Artifacts on screen, not sure if LVDS cable loose or GPU issue
(see the video) I am getting screen artifacts after boot chime, not sure if the LVDS cable is loose from behind the display (on board is fine) OR GPU issue (Redeongate).
Update (08/29/2020)
I see similar artifacts on an external monitor, I immediately closed lid after pressing power button (see image below).
Can this be a RAM issue ? as I had to reseat RAM couple of times, as I was getting continuous chimes on boot.
Update (09/02/2020)
I finally resolved it. I booted into system rescue CD and then SSH’ed into the MacBook. Then I followed the guide here
I followed the last steps (for archlinux (system rescue CD ver 6 & greater is based on archlinux)
Then followed the steps to disable csrutil > Nvram change > remove kext. well instructed in this post
I noticed that the left Shift key, 7, 8 & 9 keys aren't working, Any ideas why that would be ?
Is dit een goede vraag?
