1,准备好信心和耐心，这点很重要哦。
2,找个快的源，pacman -Syu ，其实我一开始也想光升级xorg的，但是后来想想整个系统的升级吧，这样应该成功的可能性更大一点，也是最偷懒的办法。个别的实在不想升级的包（比如我的mysql和apache，php）可以放到pacman.conf的Ignore里面。
如果你也和我一样用nvidia驱动，强行卸掉libgl-dri。
3,安装字体：
引用:[root@Ina ~]# pacman -Ss xorg | grep font
current/xorg-font-utils 1.0.0-1
X.Org font utilities
current/xorg-fonts-100dpi 1.0.0-2
X.org 100dpi fonts
current/xorg-fonts-75dpi 1.0.0-2
X.org 75dpi fonts
current/xorg-fonts-alias 1.0.1-1
X.org font alias files
current/xorg-fonts-cyrillic 1.0.0-1
X.org cyrillic fonts
current/xorg-fonts-encodings 1.0.0-1
X.org font encoding files
current/xorg-fonts-misc 1.0.0-2
X.org misc fonts
current/xorg-fonts-type1 1.0.0-2
X.org Type1 fonts
X.Org X11 xfs font server
这些都装上吧，呵呵。
4,真对xorg.conf开工。
搞定滚轮和fcitx。
整理Section "Files"部分：
更改ModulePath为："/usr/lib/xorg/modules"。
更改RgbPath为："/usr/share/X11/rgb"。
注释掉原来字体的路径，增加：
引用:FontPath "/usr/share/fonts/misc"
FontPath "/usr/share/fonts/75dpi"
FontPath "/usr/share/fonts/100dpi"
FontPath "/usr/share/fonts/TTF"
FontPath "/usr/share/fonts/Type1"
FontPath "/usr/share/fonts/wqy"
如果你有自己的字体，也一起加上。
最后，如果你和我一样使用wqy-bitmap，要改一下/etc/fonts/conf.d/里面的连接：
ln -s yes-bitmaps.conf 10-bitmaps.conf
启动x试试，是不是好了很多？
