I'm running ROS 1 Noetic on Ubuntu 20, using PuTTY to forward X11 to Xming on Windows 10. RViz and Gazebo work fine, but when I run rqt, I get an error:
X server does not support XInput 2
failed to get the current screen resources
The X11 connection broke: I/O error (code 1)
Any explanation or solution is appreciated.
