Bug#870641: Solved?

[Guus Ellenkamp]

I have been struggling for a long time with a laptop sometimes not 
waking up after sleep. I read some stuff here and indeed strange this 
bug is still there. I just installed LightDM 1.30, but as I don't fully 
understand the problem I am not sure if that would solve the problem. 
Pressing keys (CTRL-FX) and such doesn't seem to help, as some people 
sugget.

I am happy to help, but as said, I don't fully understand the problem 
where I saw some people do.
