Bug#838211: general: black screen after suspending

[Maicon Rosa da Cunha <maiconrosadacunha@gmail.com>]

Package: general
Severity: important

Dear Maintainer,

Thanks and good work.

I suspend my laptop to not miss work of the college, so, I just call him later
and continue my work, it was expected.
Sometimes, he turns on the screen, but, black screen, doesn't respond, and I
have to restart it by force (which means, removing the battery and put again).
So, most of my work isn't lost due to software that save automatically, but
rather always lose.

I use debian a short time and do not know what it can be.
