设置xorg.conf后使用sddm启动不一定能启动桌面，设置另一配置文档,

//修改startx或DM的启动脚本
//用的DM是SDDM，需要修改/usr/share/sddm/scripts/Xsetup文件，在该文件末尾添加以下内容：
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

//如果用的是startx，在~/.xinitrc中启动DE或WM的命令之前添加

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
