Bug#703948: regression: suspend to ram leaves laptop screen black after restart (additional information)
to add some more information to my previous bug report: I disabled suspend
on laptop lid close, now I can explicitely suspend to ram and, upon resume,
I can close and reopen the lid and the screen is turned back on (the second
time).
One more important piece of information I had forgotten: I attach my
hardware configuration, which is relevant for debugging suspend/resume.
Bye
Giacomo
