Re: black screen on opening lid
Well, I had the same Issue with my Samsung 305E5Z and had raised a bug report, when in Beta.
Please read the Comments of the bug report,
my problem was fixed using the then latest main line kernel which I am still using with no problems
I guess it is both graphics and kernel.
~$ uname -r
May the Source be with you !
