I have an LG monitor connected through HDMI to my FW Desktop 128 GB. Worked flawlessly before the update. Now after update, the screen does not wake up after the system has been idle. I have to restart the system and wait for it to reboot to get access to my machine.

Update: It seems that the system does not sleep as it used to (no flashing power button) ; it just turns off the monitor, and does not turn it back on when a key is pressed. In the past, the system always went to sleep.
