Public bug reported:
Under kernel 6.14 the system's hardware functions as expected. (Aside
from poor performance due to a driver issue.)
Under kernel 6.08 or 6.17, the display shows a very low resolution, a
second monitor is not activated, and networking is unavailable (whether
wired or unwired); indeed, the settings app doesn't even indicate the
possibility of wired networking.
Under kernel 7.0, the display works as expected, including the use of a
secon monitor, and wired networking functions, but WiFi is still non-
functional.
