I've upgraded to 12.04 and I had to switch from Ironhide to the latest version of Bumblebee.
Now, when I try to run
bumblebeed, I get this error:
FATAL: Module bbswitch not found. [ERROR]Module bbswitch could not be loaded (timeout?) [WARN]No switching method available. The dedicated card will always be on.
I don't really need to use the secondary VGA on Kubuntu, so I would like to find a way to definitely shut the discrete GPU down and avoid wasting battery. I can't disable it from the BIOS because I use it on Windows. My card is an nvidia 540M.
