Troubleshooting: Some Student Screens Are Not Showing | Last update: September 14, 2016 Your student screens may not show for a variety of reasons. The following troubleshooting tips offer possible solutions: Make sure that the email address for the user listed in Launch is a 100% match to the email address used to sign into the Chromebook. Make sure that the username for the Windows user is a 100% match to the username used to sign into the Windows device. For Chromebooks try signing out and then signing back in. For Chromebooks make sure the Lightspeed Management for Chrome agent is installed and is enabled. It’s possible that the student is “active” in another group. Students can only have screens viewed in one group at a time. Make sure that your teachers end the orchestration after the end of the class period. Please note that iPad screens cannot be seen.
