So it appears you lost rw permissions on /dev/dri/card0. That is primarily an issue with the login/session manager (as it should be setting up the permissions when you login). If you are a member of the video group, you can fixup the issue with 'sudo chgrp video /dev/dri/card0 ; sudo chmod g+rw /dev/dri/card0'
