I recently bought a Dell inspiron 15 7000 notebook with Nvidia MX150 and a second intel card:
$lspci -nn | egrep -i "3d|display|vga" 00:02.0 VGA compatible controller : Intel Corporation Device [8086:3ea0] 01:00.0 3D controller : NVIDIA Corporation GP108M [GeForce MX150] [10de:1d10] (rev ff)
I’m using debian testing and given the optimus technology I installed Bumblebee and mesa-utils (I followed the official debian doc here):
sudo apt-get install bumblebee-nvidia primus
Running the glxgears -info command everything is ok, the window appears with the gears turning. But if instead I launch glxgears with optirun, nothing happens, no errors, and the window with gears does not open:
optirun --debug -vv glxgears -info [ 860.333401] [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf [ 860.334195] [DEBUG]optirun version 3.2.1 starting...

I do not think there are errors …
This is the optirun and bbswitch state:
$optirun --status Bumblebee status: Ready (3.2.1). X inactive. Discrete video card is off. $cat /proc/acpi/bbswitch 0000:01:00.0 OFF
If I run something randomly with optirun, like Firefox and re run the above commands:
$optirun --status Bumblebee status: Ready (3.2.1). X is PID 2908, 1 applications using bumblebeed. $cat /proc/acpi/bbswitch 0000:01:00.0 ON
it seems that with Firefox (a random thing) launched with optirun Bumblebee is active …
Can I therefore deduce that it is a glxgears problem that does not appear, but is everything well configured? Or something is wrong?
Can you advise me some tests to do?
