LMDE & Bumblebee

[kristof]

I'm running LMDE on a Dell Vostro 3750 with Bumblebee installed to support the Nvidia Optimus stuff. The only time I really want to use the Nvidia card is when dual booting into Windows. I'm a little confused though, as I thought Bumblebee's power management allowed you to do just that, i.e. use only the Intel card unless a program was specifically launched using optirun. However I find when randomly checking the status of the card here and there that often it's been turned on for reasons unclear to me:

Code: Select all

kristof@kristof ~ $ more /proc/acpi/bbswitch 
0000:01:00.0 ON

I've been turning it off using

Code: Select all

kristof@kristof ~ $ sudo rmmod nvidia
[sudo] password for kristof: 
kristof@kristof ~ $ sudo tee /proc/acpi/bbswitch <<<OFF
OFF

which appears to work fine. Does anyone know of a better 'permanent' solution to instruct Bumblebee never to turn on the card unless I explicitly ask for it?

Hola Kristof,

I experienced something similar, here are 2 things you should check:

1. make sure the bumblebeed daemon is running - if not, the card will be on. the bumblebee install gives you an init startup script
2. see the module options on bbswitch page and set both states to 0

Hope this helps

Turn it off for good.
Disable NVIDIA in Optimus and run Integrated Intel graphics only:

the links to install Bumblebee on Squeeze and Wheezy (in SolusOS 1 & 2) have a better fix if this problem persists:

The following is a fix (avoids libvdpau probe activating Nvidia GPU) that ensures the NVIDIA card stays OFF when not in use by optirun.
