Left monitor display becomes garbled

[Jay Ridgley]

Good afternoon,

Thanks ALL, here is an update..

In addition, and as requested a bit more information (OK, more than a 
little).

I have not tried re-seating the Graphics card, yet. I am not a hardware 
type guy and it is not easy for me to get to the box to disconnect it.

Have not swapped the monitors, yet. The cables are wrapped and I do not 
have a set of spares handy.

The problem has not manifested itself since my first report. So I have 
not tried the ctl-alt-fn.


Liam, I will eventually get it through my thick skull that I need to 
supply as much info about my s/w and h/w as I can when asking for help.
Yes, I am running Gnome 3 and also X11.

I know nothing about Wayland and really do not want to learn it, sorry.

Below is the hardware info, I have found so far...

The next time it fails I will do what I can to isolate the problem.

Thanks,
