将Ubuntu Edgy 内 Xorg 升级至 7.2
Xorg 7.2 稳定版已经发布。本文提供了如何在Ubuntu Edgy环境下快速升级以及恢复的方法。
一、如何升级
修改 sources.list 文件，加入以下内容：
# Treviño's Ubuntu edgy Xorg-7.2 Repository (GPG key: 81836EBF - DD800CD9)
deb http://download.tuxfamily.org/3v1deb edgy xorg-7.2
更新源：
apt-get update
接着你可以用喜欢的方式更新软件包，比如新立德、apt-get upgrade。
更新完成后，重启启动X即可使用。
若上文提供源无法使用，您可以在这里获取更多的源地址。
二、如何恢复至Edgy默认版本
去除 sources.list 中添加的源地址。执行
apt-get update
sudo apt-get install libgl1-mesa-dev/edgy libgl1-mesa-dri/edgy libgl1-mesa-glx/edgy libgl1-mesa-swx11/edgy libgl1-mesa-swx11-dbg/edgy libgl1-mesa-swx11-dev/edgy libglu1-mesa/edgy libglu1-mesa-dev/edgy libosmesa6/edgy libosmesa6-dev/edgy mesa-common-dev/edgy mesa-swx11-source/edgy mesa-utils/edgy x11-common/edgy x11proto-damage-dev/edgy x11proto-gl-dev/edgy x11proto-input-dev/edgy x11proto-randr-dev/edgy xbase-clients/edgy xdmx/edgy xdmx-tools/edgy xkb-data/edgy xkeyboard-config/edgy xlibmesa-dri/edgy xlibmesa-gl/edgy xlibmesa-glu/edgy xlibs-dev/edgy xlibs-static-dev/edgy xnest/edgy xorg/edgy xserver-xephyr/edgy xserver-xorg/edgy xserver-xorg-core/edgy xserver-xorg-dev/edgy xserver-xorg-input-acecad/edgy xserver-xorg-input-aiptek/edgy xserver-xorg-input-all/edgy xserver-xorg-input-digitaledge/edgy xserver-xorg-input-elographics/edgy xserver-xorg-input-fpit/edgy xserver-xorg-input-hyperpen/edgy xserver-xorg-input-kbd/edgy xserver-xorg-input-magellan/edgy xserver-xorg-input-mouse/edgy xserver-xorg-input-mutouch/edgy xserver-xorg-input-palmax/edgy xserver-xorg-input-spaceorb/edgy xserver-xorg-input-summa/edgy xserver-xorg-input-synaptics/edgy xserver-xorg-input-tek4957/edgy xserver-xorg-input-void/edgy xserver-xorg-input-wacom/edgy xserver-xorg-video-all/edgy xserver-xorg-video-apm/edgy xserver-xorg-video-ark/edgy xserver-xorg-video-ati/edgy xserver-xorg-video-ati/edgy xserver-xorg-video-chips/edgy xserver-xorg-video-cirrus/edgy xserver-xorg-video-cyrix/edgy xserver-xorg-video-dummy/edgy xserver-xorg-video-fbdev/edgy xserver-xorg-video-glint/edgy xserver-xorg-video-i128/edgy xserver-xorg-video-i740/edgy xserver-xorg-video-i810/edgy xserver-xorg-video-imstt/edgy xserver-xorg-video-mga/edgy xserver-xorg-video-neomagic/edgy xserver-xorg-video-newport/edgy xserver-xorg-video-nv/edgy xserver-xorg-video-rendition/edgy xserver-xorg-video-s3/edgy xserver-xorg-video-s3virge/edgy xserver-xorg-video-savage/edgy xserver-xorg-video-siliconmotion/edgy xserver-xorg-video-sis/edgy xserver-xorg-video-sisusb/edgy xserver-xorg-video-tdfx/edgy xserver-xorg-video-tga/edgy xserver-xorg-video-trident/edgy xserver-xorg-video-tseng/edgy xserver-xorg-video-v4l/edgy xserver-xorg-video-vesa/edgy xserver-xorg-video-vga/edgy xserver-xorg-video-vmware/edgy xserver-xorg-video-voodoo/edgy xutils/edgy xvfb/edgy x-window-system/edgy x-window-system-core/edgy
