I've been experiencing the same problem after doing a full update on my Dell Vostro. I did not update for several months and after the update few weeks ago, the screen and keyboard were frozen after resuming. I found that the network (ssh) was still alive, and by doing some activity by network I could "defreeze" my system. But it remained very slow.
Yesterday I removed 'systemd' package and updated others lib systemd packages and problem has gone ! If you haven't too much packages depending on systemd you may try if it works for you (i had to remove MATE (not used, i use Xfce), Network-Manager (replaced by Wicd)).
