Make sure set the gblobal frame in RVIZ2 to scan and see if it then appears. I'm pretty sure it's undr 'Global Options". That will at least confirm the scan data is there. If it is then, you are probably lacking the TFs needed transform the scan frame up to whatever frame was being used as the RVIZ2 global frame. Adding the TFs should get you there.
You tagged RVIS but this is actually RVIZ2 and there is a big difference.

tf is definitely there, that's the first issue I had

global options/fixed frame is set to 'laser_frame' after running
ros2 run tf2_ros static_transform_publisher 0 0 0 0 0 0 world laser_frame
cannot paste image for some reason

still no /scan data frames, while I can echo tons of data being generated on /scan topic
seems RVIZ2 is just broken, in ROS it was working without any additional steps
I am gonna scratch my sd-card with my working ROS1 system. I wasted enough time like that
thanks for your help anyway

Then other idea I have is to look at QOS settings. I've not had issues with laser and QOS with RVIZ2 but I had a lot of trouble getting a map to display in RVIZ2 that I eventually traced back to QOS issues.

all I found is this, but I am not sure what/how to check https://design.ros2.org/articles/qos.html

what I dont understand is that there is a :scan topic, and data are there, RVIZ should at least display data frames or at leas an error if the data format is incorrect

ok in the terminal I see an error saying Sensitivity is not supported, this used to work in ROS1 it says supported modes are Standard,Express,Boost how do I setup these modes in RVIZ ?
