Title:
Green pixels on all black screens with Kernel update 5.4.0-64.72
Status in linux package in Ubuntu:
Incomplete
Bug description:
After a kernel update, I noticed that the Linux Mint Ulyssa startup
screen was almost completely green instead of black. Then my desktop
wallpaper looked normal. However, whenever I would open a black page
in a browser or a document on my desktop, it would be filled up with
green pixels and horizontal green lines with large portions of the
black screen colored in green. White pages would have vertical pink
lines.
I thought the screen connector was faulty. However, after checking the
History of Updates, I noticed that a Kernel update (5.4.0-64.72)
happened just when the screen issue started to occur. I therefore
tried and install the previous Kernel (5.4.0-62.70) to see if this
would solve the problem. And it did! No more green pixels on black
screens, nor vertical pink lines on white screens.
