<span class="quote">> I have a Dell XPS 7390 2-in-1, which use a "Intel(R) Core(TM) i7-1065G7 CPU
> @ 1.30GHz". While the machine defaults to s2idle, energy consumption in that
> state is high, which led me to investigate S3 sleep, enabled by

> echo deep|sudo tee /sys/power/mem_sleep

> This works well, except for one annoying showstopper wrinkle: The machine's
> built-in display remains on a corrupted version of the Dell logo after
> wake-up. All other aspects of the machine (including externally attached
> displays) resume entirely fine, but the internal display remains garbled
> until a reset or power cycle.

> Notably, the pixel pattern in the corrupted logo *does* change in response
> to interactions with the system, meaning that likely *some* part of the
> framebuffer is being shown, but display state is not sufficiently reset to
> enable proper display function.
