現在的 fontconfig 多了兩目錄以增加設定的彈性, 見 /etc/fonts :
conf.d {啟用的設定檔}
conf.avail {全部可用的設定檔}
其中 conf.d 的內容多是 conf.avail 的 soft link, 連結了就代表啟用, 刪掉了連結就是停用, 方便吧 ?! 更多關於 conf.d 設定檔的說明可以查看 /etc/fonts/conf.avail/README
conf.d/README
Each file in this directory is a fontconfig configuration file. Fontconfig
scans this directory, loading all files of the form [0-9][0-9]*. These files
are normally installed in ../conf.avail and then symlinked here, allowing
them to be easily installed and then enabled/disabled by adjusting the
symlinks.
The files are loaded in numeric order, the structure of the configuration
has led to the following conventions in usage:
Files begining with: Contain:
00 through 09 Font directories
10 through 19 system rendering defaults (AA, etc)
10-autohint.conf
10-no-sub-pixel.conf
10-sub-pixel-bgr.conf
10-sub-pixel-rgb.conf
10-sub-pixel-vbgr.conf
10-sub-pixel-vrgb.conf
10-unhinted.conf
20 through 29 font rendering options
20-fix-globaladvance.conf
20-lohit-gujarati.conf
20-unhint-small-vera.conf
30 through 39 family substitution
30-urw-aliases.conf
30-amt-aliases.conf
40 through 49 generic identification, map family->generic
40-generic-id.conf
49-sansserif.conf
50 through 59 alternate config file loading
50-user.conf Load ~/.fonts.conf
51-local.conf Load local.conf
60 through 69 generic aliases
60-latin.conf
65-fonts-persian.conf
65-nonlatin.conf
69-unifont.conf
70 through 79 select font (adjust which fonts are available)
70-no-bitmaps.conf
70-yes-bitmaps.conf
80 through 89 match target="scan" (modify scanned patterns)
80-delicious.conf
90 through 98 font synthesis
90-synthetic.conf從 50-user.conf 及 51-local.conf 的說明得知, 固有的 ~/.fonts.conf 及 /etc/fonts/local.conf 設定檔還是有效的, 所以我 2004 年的那個設定檔也一直有效, Linux 真的很可愛呢 :)
新的設定 "借用" 了 ubuntu 的設定檔, 所以很快便完成了更新。下面貼上我的 local.conf 內容, 留意套用前需確保安裝了以下字型 :
opendesktop-fonts

</fontconfig>下面是兩張前后比較圖, 首先是舊版的 fireflysung :
然后是 opendesktop-fonts 的效果 :
新版的 opendesktop-fonts 字體橫了, 不像以往的瘦瘦高高, 現在是方方正正, 更像新細明體。而DejaVu 就沒有看出那裡跟 Bitstream 不一樣 :P
Linux 字型設定是比較深入的技巧, 沒有經過 2003-2004 或更早的中文設定的磨練過的話可能會較難上手, 所以希望下次再由理論開始講講。
