io vorrei sapere i passi per abilitare la scheda chipset
nel frattempo ti riporto quanto ho scritto in un altro thread:
I finally managed to unlock some BIOS options. http://i.imgur.com/3TBTgyc.jpg
BUT using "Others" option is just disabling HD4000 and enabling 650M only working with hdmi port video out, no lcd output.
Another kind user of this forum was telling me that there's no physical connection from 650m to lcd but just through hd4000.
So if anyone can explain how to unhide the "Chipset/Graphic" section I will try if just a bios edit will drive me to another step.
Meanwhile, digging in early linux efforts to use Optimus on linux I found this page:
It's about 100 lines of code.
Maybe someone could create a module for Chameleon or Clover?
One last thing from Wikipedia:
Operation without a device driver
When no software mechanism exists for switching between graphics adapters, the system cannot use the NVIDIA GPU at all, even if an installed graphics driver would support it. Some older computers contain a BIOS setting to manually select the state of the hardware multiplexer to switch output between the two video devices.
***However, this setting is no longer part of the Optimus platform.***
So the famous "mux" chip is no longer present or supported?
Source code for Linux Noveau is here. Applies to the cards also listed here. Maybe the solution lies around here.http://nouveau.freed...nvc0familyfermi
