@BJTUpupil Hello, Double check if ros-humble-ros-gzgarden is installed by running sudo apt install ros-humble-ros-gzgarden, If it did not work do the "Install ROS 2" part in readme again.
@monemati Hello, i run make px4_sitl gz_x500_depth have some problem, i got this:

Is it because of a problem with libEGL?
libEGL warning: egl: failed to create dri2 screen
Is it necessary to use an nvidia graphics card for rendering? The computer I use is a 4060+13700k notebook. I feel that it may be because the core graphics is always involved in the calculation. I have tried to fix this problem for several days, but to no avail. success
@BJTUpupil Hi, the libEGL is only a warning. You are getting INFO [px4] Startup script returned successfully and it means px4 is ok, what is your problem? You can't see the gazebo world or something else?
