Re: Nvidia/Intel switching nightmare.

  Thread Previous • Date Previous • • Thread Next 
Hi,
Excellent tutorial, this is just what was needed to pull together all of the information this group has provided so far. Good work. 

There is a typo (/etc) on the line
	> sudo chmod +x /ect/init.d/switch-graphics

Also on my system (Z11WN) I did
	> sudo gedit /etc/modprobe.d/sony-laptop.conf
and created a file containing the following:
	options sony-laptop speed_stamina=3

Simply running
	> echo speed > /sys/devices/platform/sony-laptop/speed_stamina
switched the light on, but does not affect lspci output.
I was going to mention the kernel parameter too! Also I think 2 reboots are necessary.
Also on my system, the included xorg.conf failed to start. However running nvidia-xconfig after rebooting with the kernel parameter (i.e. once the lspci output only shows the nvidia card) worked. 

Thanks,
Anthony.

Hello Didine,
I just realized that I forgot the change to the kernel parameter at startup. In the attached PDF you will find this near the end. 

Cheers,

        Hi all.

        I just compiled a tutorial for the configuration of the graphic
        cards. See the attached ODT or PDF.

        Feedback welcome. Please point out errors.
