小车按键没反应前进后退左右转都没有反应网络能ping通

wanghuan@wanghuan-virtual-machine:~/桌面$ ros2 run teleop_twist_keyboard teleop_twist_keyboard

This node takes keypresses from the keyboard and publishes them
as Twist/TwistStamped messages. It works best with a US keyboard layout.
---------------------------
Moving around:
  u    i    o
  j    k    l
  m    ,    .

For Holonomic mode (strafing), hold down the shift key:
---------------------------
  U    I    O
  J    K    L
  M    <    >

t : up (+z)
b : down (-z)

anything else : stop

q/z : increase/decrease max speeds by 10%
w/x : increase/decrease only linear speed by 10%
e/c : increase/decrease only angular speed by 10%

CTRL-C to quit

前面的键盘控制功能都是好的，但是启动rviz2时报错，启动界面闪退，请问下是什么原因？

sszb-wan@sszb-2:/mnt/c/WINDOWS/system32$ rviz2
QStandardPaths: wrong permissions on runtime directory /run/user/1000/, 0755 instead of 0700
Segmentation fault (core dumped)

@591259845 哈喽，问一下解决办法

@1117 用wsl需要安装linux GUI应用

小鱼，请问在执行这条运行agent的指令时：sudo docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged --net=host microros/micro-ros-agent:$ROS_DISTRO udp4 --port 8888 -v6，请问这个micro-ros-agent镜像是通过docker在线下载并运行的，还是之前就已经下载好的镜像然后通过docker运行下而已？一直没看懂这个agent镜像怎么来的，如果在线的方式的仅仅通过microros/micro-ros-agent这个镜像名就可以定位到这个吗？这个是通用的官方文件是吧？？

小鱼

@pst 有一个网站叫 docker hub
