A picture is worth a thousand words:


One moment, I was using my Fedora installation, and went to the bathroom to come back to this. Initially, I thought maybe the display driver crashed or something so I restarted the entire machine to find the same result. Interestingly enough, you can see the boot lenovo logo retained even after it went to the login screen. That's sort of an effect I've seen with bad screens, but this panel is actually new that I got and replaced a year ago.

I thought maybe it's my processor's integrated graphics, but uh, upon swapping the CPU for another one I had, this problem didn't change. External video is fine, so I see two possibilities here:
  • Somewhere along the circuitry, output from the Integrated Graphics gets messed up and this is the result, and that is based on how external video is fine, which I assume gets handled by the dedicated GPU as opposed to integrated graphics.
  • The screen itself went bad because it's an aftermarket product (From Chi-Mei INNOLUX, though, which is the same manufacturer that made the original panel).
Or so it was at first. When I tried it again this morning with the older Pentium CPU hooked onto an external display, fedora booted onto emergency mode after initramfs failed, which is really bizarre. It made me think that maybe memory is bad, because journalctl gave me such problems, and it would explain the corrupted video since integrated graphics use RAM, so I swapped memory with several modules for the same result with no change whatsoever.

So, I don't know. Is it the screen? Why did fedora fail all of a sudden and a day after the screen issue? I would guess that maybe that something in the laptop (like a chipset, or individual component) is failing, but I've never seen anything fail this so way before, so I'm a bit ( a lot) lost.

Can anyone point me towards suggestions?
