A nasty shock lay in store for me this morning, when i attempted to Resume my Tower from its night's sleep [Suspend]. This routine process previously has not let me down since i adopted Maui, & i do it daily, so i don't understand what went wrong last night when i Suspended [it all seemed normal], or this morning during my attempt to wake it up [Resume]. My attached pic shows the unpleasant error msg that appeared on the monitor, instead of the expected usual Unlock screen.
I have two sets of questions wrt this shock:
1. Why would this have occurred? Is a root cause known? Can i do anything to avoid it repeating?
2. Contrary to the screen msg instructions, i could NOT salvage this, & had to REISUB. I could not get to a tty; Ctrl+Alt+F2 [or +F1, +F3, +F4, +F5, +F6] simply produced a black screen. Whilst this screenlocker failure event was a first for me, failure to get to a tty has happened a few times before in Maui --> WHY? What is wrong with my installation that the commonplace method to migrate from graphical session to tty does not work?
