            Bug ID: 112143
           Summary: Built-in display corrupted after wake-up from S3 on
                    Dell XPS 7390 2-in-1 (Ice Lake)
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: not set
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: inform at tiker.net
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

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.

I've recorded a video to better convey what's happening:

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.
