Cornell's Laboratory for Accelerator-based ScienceS and Education (CLASSE) is pleased to share our Transparent Screen Lock for Enterprise Linux.  Tested on SL6/7 and GPLv2 licensed, this software provides a transparent screen lock over one's desktop.  A configurable list of groups are able to unlock the screen, and logs document who unlocked the screen when.  

This software has been used for over two years and proven useful in kiosk and operational environments where graphical displays need to stay running, updating, and visible, but to comply with various security policies the screen must lock after defined periods of inactivity.  

To download the code or contribute to the project, please visit us on github.  Additional issue reports and any code contributions would be greatly appreciated.
