I am on Ubuntu 20.04, using a raspberry pi, and following the ros turtlesim tutorial while learning ros.
In the terminal, I used the rosrun command to run a node, which actually opens the node, but then I get the error message "libEGL warning: DRI2: failed to authenticate".
After I get this error, I am unable to type any further command in terminal.
Does anyone have any idea why this is happening?
Reset to default
