Yellow and blue bars after wake

After waking from sleep, these yellow and blue bars appear. I can move my mouse. After 5-10seconds, the bars dissapear but the screen is completely frozen and I cannot move my mouse.

Is the windows stuff necessary? Whats actually the useful part?

it fools the BIOS into offering up the acpi features to linux… it worked on my older machine.

Whats the point of that and how does it relate to the graphical glitch?

it looks like you are not writing vram to disk at suspend, so when you resume it pulls in random 1’s and 0’s until it refreshes.

the first step toward getting a nvidia driver to write vram to disk is to get suspend/resume working properly

here is the wiki article.
