Hi,

Been trying to see where to log a bug (Launchpad, gihub...) but couldn't
see anywhere. Please excuse me if this is the wrong place.

Hardware: Lenovo T430 wth nvidia nv5400m discrete
OS: Kubuntu 15.10, kernel 4.2

I've tried nvidia-352 and nvidia-355 with Bumblebee; both seemed to work
fine. I then decided to try nvidia-361 and encountered problems with
getting bumblebeed: sudo service bumblebeed restart
tail /var/log/syslog
Feb 15 23:57:42 lappy systemd[1]: Started Bumblebee C Daemon.
Feb 15 23:57:42 lappy bumblebeed[3446]: [ 1312.560561] [ERROR]No discrete
video card found, quitting
Feb 15 23:57:42 lappy systemd[1]: bumblebeed.service: Main process exited,
code=exited, status=1/FAILURE
Feb 15 23:57:42 lappy systemd[1]: bumblebeed.service: Unit entered failed
state.
Feb 15 23:57:42 lappy systemd[1]: bumblebeed.service: Failed with result
'exit-code'.

I did some other basic checks.
1) The nvidia card is not reported when it should be: lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09)

2) I can't: cat /proc/acpi/bbswitch
cat: /proc/acpi/bbswitch: No such file or directory

My uneducated guess is that something in nvidia-361 is messing with
bbswitch. Are there any other checks or data I should collect before revert
to nvidia-355?
