Hi Dirk,
Sorry for the late reply! Please do take care to cc the actual bug
report as well instead of directly replying only to me (there's a good
chance for stuff to just get lost in my inbox, unfortunately).

Dear Maintainer,
since I've the same issue with the same Debian-Jessie System and bumblebee I
feel free to answer your message and provide the additional Information you
asked for.
My "bumblebee", "xserver-xorg" and "xserver-common" versions are the same as
in Mareks post which I answer.
I've attached a file with all information you requested.
Next time please either reply inline or put everything into a text
file, not an OpenOffice/LibreOffice Writer document.
..yes, sorry I'll do so..
According to your /var/log/Xorg.8.log logfile, it looks like the
problem is that for some reason the nvidia driver is unable to detect
your nvidia GPU, i.e.
[ 9176.525] (II) NVIDIA dlloader X Driver 340.46 Wed Sep 24 13:34:03 PDT 2014
[ 9176.525] (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs
[ 9176.525] () using VT number 7
[ 9176.525] (EE) No devices detected.
[ 9176.525] (EE)
Fatal server error:
[ 9176.525] (EE) no screens found(EE)
[ 9176.525] (EE)
Please consult the The X.Org Foundation support
for help.
at http://wiki.x.org
Is your nvidia GPU supported by nvidia-driver 340.46? See supported
products section at [1]. Otherwise, you may have to set the BusID
manually in /etc/bumblebee/xorg.conf.nvidia. Refer to the comments in
that file for a brief howto.
Regards,
Vincent

Meanwhile I found the solution which I posted on GitHub where I looked
also for a solution. See the conversation here:
https://github.com/Bumblebee-Project/Bumblebee/issues/580
The solution (for me) was, that I had to DELETE the BusID parameter in
my "/etc/bumblebee/xorg.conf.nvidia". I set this parameter at first
manually, as you suggested. I checked twice if it was the correct
number, but the error message remained.
After deleting it, bumblebee worked! A "vblank_mode=0 optirun -b primus
glxgears -info" now gave me 945 fps instead of the 60 and a "cat
/proc/acpi/bbswitch" showed me the card was ON.
But whenever I UNCOMMENT the "BusID:xxx" line in the xorg.conf.nvidia,
the error message returned again.
I can't say for sure, if the latest nvidia driver update to version
340.65-2 has something to do with it too, as was mentioned on GitHub,
because I'm not sure any longer, if I tried bumblebee the first time
without this parameter also or not. I only know that I set and uncomment
it then.
Thanks for answering and
Kind Regards
Dirk Linnerkamp
