Screen Messed Up After Wake Up from Sleep

[cg2916]

When I open the lid of my laptop, the screen is messed up. It seems to be that this one small square repeats itself throughout the entire screen (will take picture if needed).

Any idea why this happens?

Some hardware simply isn't compatible with sleeping/hibernation in ubuntu. What pc is it? If you post the output of
lspci perhaps will give a clue.
