into that directory successfully. I rebooted to safe mode
and ran "rm -rf /var/cache/fontconfig" (successfully, with no errors).
Still at the command window with nothing else running, I ran "fc-cache
--really-force --verbose" (sorry for the long lines):
<snip>
fc-cache had created /var/cache/fontconfig, owned and writeable (0755)
by me (again verified by copying files into the directory successfully).
It sure seems like slow XFT is a symptom of some other underlying
problem; what else can I do to diagnose?
I'm grasping at straws now, but... maybe a postinstall script failed
to run. You could try running font-update.
You should be able to see the names of the cache files that fontconfig
is creating if you do
$ FC_DEBUG=16 fc-cache -r -v
Maybe that will give a clue to the problem. Other FC_DEBUG values are:
MATCH 1 Brief information about font matching
MATCHV 2 Extensive font matching information
EDIT 4 Monitor match/test/edit execution
FONTSET 8 Track loading of font information at startup
CACHE 16 Watch cache files being written
CACHEV 32 Extensive cache file writing information
PARSE 64 (no longer in use)
SCAN 128 Watch font files being scanned to build caches
SCANV 256 Verbose font file scanning information
MEMORY 512 Monitor fontconfig memory usage
CONFIG 1024 Monitor which config files are loaded
LANGSET 2048 Dump char sets used to construct lang values
OBJTYPES 4096 Display message when value typechecks fail
Add the value of the desired debug levels together and assign that (in
base 10) to the FC_DEBUG environment variable before running the
application. Output from these statements is sent to stdout.
Fontconfig will distrust its cache files if the timestamps don't make
proper sense (it uses the timestamps to keep track of whether the
caches are up-to-date). Is there anything fishy there (like somehow
/var/cache has a modification time way in the future)?
Otherwise, you should use setup to download the source package for
fontconfig and build a debug version of fc-cache and try to figure out
where things are going wrong.
