My display is showing display issues similar to the ones showing in another thread. The visual issue happens when my SAMSUNG 970 EVO SSD is mounted/selected in Linux. I have tried multiple different power plugs and outlets to try my best to eliminate power issues that I saw referenced in other posts.
This is my first Khadas device so I am sorry if I have missed something simple.
I have used 4 different USB C cables of different make with 3 different adapters (15W, 18W).
I reseated the heatsink and M2 Expansion adapter and made sure separation was kept (using thermal pads) to try and keep possible shorting points to a minimum.
I have also used 3 different monitor (4k, 1920x1080, and another basic 1080p) and tried 3 different HDMIs with each.
The visual issue is present on all combinations that I have tried. The issue will stop immediately if I select to unmount the drive through the GUI or cmdline, and starts again if remounted.
I think I actually figured it out. Feel kinda dumb .
I believe the issue was that I was still using the USB port that is shared with the PCIE. The visual impairment happened for a few seconds after unplugging the peripheral from that port, but it now seems to be working ok.
I will update if the visual starts to mess up again in the same way now that I am no longer using that port.
