bbswitch does not work on Nvidia GT750M

[goldhoorn]

I'm Running a Ubuntu 12.04 On a Dell Inspirion 15 7537

The result from modprobe/dmesg:

I'm a Computer scientist, so ping me if you need additional help...

It usually indicates that the kernel did not match ACPI device handle correctly. Try a newer kernel (3.12+ preferably).

This was a fast reply. I updated to 3.13.5-031305-generic and this solved the first issue

Unforunatly i had do install the nvidia driver manually by downloading from nvidia.com. I successfully loaded the kernel module and adapted /etc/bumblebee/bumblebee.conf by inserting driver=nvidia and kerneldriver=nvidia. After a reboot i now get:

$ optirun --debug --verbose glxinfo [ 528.944408] [INFO]Configured driver: nvidia [ 528.944525] [DEBUG]optirun version 3.2.1 starting...

Am i right if i assume that my card is not corretly recognized from the nvidia driver itself?. How can i debug this more in detail?

(again thanks for your fast reply)

Are you aware of the patches needed to run nvidia on 3.12+, 3.13+?
