Bug#761583: mate-desktop-environment: One screen goes black after resume from screensaver

[Kasper Loopstra]

Hi Mike,

Actually, after investing in a new screen this stopped happening. It
really looks like the backlight in my old TFT display was to blame, and
not the desktop environment. Sorry for the noise.

Thanks,

Kasper.
