Comment 2 for bug 1382673

This happens on my Dell Latitude D630 very frequently after my Mint 17 upgrade. Sometimes, right when the screen goes black, I can close the lid and it will go to sleep, when I open the lid again, it wakes up and the display works again; otherwise, recovery isn't possible. (I haven't tried any clever recovery steps via SSH, because I don't know what those might be.)

I managed to catch the problem in logs, as well through the successful sleep/wakeup workaround.

Hopefully, these logs can shed some light for someone who knows how to interpret them.
