I have just run
yaourt -S dkms-bbswitch-git
The command uninstalled bbswitch that was installed for kernel 3.5.3-1 (x86_64) and installed a new wersion for 3.5.4-1.
I haven't run any optirun <something> yet, but
sudo modprobe bbswitch
worked as well as
cat /proc/acpi/bbswitch
So hope this will help you.
]]>cat /proc/acpi/bbswitch
I get the following error:
cat: /proc/acpi/bbswitch: No such file or directory
If I try to run
sudo modprobe bbswitch
I get:
ERROR: could not insert 'bbswitch': No such device
I have already installed bbswitch.
Finally If I run:
optirun glxgears
I get
[ 2585.015815] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please
[ 2585.015922] [ERROR]Aborting because fallback start is disabled.
I boot my system with parameter
pci=noacpi
and I suspect that parameter prevents to load nvidia drivers and bbswitch. Is that true?
I have Dell Inspiron N7110 laptop.
