Hi,
I have the a similarly set up as yourself, and having issue with my two graghic cards, and battery, i used the bumblebee repositories. Which made a big difference for me

....OK I had synaptec open closed it and it ran fine... how do I tell if it is working? setting all seem t pretty much be the same after?
Re: Gforce GT 640M?
from this. To use the discrete graphics card for an application useThe default behavior of bbswitch is to leave the card power state unchanged. bumblebeed does disable the card when started, so the following is only necessary if you use bbswitch without bumblebeed.
Code: Select all
optirun app_name
Re: Gforce GT 640M?
As DS_ED has said in the above reply bumblebee provides power management support graphic card switching.
By default all applications are run through the integrated graphics.
If you need improved graphical performance on the discrete graphic card, you need to invoke it via cli.
Have a read through the wiki as it does explain the usage

Re: Gforce GT 640M?
I saw the usage but seems to still be on by default? just not used? which likks the battery.... How do I test that it is off by default?
and is there no solution to have true auto switching?

Re: Gforce GT 640M?
Try to run the glxspheres program with and without optirun to get an idea which is being used by default.newbi462 wrote:I saw the usage but seems to still be on by default? just not used? which likks the battery.... How do I test that it is off by default?

To check which card is being used by the xServer
Code: Select all
egrep -i " connected|card detect|primary dev" /var/log/Xorg.0.log
