I bought a Lenovo thinkpad edge e330 laptop, I5, intel HD 4000, I have a problem with screen being too bright and desaturated. Brightness can be changed but that is not the issue.
The laptop had Win7 installed and had options for gamma and contrast but nothing worked.
Is there an way to manipulate the gamma & contrast on Linux?
When idle and screensaver sets of, black color, it stays as it is on the picture, like a flash light.
Is this a faulty screen?
check out the difference, in the back is my desktop with black bg, in front is the laptop...black bg.
