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.
