Same with me but on samsung netbook. After wake up from sleep, just black screen. I can't go to tty shell, magic sysrq also not working. Nothing, but just black screen, I have to force poweroff, i'm afraid to "sleep" again

Updated bug report.

After the latest updates I no longer need to plug an external monitor to wake up normal like I did in Precise. The details are in bug report.
