Description:
I followed the wiki to enable power management of my NVIDIA QUADRO K2000M and the Ivy Bridge i7 3610QM IGP, but bbswitch still doesn’t switch between the Intel and the NVIDIA graphic card.

Here’s the output I’m based on to support what I say:

skp@iris ~ % lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GK107 [Quadro K2000M] (rev ff)

skp@iris ~ % ps aux | grep bumblebee
root 637 0.0 0.0 29792 1308 ? Ss 20:01 0:01 /usr/sbin/bumblebeed --daemon
skp 2551 0.0 0.0 8456 1052 pts/3 S+ 20:44 0:00 grep bumblebee

skp@iris ~ % lsmod | grep bbswitch
bbswitch 5042 0

skp@iris ~ % cat /proc/acpi/bbswitch
0000:01:00.0 OFF
skp@iris ~ % optirun glxgears > /dev/null &

skp@iris ~ % cat /proc/acpi/bbswitch
0000:01:00.0 ON
skp@iris ~ %
[1] + done glxgears > /dev/null
skp@iris ~ % cat /proc/acpi/bbswitch
0000:01:00.0 OFF

skp@iris ~ % glxgears > /dev/null &
[1] 2665
skp@iris ~ % cat /proc/acpi/bbswitch
0000:01:00.0 OFF
skp@iris ~ %
[1] + done glxgears > /dev/null

So, let’s sum up. I have X launched with bumblebeed. So bbswitch is also loaded, so I wouldn’t have to explicitely ask for a switch. I posted the optirun sequences to show up that it works if I explicitely tell the cards to swap.
