I normally work connected to my big screen with external keyboard and trackball. I have no issues with either the screen or the keyboard doing a normal reboot. However, when rebooting after a system update, the one with the options to select normal start up or memory test, I get the display on my big screen, but it doesn’t recognize my keyboard! I have to hit enter to select start up on the laptop. Then the login prompt shows up - but only on the laptop, not on my big screen, and now it recognizes the external keyboard to type in my password! Once I am logged in, both big screen and keyboard start working again.
I am still experiencing my monitor/keyboard not being recognized but only after a system update reboot. Is anyone else seeing this? Is there anything I can do to make it work properly?
