Problem running line follower script on ROS
Hello,
I am trying to run a line follower python script (with opencv) on a Kobuki robot with a Rasperry Pi and Ubuntu 16.04.
When I try to run the code, following errors occur:
QXcbConnection: Failed to initialize XRandr
Qt: XKEYBOARD extension not present on the X server
libEGL warning: DRI2: failed to create any config
I already tried to install OpenGL, but it was not successful.
Do you have a suggestion?
Thanks in advance
Regards, Chima
