Since I am having virtually the same problem (without the Qt notification), I would like to take up the answering from here. I installed ROS2 from source and have it in ~/ros2_ws. I have uploaded screenshots of my problem setting. ![RVIZ_problem|690x288](upload://aihdjPHBMJbcfDLTzM5PcaTREt3.png)![Screenshot_rviz2|690x288](upload://9wVKcUtVU7KNG9aJOrBA4BT2mNy.png)There is no ~/ros2_ws/bin/rviz2, only a ~/ros2_ws/build/rviz2 which is a directory. What do you mean by then? Do you have any other ideas why this happens? Thanks a lot! --- [Visit Topic](https://discourse.ros.org/t/rviz2-qt-problem-creating-accessible-interface/3416/8) or reply to this email to respond.
