[Solved] - Tower's 1st [no, 3rd] Hard-Reset since clean-reinstall.

It is really a strange thing that the mouse and keyboard input fails but you are able to switch to tty and relogin which tells us that the kernel is not frozen or crashed.

Agreed, & remember that my REinstallation of Maui was 31/12/16; since then there has been more than only two kernel updates come through, meaning that these problems have occurred across multiple kernels, ie, it logically cannot be a single defective / incompatible kernel.

So that means the issue either is in the graphics driver or the mouse and keyboard driver.

Well, re "graphics driver", if you've followed this thread you'll know that i stayed stubbornly with the NVidia driver for a long time [with a couple of different updates of it], but now i use Nouveau. The freezes have occurred both ways. What else could i do?

Re "mouse and keyboard driver", again, what can i do here? I simply use whatever is provided in the OS. 

Is the graphics frozen in any case? Or do you get new notifications and such and only mouse and keyboard is frozen/not working?

That's a very good question, & i regret that for this morning's incident i cannot answer... unfortunately i tried those above-documented steps, ending in the Hard Reset, before Thunderbird [one of the programs still open at time of last night's Suspend] had time to synch & download new emails. Remember in my older post, Thunderbird & Network Manager etc were still clearly running behind the frozen plasmashell, coz i had heard the new message alert sound. If/ when there is another freeze, i will wait a little while before resetting, listening for TB.
