I have a variant of this problem that I can not find anywhere else: I have the same problem of black screen (white cursor not blinking in the left upper corner) when I do a lock screen!
Suspend problem is also present. Computer goes down correctly after pressing suspend, but when it is supposed to wake up, I get the above described screen (NO splash screen, NO message from grub). I am not sure if I should open a new bug for this....
