【错误记录/vnc】连接vncserver一片黑或者只有光标

错误详情

• 本体见【树莓派/入门】64位系统Manjaro-ARM-xfce试用(持续更新)
• 在Raspberry Pi 4B上使用manjaro-xfce aarch64系统
• 使用tigervnc的vncserver创建后连接，直接一片黑，此时未修改任何东西
• 查询一大堆资料后
• 修改xstartup为

  #!/bin/sh
  unset SESSION_MANAGER
  unset DBUS_SESSION_BUS_ADDRESS
  xrdb $HOME/.Xresources
  startxfce4 &
  

  后

玄学解决

• 将xstartup的内容修改为

  #!/bin/sh
  
  [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
  xsetroot -solid grey
  xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
  startxfce4 &
  

  再重启服务

  sudo systemctl restart vncserver
  

  或者kill掉再重新创建

  vncserver -list
  # 假设结果为:1
  vncserver -kill :1
  vncserver :1
  

  再连接(终于可以显示，虽然还有中文乱码)
