DRM IOCTLS come regularly(every minute) still even after screen off

Thu Sep 16 06:27:12 UTC 2021

Good morning,

for the background I advised to contact you Michel since we couldn't 
find an explanation.

Alex explanation might be correct, but the CS seems to come from the X 
server and is always roughly 60 seconds after going into power save.

Any idea what that could be?

Thanks,
Christian.
