Bob,

Thanks for the confirmation that you have i915 graphics. I am pretty sure we
have identified the issue.

For you, the immediate workaround should be to disable dpms.

If you require functioning dpms and want to add your voice to either of the
substantive Debian bugs requesting the suggested fixes are implemented, please do.

Best wishes

Mark
