Problem running line follower script on ROS

asked 2019-11-13 14:49:31 -0600

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
