Re: Problems with hibernation - randomly cannot resume.
One data point: on my system running Testing (kernel 4.08) I can
hibernate using hibernate-disk and wake up with no problem. Any suspend,
or hibernating from the Xfce menu, and on return there's what I believe
is an nVidia graphics problem that is not recoverable. I believe that
because if I press Ctrl-Alt-F1, I get a sub-second flicker of the
terminal login prompt, then the black screen with flashing hardware
cursor at the top (0,0) position (and no visible response to any
keyboard/mouse commands). That black screen is what I see whenever
returning from suspend.
I haven't tried any other debugging stuff (e. g. switching Xorg to the
VESA driver, or using ssh to see if the system is still active even when
I can't get a reaction from the screen)) yet.
I'm going to be traveling and won't have access to this box for a few
days, so I won't be able to do anything about this for a while.
Suspend/hibernate worked correctly on this same system with Jessie.
