这些补丁其实有一段时间了，但我们这个版块提的人不多。我就打了几个包并附上补丁方便大家安装使用，论坛附件容量太小，我把它们放在我的 google page 上，欢迎大家下载测试：

David Turner's LCD ClearType-like patches and packages for Debian Sid
by quanliking

Update: 2006-08-24

Notice: These patches will dramaticly improve your LCD's font rendering capibility. But the Author David Turner is still too unsure of the patent situation regarding this technology to do that now.

11. Satify the dependances:
13. $ sudo apt-get install build-essential devscripts fakeroot
14. $ sudo apt-get build-dep libcairo2 libxft2 freetype

复制代码

2. 2. patch libxft2 and build package
4. $ mkdir libxft2 && libxft2
5. $ apt-get source libxft2
6. $ cd xft-2.1.8.2
9. $ dch -i
10. something like below：

32. $ dpkg-source -x freetype_2.2.1-2.dsc
35. $ cd freetype-2.2.1
37. $ dch -i
38.   * Disable quantization when subpixel is on
39. $ dpkg-buildpackage -rfakeroot -us -uc
42. $ cp ../libfreetype6_2.2.1-3_i386.deb ../../debs/
43. $ cp ../libfreetype6-dev_2.2.1-3_i386.deb ../../debs/

复制代码

2. Install the patched packages：
4. $ cd cleartype/debs
5. $ dpkg -i *.deb

复制代码

Last step and it is important if you want to get the beautiful fonts:

run gnome Font Preferences, goto Detail panel:

linuxcpp

如何hold住这几个包

2. #dpkg --set-selections
3. libfreetype6 hold
4. libfreetype6-dev hold
5. libxft2  hold
6. libcairo2  hold

复制代码

Ctrl + d
退出
这样升级系统时就不会升级这几个包

我用的ubuntu 6.06，打上这个补丁后ctrl+Backspace重新启动X，但是没有效果，请问为什么阿？我之前完全参照搂主那个用xp字体美化界面的贴子设置了一下界面，有影响吗？

请问楼主：

$ mkdir cleartype && cd cleartype
$ mkdir patch debs

mkdir执行时是在哪个目录下？
