Public bug reported:
I have a fresh install of Kubuntu Wily Beta 1. My laptop is a Dell XPS
15 with a Nvidia video. I tried both drivers nouveau and nvidia with the
same result.
I can reproduce the error ALWAYS, when I put the laptop to sleep it wont
resume, I can see the power light and the keyboard backlight turning on
as if it will wake up, but then just a black screen. I cannot even
switch to a terminal (Ctr+Alt+F1), the only solution it to restart.
The problem is not only when sleeping, it also happens when the screen
is turned off by Power Management.
