Bumblebe and 840M

[simara]

Hi everybody,
I post this message because my Bumblebbe doesn't seems to work...
My hardware
HP envy 17' touchsmart
geforce 840M
16 GO of Ram.

I've installed Bumblebe with the porprietary drivers (urpmi bumblebee-nvidia). I've also add the backport 32 bits. (urpmi libvirtualgl libturbojpeg0 libprimus)

I launch my steam without problem whit the comand primusrun %command%in the launching games option . The glxspheres64 test is also good

With or whithout bumblebee, in normal use, i have 3 hours of battery instead of 6 or 7 in windows...My graphic card is always running, even with bbswitch...(powertop gave me the info). So My request is help for turning off my discrete card...
Thanks for your help

Thank you but, my problem is that the discrete card is already running when i launch a session,even if an optirun --status say that its is OFF...
( I see i quote of St Exupery, you're french?)

FWIW, you did check this section:

Known bug: Since kernel 3.19, the nvidia driver, once loaded, is not unloaded anymore when the applications using it stop (mga#16094). Which means that the discrete card stays powered. There is a way to turn it off manually, thankfully. As root:

Code: Select all

rmmod nvidia && tee <<<OFF /proc/acpi/bbswitch

And where exactly do you check in powertop that the device is still enabled? Under device statistics tab?

Please also go through https://github.com/Bumblebee-Project/Bu ... leshooting
Also the very last section in http://nouveau.freedesktop.org/wiki/Optimus/ might also be relevant, even if that's for optimus (it does apply to nvidia cards, after all).

If that does not help, then this seems to be a bug, you should report that, after searching if it hasn't been reported yet already: https://wiki.mageia.org/en/How_to_report_a_bug_properly
For completeness's sake and also to allow others to follow up on that bug report, please also post the link to it here in the thread, thanks.
