Hi everybody!

Distro: Ubuntu 12.04.1 LTS

Kernel:
3.2.0-33-generic-pae #52-Ubuntu SMP Thu Oct 18 16:39:21 UTC 2012 i686
i686 i386 GNU/Linux

Manufacturer and Model:
baseboard-manufacturer: Acer
baseboard-product-name: JE50_HR
baseboard-version     : Base Board Version
system-manufacturer   : Acer
system-product-name   : Aspire 5750G
system-version        : V1.20
bios-vendor           : Acer
bios-version          : V1.20
bios-release-date     : 03/16/2012

Bumblebee version: 3.0.1

Issue:
When putting the laptop to sleep (suspend), waking it up immediatly or
some time later sometimes fails. The result basically is a black screen
with the mouse cursor on it. I can still move the cursor and it also
changes to a text cursor somewhere in the middle of the screen where
you usually unlock the screen. I can even unlock the screen by
clicking there, typing my password and hitting return. When moving the
cursor around the screen it again changes according to the positions
of windows I had open before suspending. I can also switch to a console.

Also tried the latest upstream kernel for Ubuntu with same results.

I'm not exactly sure if this is a Bumblebee bug, a kernel bug or a bug
in some other package and it's
a bug, that is really difficult to reproduce, but I thought, maybe you
are able to help me with this by looking at my system's configuration
and logs because this bug is really annoying when it comes up.

It seems to be some kind of graphics issue though, since windows and
everything is still there. There just kind of not shown.

I tried "unity --replace" after switching to command line which
brought back the background image instead of the black screen. Windows
also appeared for a second or so but disappeared immidiately.

Please let me know, if you need any additional logs.

Thanks in advance,
Hendrik
