Hi, hope this is in the right place. Fired up PC and saw “No EDID read” error. I’ve barely an idea what that even is. Browser returned “How to fix "no EDID read" on Linux 5.6.0” as the top answer; I barely understood a word of what you are supposed to do in this event; even whether it was critical or otherwise.
“xrandr --verbose” (below) seems to return the necessary information; but what do I know? My ignorant flaying around lately has left me not wanting to touch anything that might crash things that’ll take another week of ignorant flaying around to fix; so here I am. Does “xrandr --verbose” look right or do I need to take action? The linked topic’s answer is a little beyond me and any help would be appreciated. Thanks
Sorry, I’d attach “xandra --verbose”, but don’t know how. Output printed below:
