vim /etc/systemd/system/vncserver@:1.service
接着我們用自己最喜歡的編輯器（這兒我們用的 nano ）打開 /etc/systemd/system/vncserver@:1.service ，找到下面這幾行，用自己的用戶名替換掉 。舉例來說，我的用戶名是 linoxide 所以我用 linoxide 來替換掉 ：
ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
PIDFile=/home/<USER>/.vnc/%H%i.pid
替換成
ExecStart=/sbin/runuser -l linoxide -c "/usr/bin/vncserver %i"
PIDFile=/home/linoxide/.vnc/%H%i.pid
如果是 root 用戶則
ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"
PIDFile=/root/.vnc/%H%i.pid
