xps 13 plus screen blanking issue

[cbeley]

Frequently, screen blanking does not work for me (screen turns off, then turns back on with a cursor on a black screen).

Could be related to https://gitlab.freedesktop.org/drm/amd/-/issues/662 I'm not on an amd GPU.

Issues mentions https://github.com/dwagelaar/enforce-dpms, which seems like it could fix my problem, but it is not ideal.

https://gitlab.freedesktop.org/drm/intel/-/issues/7581 suggests Kernel 6.1.0 may fix this issue. Ubuntu 23.04 ships with Kernel 6.2, so that may fix my issue. I'm delaying upgrading though right now since I can't risk disruption with my laptop.
