安装KDE

参考官方WIKI安装。 profile选择 default/linux/amd64/13.0/desktop/plasma，

emerge --ask xorg-server
env-update
source /etc/profile

emerge --ask x11-drivers/nvidia-drivers
nvidia-xconfig
eselect opengl set nvidia

emerge --ask x11-apps/mesa-progs
# 安装中文字体
emerge --ask wqy-microhei
emerge --ask emerge --ask kde-plasma/plasma-meta
sddm --example-config > /etc/sddm.conf

vim /etc/conf.d/xdm
#DISPLAYMANAGER="sddm"

rc-update add xdm default
/etc/init.d/xdm start

注意：需要添加用户，否则进去没有用户可以选，什么都干不了：

useradd -m -G users,wheel,audio -s /bin/bash larry

注意：貌似要安装一下的软件。记得不知为何，sddm登陆不上，直接运行startx命令即提示错误，安装后正常：

emerge --ask twm xterm xclock
