openEuler 24.03 LTS SP1安装XFCE图形界面 openEuler 24.03 LTS SP1安装XFCE图形界面XFCE是一款轻量级 Linux 桌面，当前版本已经将所有部件从 GTK2 更新到 GTK3，从D-Dbus Glib更新到GDBus，大部分组件支持GObject Introspection（简称 GI，用于产生与解析 C 程序库 API 元信息，以便于动态语言（或托管语言）绑定基于 C + GObject 的程序库）。优化用户体验，加入新特性，并修补大量BUG。与其它UI界面（GNOME、KDE）相比，XFCE占用的内存和CPU使用量非常小，给用户带来亲切和高效的使用体验。XFCE支持x86_64和aarch64两种架构。安装时，建议新建一个管理员用户。1.下载openEuler ISO镜像并安装系统，更新软件源（需要配置Everything源，以及EPOL源，下面命令是在最小化安装系统的情况下安装XFCE）sudo dnf update2.安装字库sudo dnf install dejavu-fonts liberation-fonts gnu-*-fonts google-*-fonts3.安装Xorgsudo dnf install xorg-*4.安装XFCE及组件sudo dnf install xfwm4 xfdesktop xfce4-* xfce4-*-plugin network-manager-applet5.安装登录管理器sudo dnf install lightdm lightdm-gtk6.设置默认桌面为XFCE 通过root权限用户设置echo 'user-session=xfce' >> /etc/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf7.使用登录管理器登录XFCEsudo systemctl start lightdm登录管理器启动后，在右上角左侧选择"xfce-session" 输入用户名、密码登录8.设置开机自启动图形界面sudo systemctl enable lightdm sudo systemctl set-default graphical.target9.如果默认安装了gdm，建议停用gdmsystemctl disable gdm10.重启验证sudo reboot避坑在安装过程中，提示找不到以下：xfwm4 xfdesktop xfce4-* 软件包。如果忽略继续安装，重启系统进入登录界面时会提示session错误原因是：在官方镜像源中以上软件包缺失。解决方法：修改镜像源为：#generic-repos is licensed under the Mulan PSL v2. #You can use this software according to the terms and conditions of the Mulan PSL v2. #You may obtain a copy of Mulan PSL v2 at: # http://license.coscl.org.cn/MulanPSL2 #THIS SOFTWARE IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR #IMPLIED, INCLUDING BUT NOT LIMITED TO NON-INFRINGEMENT, MERCHANTABILITY OR FIT FOR A PARTICULAR #PURPOSE. #See the Mulan PSL v2 for more details.
