After allowing the new kernel update (5.15.0-82-generic)
and rebooting the display on the screen appeared and reappeared, flickering
repeatedly.
This performance appeared after a reboot of the new kernel and after I walked away and Mint generated the black screen after no use that I had it set to. Upon moving the mouse to wake the system up that's when the flickering began and the system was unstable/unresponsive.
Dropping to a shell and running sudo shutdown -h now didn't work. The command failed and bash produced "Expanded Security Maintenance wasn't enabled".
Curious I ran: 'apt list --upgradable' to see what was available.
This entailed and pointed to Intel Microcode. I don't have and Intel tech on this rig:-
The dmesg log shows apparmor as being denied:-
I'm not an expert with the dmesg log. There's a lot of output in that log so it could be something else. IDK.
There are a handful of entries for patches to the microcode and one update for the microcode driver.
See the file attached:-
Hopefully it's not a kernel bug or a Wayland or X11 driver issue. I'll be back to see what you guys think of this.
I hope I can walk away, fire up the grill and when I come back to move the mouse this doesn't become a repeat.
