问题：

[rviz-3] process has died [pid 17193, exit code -6, cmd /opt/ros/melodic/lib/rviz/rviz -d /home/tagelyx/Desktop/tage_perception_visualiza_v3.1.3/src/perception_debug/launch/perception_debug.rviz __name:=rviz __log:=/home/tagelyx/.ros/log/091f3d3c-d5c2-11ec-addd-ccd9ac4d587d/rviz-3.log].
log file: /home/tagelyx/.ros/log/091f3d3c-d5c2-11ec-addd-ccd9ac4d587d/rviz-3*.log

运行以下五条命令

sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt-get update
sudo apt-get dist-upgrade
glxinfo | grep “OpenGL version”
sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntu-x-swat/updates

如果依然显示错误，运行
glxinfo | grep OpenGL查看自己OpenGL版本，我的版本显示
OpenGL version string: 1.4 Mesa 20.0.8
所以是OpenGL版本是mesa导致rviz启动不了。这时需要关闭硬件加速器。运行
export LIBGL_ALWAYS_SOFTWARE=1
然后再次启动rviz就可以了
