Reloading window manager restarts X with: (EE) AMDGPU(0): failed to set mode: Permission denied

I am using debian unstable with enlightenment as window manager. If I run kill -HUP <enlightenment pid> from a xterm running in enlightenment then I can reload enlightenment without issues, but if I do the same from a console or logged in via ssh then X restarts with the error message (EE) AMDGPU(0): failed to set mode: Permission denied (complete Xorg.0.log.old 

Is this "Permission denied" error something that can be fixed by granting the necessary permissions? Or is this a bug and should be reported?

Thanks for your help
